Response.Clear();
2 Response.Buffer = true;
3 Response.Charset = "GB2312";
4 Response.AppendHeader("Content-Disposition", "attachment;filename=jtkc.xls");
5 Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");//设置输出流为简体中文
6 Response.ContentType = "application/ms-excel";//设置输出文件类型为excel文件。
7 this.EnableViewState = false;
8 System.Globalization.CultureInfo myCItrad = new System.Globalization.CultureInfo("ZH-CN", true);
9 System.IO.StringWriter oStringWriter = new System.IO.StringWriter(myCItrad);
10 System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
11 grvExcel.RenderControl(oHtmlTextWriter);
12 Response.Write(oStringWriter.ToString());
13 Response.End();
Response.Clear();2
Response.Buffer = true;3

this.EnableViewState = false;8
System.Globalization.CultureInfo myCItrad = new System.Globalization.CultureInfo("ZH-CN", true);9
System.IO.StringWriter oStringWriter = new System.IO.StringWriter(myCItrad);10
System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);11

1.这过程中遇到一些问题，刚开始是提示GridView必须放在runat="server"的窗体中，但是
只需要重写VerifyRenderingInServerForm方法，将内容清空就可以了。

}
2。第二个问题是提示：只能在 Render(); 期间呼叫 RegisterForEventValidation
这个问题比较好解决，只需要在前台页面的@Page指令中加上一个属性：EnableEventValidation="false"
