在SharePoint 上实现SPGridView导出到Excel

以下是导出方法：
 1 public static void Export(string fileName, SPGridView gv)
 2         {
 3             
 4             HttpContext.Current.Response.Clear();
 5             HttpContext.Current.Response.Buffer = true;
 6             HttpContext.Current.Response.Write("<meta http-equiv=Content-Type content=text/html;charset=UTF-8>");
 7             HttpContext.Current.Response.ContentType = "application/vnd.ms-excel";
 8             HttpContext.Current.Response.AddHeader(
 9                 "content-disposition", string.Format("attachment; filename={0}", fileName.Replace(" ","_")));
10             HttpContext.Current.Response.Charset = "UTF-8";
11             HttpContext.Current.Response.HeaderEncoding = Encoding.UTF8;
12             HttpContext.Current.Response.ContentEncoding = Encoding.UTF8;
13 
14             using (StringWriter sw = new StringWriter())
15             {
16                 using (HtmlTextWriter htw = new HtmlTextWriter(sw))
17                 {
18                     Table table = new Table();
19 
20                     gv.HeaderRow.Cells[0].Visible = false;
21                     gv.FooterRow.Cells[0].Visible = false;
22 
23                     if (gv.HeaderRow != null)
24                     {
25                         GridViewExportUtil.PrepareControlForExport(gv.HeaderRow);
26                         table.Rows.Add(gv.HeaderRow);
27                     }
28

30                     {
31                         GridViewExportUtil.PrepareControlForExport(row);
32                         row.Cells[0].Visible = false;
33                         table.Rows.Add(row);
34                     }
35 
36                     if (gv.FooterRow != null)
37                     {
38                         GridViewExportUtil.PrepareControlForExport(gv.FooterRow);
39                         table.Rows.Add(gv.FooterRow);
40                     }
41 
42                     table.RenderControl(htw);
43 
44                     HttpContext.Current.Response.Write(sw.ToString());
45                     HttpContext.Current.Response.End();
46                 }
47             }
48         }
49 
50         private static void PrepareControlForExport(Control control)
51         {
52             for (int i = 0; i < control.Controls.Count; i++)
53             {
54                 Control current = control.Controls[i];
55                 if (current is LinkButton && current.Visible)
56                 {
57                     control.Controls.Remove(current);
58                     control.Controls.AddAt(i, new LiteralControl((current as LinkButton).Text));

65                 else if (current.Visible == false)
