学习总结——c#生成word文档

主要就是首先制作一个模板，生成过程中主要进行替换：

        public static void prepareword_hz(string htid)
        {
            //贷款申请信息获得

            HttpServerUtility _server = HttpContext.Current.Server;
            string TemplateFile = _server.MapPath("~\\basedatas\\huizhi.doc");

            string idname = htid + "hz.doc";
            string fname = "~\\doctemp\\" + idname;
            string FileName = _server.MapPath(fname);
            object Obj_FileName = FileName;
            
            //保存

            File.Copy(TemplateFile, FileName, true);
            object Visible = false;
            object ReadOnly = false;
            object Missing = System.Reflection.Missing.Value;
            Microsoft.Office.Interop.Word.ApplicationClass wordapp = new Microsoft.Office.Interop.Word.ApplicationClass();//定义word应用程序        
            
            //打开文件
            Microsoft.Office.Interop.Word._Document wd = wordapp.Documents.Open(ref Obj_FileName, ref Missing,
            ref ReadOnly, ref Missing,
            ref Missing, ref Missing,
            ref Missing, ref Missing,
            ref Missing, ref Missing,
            ref Missing, ref Visible,
            ref Missing, ref Missing,
            ref Missing, ref Missing);

            wd.Activate();
            //定义替换类型为替换发现的第一个
            object replaceAll = Microsoft.Office.Interop.Word.WdReplace.wdReplaceAll;

            wordapp.Selection.Find.ClearFormatting();
            wordapp.Selection.Find.Replacement.ClearFormatting();
            wordapp.Selection.Find.Wrap = WdFindWrap.wdFindContinue;
            wordapp.Selection.Find.Forward = true;

            BLLibrary.Bdk_hetong dkhetongdal = new Bdk_hetong();
            Model.dk_hetongEntity dkhetong = new dk_hetongEntity();
            dkhetong = dkhetongdal.Getdk_hetong(Convert.ToInt32(htid));

            wordapp.Selection.Find.Text = "$sq_year";
            wordapp.Selection.Find.Replacement.Text = System.DateTime.Today.Year.ToString();
            wordapp.Selection.Find.Execute(ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref replaceAll, ref Missing, ref Missing, ref Missing, ref Missing);
            //年度，"$sq_year"为在模板中设定的特定符号

            wordapp.Selection.Find.Text = "$jk_name";
            wordapp.Selection.Find.Replacement.Text = dkhetong.jk_name.ToString();
            wordapp.Selection.Find.Execute(ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref replaceAll, ref Missing, ref Missing, ref Missing, ref Missing);
            //学生姓名
            
            wordapp.Selection.Find.Text = "$shi";
            BLLibrary.Bcode_dw dwdal = new Bcode_dw();
            Model.code_dwEntity dw = new code_dwEntity();
            dw = dwdal.Getcode_dw(dkhetong.shi);
            wordapp.Selection.Find.Replacement.Text = dw.dwname.ToString();
            wordapp.Selection.Find.Execute(ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref replaceAll, ref Missing, ref Missing, ref Missing, ref Missing);
            //市

            wordapp.Selection.Find.Text = "$xian";
            dw = dwdal.Getcode_dw(dkhetong.xian);
            wordapp.Selection.Find.Replacement.Text = dw.dwname.ToString();
            wordapp.Selection.Find.Execute(ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref replaceAll, ref Missing, ref Missing, ref Missing, ref Missing);
            //县

            // 保存word文档

            wd.SaveAs(ref Obj_FileName, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing);

            // 关闭，释放

            wd.Close(ref Missing, ref Missing, ref Missing);

            wordapp.Quit(ref Missing, ref Missing, ref Missing);

            wd = null;
            if (wordapp != null)
            {
                wordapp = null;
            }
            //wordapp = null;
            //GC.Collect(); 

            //下载文档
            HttpContext.Current.Response.Redirect("~/doctemp/downword.aspx?id=" + idname);

        }

 下载：

namespace sydweb.doctemp
{
    public partial class downword : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            string FullFileName = Request.QueryString["id"];

            FileInfo DownloadFile = new FileInfo(HostingEnvironment.ApplicationPhysicalPath + "doctemp\\" + FullFileName); // 需要转换为绝对路径，否则会自动认到C盘系统里那个IIS目录下面去，而且，无法通过URI的方式来进行数据流读取。如果你生成的文件不在web目录下，也需要明确指出。  

            // 下面到就是读取文件，通过数据流的方式下载了。

            Response.Clear();

            Response.ClearHeaders();

            Response.Buffer = false;

            Response.ContentType = "application/octet-stream";

            Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(FullFileName, System.Text.Encoding.UTF8));

            Response.AppendHeader("Content-Length", DownloadFile.Length.ToString());

            Response.WriteFile(DownloadFile.FullName);

            Response.Flush();

            Response.End();
        }
    }
