c# 网页打印全流程
说明：我要实现的就是将数据库中Group表的数据查找出来，替换打印模版中的内容，再将模版文件打印出来
1、准备好要打印的模版group_O_train.html
1 <div class="pagetitle title">出国(境)培训人员汇总表</div> 2 <div>项目编号:{项目编号}</div> 3 <table class="pagedtable" style="width:25cm;font-size:9pt;border-collapse:collapse;" cellspacing=0 cellpadding=3px border=1 bordercolor=black> 4 <thead style="text-align:center"> 5 <tr> 6 <td style="width:0.6cm">序号</td> 7 <td style="width:1.5cm">姓 名</td> 8 <td style="width:0.8cm">性别</td> 9 <td style="width:2.0cm">出 生<br />年月日</td> 10 <td style="width:1.5cm">出生地</td> 11 <td style="width:1.0cm">政治面貌</td> 12 <td style="width:4.5cm">工作单位</td> 13 <td style="width:2.7cm">职务或<br />职 称</td> 14 <td style="width:4cm">何年毕业于<br />何校、何专业</td> 15 <td style="width:2cm">目前从事的<br />实际工作</td> 16 <td style="width:1.0cm">备注</td> 17 </tr> 18 </thead> 19 <tbody> 20 {人员名单} 21 </tbody> 22 </table> 23 <p class="alignright" style="width:25cm">出国(境)归口管理部门公章</p>
2、打印通用页面，其中<div id="pPrintContent" runat="server">是模版要替换的内容
1 <%@ Page Language="C#" AutoEventWireup="true" CodeFile="DocumentPrint.aspx.cs" Inherits="Abroad_DocumentPrint" EnableViewState="false" %> 2 3 <html xmlns="http://www.w3.org/1999/xhtml" > 4 <head runat="server"> 5 <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1" /> 6 7 <title>打印</title> 8 <link href="../css/print.css" rel="stylesheet" type="text/css" /> 9 </head> 10 <body onload="PageSetup_Null()"> 11 <form id="form1" runat="server"> 12 <object id="WebBrowser" width=0 height=0 classid="CLSID:8856F961-340A-11D0-A96B-00C04FD705A2"> 13 </object> 14 <div class="printbar"> 15 <div style="float:right"> 16 <a href="javascript:void(0)" onclick="print()"><img src="../images/printbutton.gif" border=0 / alt="打印"></a> 17 <a href="javascript:void(0)" onclick="printtrainmember()" runat="server" id="btprinttmember"><img src="../images/printbutton.gif" border=0 / alt="打印培训人员" ></a> 18 <a href="javascript:void(0)" onclick="printPreview()" ><img src="../images/printpreviewbutton.gif" border=0 / alt="打印预览"></a> 19 <a href="javascript:void(0)" onclick="window.close()"><img src="../images/closebutton.gif" border=0 / alt="打印"></a> 20 </div> 21 </div> 22 <div id="pPrintContent" runat="server"> 23 错误,没有内容!请检查调用参数是否正确. 24 </div> 25 </form> 26 </body> 27 <script src="../js/print.js" type="text/javascript"></script> 28 <script type="text/javascript"> 29 var HKEY_Root,HKEY_Path,HKEY_Key; 30 HKEY_Root="HKEY_CURRENT_USER"; 31 HKEY_Path="\\Software\\Microsoft\\Internet Explorer\\PageSetup\\"; 32 //设置网页打印的页眉页脚为空 33 function PageSetup_Null() 34 { 35 try 36 { 37 var Wsh=new ActiveXObject("WScript.Shell"); 38 39 HKEY_Key="header"; 40 Wsh.RegWrite(HKEY_Root+HKEY_Path+HKEY_Key,""); 41 HKEY_Key="footer"; 42 Wsh.RegWrite(HKEY_Root+HKEY_Path+HKEY_Key,""); 43 44 HKEY_Key="margin_left" 45 Wsh.RegWrite(HKEY_Root+HKEY_Path+HKEY_Key,0); 46 47 HKEY_Key="margin_top" 48 Wsh.RegWrite(HKEY_Root+HKEY_Path+HKEY_Key,0); 49 50 HKEY_Key="margin_right" 51 Wsh.RegWrite(HKEY_Root+HKEY_Path+HKEY_Key,0); 52 53 HKEY_Key="margin_bottom" 54 Wsh.RegWrite(HKEY_Root+HKEY_Path+HKEY_Key,0); 55 56 HKEY_Key="orientation" 57 Wsh.RegWrite(HKEY_Root+HKEY_Path+HKEY_Key,2); 58 59 } 60 catch(e) 61 {} 62 } 63 </script> 64 </html>
3、在你所要打印的页面加上打印的按钮,
<a id="btPrint" href="javascript:void(0)" title="打印报批件" onclick="printGroup();" class="linkbutton">【打 印】</a>
4、点击打印后会调用printGroup()方法，该方法写在同一文档的JS中
function printGroup() { openPrintDocument(groupId,"group"); }
