  • 将dataset导出excel文件

      public static DataSet Query(string SQLString)
           {
               using (SqlConnection connection = new SqlConnection(ConnectionString))
               {
                   DataSet ds = new DataSet();
                   try
                   {
                       connection.Open();
                       SqlDataAdapter command = new SqlDataAdapter(SQLString, connection);
                       command.Fill(ds, "ds");
                   }
                   catch (System.Data.SqlClient.SqlException ex)
                   {
                       throw new Exception(ex.Message);
                   }
                   return ds;
               }
           }

    上面代码为执行SQL语句,反回dataset类型出来

     DataSet ds = Pagin.Query(strsql);
       public void EasyExportExcel(HttpResponse resp)
            {
                resp.Charset = "gb2312";
                resp.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");
    
                resp.AppendHeader("Content-Disposition", "attachment;filename=" + FileName + ".xls");
                resp.ContentType = "applicationnd.ms-excel";
    
                string herd = "<meta http-equiv=\"content-type\" content=\"application/ms-excel; charset=GB2312\"/>";
    
                StringBuilder table = new StringBuilder();
                table.Append("<table border='1'>");
    
                #region 设置表头
    
                table.Append("<tr>");
    
                for (int i = 0; i < this.Data.Columns.Count; i++)
                {
                    table.Append("<th>" + this.Data.Columns[i].ColumnName + "</th>");
                }
    
                table.Append("</tr>");
    
                #endregion
    
                table.Append("</table>");
    
                resp.Write(herd + table);
                resp.Flush();
                resp.End();
            }
    export.EasyExportExcel(this.Response);

    即可导出 EXCEL
