嗨Mahesh

在我的代码中编写一个查询，用于选择所需的值并将其导出到excel。

  string  str =  您的查询; 
 ds = da.fill_data（str）; 
 DataTable dt =  new  DataTable（）; 
 dt = ds.Tables [ 0 ]; 
 string  attachment =   attachment; filename = ABC.xls跨度>; 
 Response.ClearContent（）; 
 Response.AddHeader（  content-disposition，附件）; 
 Response.ContentType =   application / vnd.ms-excel; 
 string  tab =  ; 
 foreach （DataColumn dc  in  dt.Columns）
 {
 Response.Write（tab + dc.ColumnName）; 
 tab =   \t; 
} 
 Response.Write（  \ n）; 
 int  i; 
 foreach （DataRow dr  in  dt.Rows）
 {
 tab =  ; 
 for （i =  0 ; i < ;  dt.Columns.Count; i ++）
 {
 Response.Write（tab + dr [i] .ToString（））; 
 tab =   \t; 
} 
 Response.Write（  \ n）; 
} 
 Response.End（）; 

作为答案，如果它可以帮助你。

或者你可以使用EPPLUS

你可以制作一个通用的方法来检索数据源

并将其用于网格生成和excel生成

EPPLUS示例：

i认为它非常容易使用，并且不太容易出现兼容性错误，从xml /创建excel HTML

when export to excel the excel file contains the hidden column from gridview.

i explain it deeply.

In GridView I hide the 3rd column and export to excel.

in excel file I need the "C" column with hidden.

Hi Mahesh
In my code write a query for picking values which you want and export them to excel.

string str = "your Query";
           ds = da.fill_data(str);
           DataTable dt = new DataTable();
           dt = ds.Tables[0];
           string attachment = "attachment; filename=ABC.xls";
           Response.ClearContent();
           Response.AddHeader("content-disposition", attachment);
           Response.ContentType = "application/vnd.ms-excel";
           string tab = "";
           foreach (DataColumn dc in dt.Columns)
           {
               Response.Write(tab + dc.ColumnName);
               tab = "\t";
           }
           Response.Write("\n");
           int i;
           foreach (DataRow dr in dt.Rows)
           {
               tab = "";
               for (i = 0; i < dt.Columns.Count; i++)
               {
                   Response.Write(tab + dr[i].ToString());
                   tab = "\t";
               }
               Response.Write("\n");
           }
           Response.End();

make as answer if it helps You.

there are articles like that

or you can use EPPLUS
you can make a generic method to retrieve the datasource
and use it both for grid generation and excel generation
EPPLUS Example :

i think it is quite symple to use and less prone to compatibility error that creating excel from the xml/html
