Asp.net导入Excel数据文件
实现页面选择查找文件，并导入以如下结构为模板的Excel数据文件
前台设计界面如下：
在这里使用asp.net的FileUpload控件实现文件查找选择，前台代码如下：
<html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title></title> <base target="_self" /> </head> <body style="height: 380px; width: 1000px; background-color: #B9D3EE;"> <form id="form1" runat="server"> <div style="margin-top: 50px; margin-left: 50px;"> <div style="height: 38px"> <asp:Label runat="server" Text="文件*：" Width="60px"></asp:Label> <asp:FileUpload ID="fulImport" runat="server" Height="20px" Width="450px" /> </div> <div style="height: 68px; margin-top: 60px;"> <div style="float: left; margin-left: 85px"> <asp:Button ID="btnImport" runat="server" Text="上传" Width="60px" Height="30px" OnClick="btnImport_Click" /> </div> <div style="float: left; margin-left: 60px"> <asp:Button ID="btnClose" runat="server" Text="关闭" Width="60px" Height="30px" OnClick="btnClose_Click" /> </div> </div> </div> </form> </body> </html>
选择文件后点击上传按钮触发后台点击事件。
/// <summary> /// 上传导入按钮点击 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> protected void btnImport_Click(object sender, EventArgs e) { try { //文件名 string strFileName = fulImport.FileName; //验证是否选择了文件 if ("" == strFileName.Trim()) { ScriptManager.RegisterStartupScript(this, this.GetType(), "JsError", "alert('请选择文件！');", true); return; } //验证文件类型是不是Excel if (strFileName.Substring(strFileName.LastIndexOf('.')) != ".xlsx" && strFileName.Substring(strFileName.LastIndexOf('.')) != ".xls") { ScriptManager.RegisterStartupScript(this, this.GetType(), "JsError", "alert('文件类型错误！'", true); return; } //获取上载文件内容 string Attachment = "";//附件 //string strFilePath = ConfigurationManager.AppSettings["tempFilePath"].ToString(); string strFilePath = "./tem/"; strFilePath = Server.MapPath(strFilePath); Attachment = fulImport.funString_FileUpLoadAttachmentABPath(strFileName, 50, strFilePath); string strPath = strFilePath + Attachment; fulImport.PostedFile.SaveAs(strPath); DataSet ds = GetExcelData(strPath); //判断文件内容是否为空 if (ds == null) { ScriptManager.RegisterStartupScript(this, this.GetType(), "JsError", "alert('这个文件没有数据！');", true); return; } int i_count = 0;//计算行数 IdioSoft.Common.Method.DbSQLAccess objDbSQLAccess = new IdioSoft.Common.Method.DbSQLAccess(SqlCon); //导入到数据库 try { int result = 0; foreach (DataTable dt in ds.Tables) { try { string strRow = dt.Rows[0]["工厂"].ToString();//判断行是否存在 } catch (Exception) { continue; } //行数存在,累加行数 i_count++; string strFactory = ""; string strWorkshop = ""; string strQualityDoor = ""; string strFirstPartStructure = ""; string strSecondPartStructure = ""; for (int i = 0; i < dt.Rows.Count; i++) { strFactory = dt.Rows[i]["工厂"].ToString(); strWorkshop = dt.Rows[i]["车间"].ToString(); strQualityDoor = dt.Rows[i]["质量门"].ToString(); strFirstPartStructure = dt.Rows[i]["一级零部件结构"].ToString(); strSecondPartStructure = dt.Rows[i]["二级零部件结构"].ToString(); //判断行数据是否完整并给出提示 if (strFactory == "" || strWorkshop == "" || strQualityDoor == "" || strFirstPartStructure == "" || strSecondPartStructure == "") { int m = i + 1; ScriptManager.RegisterStartupScript(this, this.GetType(), "JsError", "alert('第" + m + "行数据不完整！')", true); return; } else//数据完整则插入数据库 { string strSqlDelete = string.Format(@" DELETE FROM [Test].[dbo].[QMS_QualiryDoorAndParts] WHERE [Factory]=N'{0}' AND [Workshop]=N'{1}' AND [QualityDoor]=N'{2}' AND [FirstPartStructure]=N'{3}' AND [SecondPartStructure]=N'{4}' ", strFactory, strWorkshop, strQualityDoor, strFirstPartStructure, strSecondPartStructure); objDbSQLAccess.funString_SQLExecuteScalar(strSqlDelete); string strSqlInsert = string.Format(@" INSERT INTO [Test].[dbo].[QMS_QualiryDoorAndParts] ([Factory] ,[Workshop] ,[QualityDoor] ,[FirstPartStructure] ,[SecondPartStructure]) VALUES (N'{0}' ,N'{1}' ,N'{2}' ,N'{3}' ,N'{4}') ",strFactory ,strWorkshop ,strQualityDoor,strFirstPartStructure, strSecondPartStructure); result = objDbSQLAccess.funString_SQLExecuteScalar(strSqlInsert).funInt_StringToInt(0); } } } if (result == 0 && i_count > 0) { ScriptManager.RegisterStartupScript(this, this.GetType(), "JsError", "alert('导入成功。');", true); } else if (i_count == 0) { ScriptManager.RegisterStartupScript(this, this.GetType(), "JsError", "alert('EXEC中的列名不符合规则。');", true); } } catch (Exception ex) { ScriptManager.RegisterStartupScript(this, this.GetType(), "JsError", "alert('Fail:" + ex.Message + "');", true); } } catch (Exception exp) { ScriptManager.RegisterStartupScript(this, this.GetType(), "JsError", "alert('Fail:" + exp.Message + "');", true); } }
后台完整实现代码如下：