function openPrintDocument(activityId,type) { window.open("../ForeignActivity/documentprint.aspx?a="+Math.random()+"&id="+activityId+"&type="+type,"",'width=820,height=750,left=50,top=50,menubar=yes,scrollbars=yes,resizable=yes,help=no,status=no;',true); }
5、这里所打开的documentprint.aspx文件也就是我们之前准备好的通用模版文件，在显示这个文件之前我们必须要获取另一个我们准备好的模版文件group_O_train.html，将这个文件追加到<div id="pPrintContent" runat="server">标签中
1）documentprint.aspx.cs 中 page_Load()中的代码：
1 protected void Page_Load(object sender, EventArgs e) 2 { 3 btprinttmember.Visible = false; 4 IPrintable print = new DocumentPrint(GetDocument()); 5 pPrintContent.InnerHtml = print.Print(); 6 7 }
2）在1)调用的GetDocument()方法获取文档
private IOutPutWithTemplate GetDocument() { IOutPutWithTemplate one=null; string type = GetDocumentTypeName(); type = type.ToLower(); switch (type) { case "rwpj": RWPJService service = new RWPJService(); one = service.GetByGroupId(Id); break; case "gfh": GFHService gfhService = new GFHService(); one = gfhService.GetByGroupId(Id); break; case "rwqrj": RWQRJService service2 = new RWQRJService(); one = service2.GetByGroupId(Id); break; case "zqyjfh": ZQYJFHService service3 = new ZQYJFHService(); one = service3.GetByGroupId(Id); break; case "groupwithsolution": //带审批意见的打印 GroupService gservice = new GroupService(); GZWGroupInfo group = (GZWGroupInfo)gservice.GetDetailGroupInfoById(Id); if (group.IsTrain) btprinttmember.Visible = true; one = new PrintApprovalSolutionDecorator(group); break; case "group": GroupService gservice2 = new GroupService(); GZWGroupInfo group2 = (GZWGroupInfo)gservice2.GetDetailGroupInfoById(Id); one = new PrintApprovalSolutionDecorator(group2); break; case "rwtzs": RWTZSService tzsService = new RWTZSService(); one = tzsService.GetById(Id); break; case "zqyjh": ZQYJHService yjhService = new ZQYJHService(); one = yjhService.GetById(Id); break; case "wth": WTHService wthService = new WTHService(); one = wthService.GetById(Id); break; case "hzk": HZKService hzkService = new HZKService(); one = hzkService.GetById(Id); break; case "cjzm": CJZMService cjzmService = new CJZMService(); one = cjzmService.GetOneById(Id); break; case "qzh": QZHService qzhService = new QZHService(); one = qzhService.GetById(Id); qzhService.FillChildren((QZH)one); break; case "ywzh": YWZHService ywzhService = new YWZHService(); one = ywzhService.GetById(Id); ywzhService.FillChildren((YWZH)one); break; case "pqh": PQHService pqhService = new PQHService(); one = pqhService.GetById(Id); pqhService.FillChildren((PQH)one); break; case "checkdrawbill": TicketReservation ticketReservation = new TicketReservationService().GetOneById(Id); one = new CheckDrawBillPrint(ticketReservation, "CheckDrawBill"); break; case "ticketpassportinfo": TicketReservation ticketReservation2 = new TicketReservationService().GetOneById(Id); one = new TicketPassportInfoPrint(ticketReservation2, "TicketPassportInfo"); break; case "ticketreservationprint": TicketReservation ticketReservation3 = new TicketReservationService().GetOneById(Id); one = new TicketReservationPrint(ticketReservation3, "TicketReservationPrint"); break; case "zsbackup": ZSInfo zsInfo = ZSService.GetById(Id); one = new ZSInfoPrint(zsInfo, "zsbackup"); break; //case "zsgroups": // GroupService SimpleGroupService = new GroupService(); // one = new ZSInfoGroupPrint((GZWGroupInfo)SimpleGroupService.GetSimpleGroupInfoById(Id)); // break; case "zspj": ZSPJ zspj = ZSPJService.GetByGroupId(Id); one = new ZSPJPrint(zspj, "zspj"); break; case "groupforapplypassport": //打印护照申办用的团组表 one = GroupPrint.CreateFromGroup(Id); break; case "unuploadplan": List<PlanBase> templists = new List<PlanBase>(); UnitInfo unitInfo = UnitService.GetUnitByCode(Profile.UnitCode); string plantype = Request.QueryString["planType"]; if (string.IsNullOrEmpty(plantype)) break; if (plantype.ToLower() == "general")//不含培训（包含汇总表打印和考察表打印） { List<PlanBase> hzlists = new List<PlanBase>(); PlanProcess process = new GeneralPlanProcess(); hzlists.AddRange(process.GetPlansByYear(unitInfo, Id, PlanType.ForUpload, PlanStatus.NotUploaded)); hzlists.AddRange(process.GetPlansByYear(unitInfo, Id, PlanType.ForUpload, PlanStatus.Retrial)); List<PlanBase> kclists = new List<PlanBase>(); kclists.AddRange(process.GetPlansByYearAndPurpose(unitInfo, Id, PlanType.ForUpload, PlanStatus.NotUploaded, "考察")); kclists.AddRange(process.GetPlansByYearAndPurpose(unitInfo, Id, PlanType.ForUpload, PlanStatus.Retrial, "考察")); GeneralPlanProcess gprocess = new GeneralPlanProcess(); for (int i = hzlists.Count - 1; i >= 0; i--) { GeneralPlan gp = hzlists[i] as GeneralPlan; //保存打印时间 gp.HzPrintTime = DateTime.Now; gprocess.SavePlan(gp); } foreach (PlanBase p in kclists) { GeneralPlan gp = (GeneralPlan)p; gp.KcPrintTime = DateTime.Now; gprocess.SavePlan(gp); } one = new PrintGeneralPlan(hzlists, kclists, Id, Profile.Name, Profile.Phone, "PrintGeneralPlan"); } else if (plantype.ToLower() == "sp")//审批 { PlanProcess processBySp = new SPPlanProcess(); templists.AddRange(processBySp.GetPlansByYear(unitInfo, Id, PlanType.ForUpload, PlanStatus.NotUploaded)); templists.AddRange(processBySp.GetPlansByYear(unitInfo, Id, PlanType.ForUpload, PlanStatus.Retrial)); //保存打印时间 foreach (PlanBase p in templists) { SPPlan sp = (SPPlan)p; sp.PrintTime = DateTime.Now; new SPPlanProcess().SavePlan(sp); } one = new PrintSPPlan(templists, Id, Profile.Name, Profile.Phone, "PrintSPPlan"); } else//审核 { PlanProcess processBySh = new SHPlanProcess(); templists.AddRange(processBySh.GetPlansByYear(unitInfo, Id, PlanType.ForUpload, PlanStatus.NotUploaded)); templists.AddRange(processBySh.GetPlansByYear(unitInfo, Id, PlanType.ForUpload, PlanStatus.Retrial)); //保存打印时间 foreach (PlanBase p in templists) { SHPlan sp = (SHPlan)p; sp.PrintTime = DateTime.Now; new SHPlanProcess().SavePlan(sp); } one = new PrintSHPlan(templists, Id, Profile.Name, Profile.Phone, "PrintSHPlan"); } break; case "plan": List<PlanBase> templist = new List<PlanBase>(); UnitInfo unit = UnitService.GetUnitByCode(Profile.UnitCode); string ptype = Request.QueryString["planType"]; if (string.IsNullOrEmpty(ptype)) break; if (ptype.ToLower() == "general")//不含培训（包含汇总表打印和考察表打印） { List<PlanBase> hzlists = new List<PlanBase>(); PlanProcess process = new GeneralPlanProcess(); hzlists.AddRange(process.GetPlansByYear(unit, Id, PlanType.ForUpload, PlanStatus.Uploaded)); hzlists.AddRange(process.GetPlansByYear(unit, Id, PlanType.ForUpload, PlanStatus.ReUploaded)); List<PlanBase> kclists = new List<PlanBase>(); kclists.AddRange(process.GetPlansByYearAndPurpose(unit, Id, PlanType.ForUpload, PlanStatus.Uploaded, "考察")); kclists.AddRange(process.GetPlansByYearAndPurpose(unit, Id, PlanType.ForUpload, PlanStatus.ReUploaded, "考察")); GeneralPlanProcess gprocess = new GeneralPlanProcess(); if (!Rules.CanManagerPlan()) { for (int i = hzlists.Count - 1; i >= 0; i--) { GeneralPlan gp = hzlists[i] as GeneralPlan; //保存打印时间 gp.HzPrintTime = DateTime.Now; gprocess.SavePlan(gp); } foreach (PlanBase p in kclists) { GeneralPlan gp = (GeneralPlan)p; gp.KcPrintTime = DateTime.Now; gprocess.SavePlan(gp); } } one = new PrintGeneralPlan(hzlists, kclists, Id, Profile.Name, Profile.Phone, "PrintGeneralPlan"); } else if (ptype.ToLower() == "sp")//审批 { PlanProcess processBySp = new SPPlanProcess(); templist.AddRange(processBySp.GetPlansByYear(unit, Id, PlanType.ForUpload, PlanStatus.Uploaded)); templist.AddRange(processBySp.GetPlansByYear(unit, Id, PlanType.ForUpload, PlanStatus.ReUploaded)); if (!Rules.CanManagerPlan()) { //保存打印时间 foreach (PlanBase p in templist) { SPPlan sp = (SPPlan)p; sp.PrintTime = DateTime.Now; new SPPlanProcess().SavePlan(sp); } } one = new PrintSPPlan(templist, Id, Profile.Name, Profile.Phone, "PrintSPPlan"); } else//审核 { PlanProcess processBySh = new SHPlanProcess(); templist.AddRange(processBySh.GetPlansByYear(unit, Id, PlanType.ForUpload, PlanStatus.Uploaded)); templist.AddRange(processBySh.GetPlansByYear(unit, Id, PlanType.ForUpload, PlanStatus.ReUploaded)); if (!Rules.CanManagerPlan()) { //保存打印时间 foreach (PlanBase p in templist) { SHPlan sp = (SHPlan)p; sp.PrintTime = DateTime.Now; new SHPlanProcess().SavePlan(sp); } } one = new PrintSHPlan(templist, Id, Profile.Name, Profile.Phone, "PrintSHPlan"); } break; case "qzxxb": QZSXB qzsxb = QZSXBService.GetQZSXBById(Id); //one = QZSXBService.Print(docID); one = new QZXXBPrint(qzsxb); break; case "qzxxbmember": QZSXBMember qzsxbMember = QZSXBService.GetMemberById(Id); one = new QZXXBMemberPrint(qzsxbMember); break; case "qzxxbcountry": QZSXBCountry qzsxbCountry = QZSXBService.GetCountryById(Id); one = new QZXXBCountryPrint(qzsxbCountry); break; case "chinesenote": one = new ChineseNoteService().GetById(Id); break; } return one; }
3) 在2）中调用GetDocumentTypeName()方法获取文档类型，类弄为“group”
private string GetDocumentTypeName() { return Request.Params["type"]; }
4） 在2）中调用GetDetailGroupInfoById(Id)方法，根据ID号获取到Group表的数据
5） 在2）中调用PrintApprovalSolutionDecorator(group2)方法是对这些数据进行处理，也就是去填充模版
在这个类中首先要确定这个模版文件的名称，这里确定的是group_O_train.html文件
6）读文件
/// <summary> /// 按照对象的类型名称来获取模版,规则是打开 对象类型名称.html文件,读取其中的内容 /// </summary> /// <param name="type">类型名称(字符串,比如:group,budget)</param> /// <returns></returns> static public string GetTemplateFromFile(string type) { string fileName = HttpContext.Current.Server.MapPath("../Template/" +type+ ".html"); return ReadTemplateFromFile(fileName); } /// <summary> /// 读取文件 /// </summary> /// <param name="fileName"></param> /// <returns></returns> static private string ReadTemplateFromFile(string fileName) { if (!File.Exists(fileName)) { throw new ApplicationException(fileName + "不存在"); } System.Text.StringBuilder rtn = new System.Text.StringBuilder(); using (StreamReader sr = File.OpenText(fileName)) { String input; while ((input = sr.ReadLine()) != null) { rtn.Append(input); } sr.Close(); } return rtn.ToString(); }
7）在1）中调用Print()方法是它会去调OutPut(string template)方法
string IPrintable.Print() { return document.OutPut(this.Template); }
OutPut(string template)方法是IOutPutWithTemplate的一个接口
8)在类PrintApprovalSolutionDecorator中实现了OutPut(string template)方法，在这个方法中对模版文件中的占位符进行了替换
9）在1)中pPrintContent.InnerHtml = print.Print();就是将group_O_train.html追加到DocumentPrint.aspx中，最后将DocumentPrint.aspx页面展示出来，也就是我们要打印的页面。
