2、IMEX=1; /Sql语句 stringstrExcel=select*from+strSheetName+$; DataSetds=newDataSet(); /连接数据源 OleDbConnectionconn=newOleDbConnection(strConn); conn.Open(); /适配到数据源 OleDbDataAdapteradapter=newOleDbDataAdapter(strExcel,conn); adapter.Fill(ds,data); conn.Close(); GridView1.DataSource=ds.Tablesdata; GridView
3、1.DataBind(); Label1.Text=ds.Tables0.Rows.Count.ToString(); SqlAccess.Sqldatabasesql=newSqlAccess.Sqldatabase(); StringBuildersb=newStringBuilder(); for(inti=0;ids.Tables0.Rows.Count;i+) sb.Append(insertintodatavalues(+ds.Tables0.Rowsicompanyname+,+ds.Tables0.Rowsitelname+,+ds.Tables0.Rowsiqytel+,+d

7、 e) #region 变量 bool style = false; string Road = ; #endregion #region 文件上传 try string ExcelFile = this.FileUpload.PostedFile.FileName;/FileUpload为asp:FileUpload控件 string FileName = ExcelFile.Substring(ExcelFile.LastIndexOf(.) + 1); if (FileName != xls) Response.Write(alert(您上传的不是Excel文件！); return; #
8、region 设置上传路径奖文件保存到服务器 string datetime = DateTime.Now.Date.ToString(yyyyMMdd); string time = DateTime.Now.ToShortTimeString().Replace(:, ); string NewFileName = Excel + datetime + time + DateTime.Now.Millisecond.ToString() + .xls;/生成新文件名 Road = Server.MapPath(.Update) + + NewFileName; this.FileUploa
9、d.PostedFile.SaveAs(Road); #endregion catch Response.Write(alert(数据上传失败，请重新导入); return; #endregion #region 数据导入 try #region 变量 StormCIS.BLL.WorkCenter_StudentInfo bll = new StormCIS.BLL.WorkCenter_StudentInfo(); string titlename = 教师职工号, 教师姓名, 教师性别, 出生日期, 学历, 联系电话 ; DataSet ds = bll.ExcelTables(Road); #endregion #region 检验表格数据 for (int i = 0; i ds.Tables.Count; i+)
