解決方案：
頁面增加一個按鈕，單擊事件添加如下方法：
protected void Button1_Click(object sender, EventArgs e)
{
Export("application/ms-excel", "學生成績報表.xls");
}
private void Export(string FileType, string FileName)
{
Response.Charset = "GB2312";
Response.ContentEncoding = System.Text.Encoding.UTF7;
Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(FileName, Encoding.UTF8).ToString());
Response.ContentType = FileType;
this.EnableViewState = false;
StringWriter tw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(tw);
GridView1.RenderControl(hw);
Response.Write(tw.ToString());
Response.End();
}
//如果沒有下面方法會報錯類型“GridView”的控件“GridView1”必須放在具有 runat=server 的窗體標記內
public override void VerifyRenderingInServerForm(Control control)
{
}
