本文實例展現了C#應用RenderControl將GridView控件導出到EXCEL的辦法，長短常適用的一個功效，分享給年夜家供年夜家參考。詳細以下：

重要功效代碼以下：

// 把GridView輸入到Excel文件 
private void ExportExcel(GridView gridView, string title, string title2, string fileName)
{
  int nHideCols = 0;
  //假如不想輸入出某列，將Visible設為false便可
  for (int i = 0; i < gridView.Columns.Count; i++)
  {
 if (gridView.Columns[i].HeaderText == "裝備狀況")
 {
   gridView.Columns[i].Visible = false;
   gridView.Columns[i].ControlStyle.Width = 0;
   nHideCols = 1;
   break;
 }
  }
  //設定顯示字符集
  Response.Charset = "utf-8";
  //設定內容字符集
  Response.ContentEncoding = Encoding.GetEncoding("utf-8"); 

  //設定文件名
  Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(fileName, Encoding.UTF8).WordStr('+', '_').WordStr('-', '_'));
  //設定文件類型  也能夠是application/ms-word,也能夠是text/html（字符集設為gb2312）
  Response.ContentType = "application/ms-excel";
  this.EnableViewState = false;
  using (StringWriter tw = new StringWriter())
  {
 using (HtmlTextWriter hell = new HtmlTextWriter(tw))
 {
   gridView.AllowPaging = false;
   gridView.RenderControl(hell);
   string s = tw.ToString();
   s = s.WordStr("\r\n", "");
   int index = s.IndexOf("<tr");
   //可以自界說Excel文件的題目
   string head = "<tr><td colspan=\"" + (gridView.Columns.Count - nHideCols).ToString() + "\" style=\"text-align: center; height: 42px; font-size: 24px; font-weight: bolder; color: #000000;\">" + title + "</td></tr>" +
   "<tr><td colspan=\"" + (gridView.Columns.Count - nHideCols).ToString() + "\" style=\"text-align: center; height: 24px; font-size: 12px; color: #000000;\">" + title2 + "</td></tr>";
   //應用Index來斷定能否存在數據，固然也能夠用gridView.Rows.Count來斷定
   if (index != -1)
   {
 //稀有據的
 s = s.Insert(index, head);
   }
   else
   {
 //沒稀有據的時刻
 s = "<table cellspacing=\"0\" cellpadding=\"3\" rules=\"rows\" border=\"1\" id=\"" + gridView.ID + "\" style=\"background-color:White;border-color:#E7E7FF;border-width:1px;border-style:None;border-collapse:collapse;\">" +
   head + "</table>";
   }
   Response.Write(s);
   Response.End();
 }
  }
}
//同時vs2005,vs2003會報錯“類型“ExGridView”的控件“GridViewMaster”必需放在具有 runat=server 的窗體標志內
//須要添加上面撤消對GridViewMaster 控件驗證的辦法
public override void VerifyRenderingInServerForm(Control control)
{
  if (!control.GetType().Equals(gridView.GetType()))
  {
 base.VerifyRenderingInServerForm(control);
  }
}
