本文是asp.net Gridview操作小積累，用得着的可以參考一下，本例子思想來源於webcast
前臺關鍵代碼：
<asp:GridView ID="GridView1" runat="server">
</asp:GridView>
<asp:Button ID="butExport" runat="server" Text="Export"
οnclick="butExport_Click" />
後臺關鍵代碼：
protected void butExport_Click(object sender, EventArgs e)
{
Response.Clear();//清除緩衝區所有內容，防止影響導入到excel的數據
Response.Buffer = true; //response緩存
Response.Charset = "GB2312"; //設置輸出流字符集
Response.AppendHeader("Content-Disposition","attachment;filename="+@"d:/person.xls"); //設置excel存放路徑
//如果設置GetEncoding(“GB2312”)可能會出現亂碼問題
Response.ContentEncoding = System.Text.Encoding.UTF8;
//設置爲excel文件輸出
Response.ContentType = "application/ms-excel";
System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter oHtmlWriter = new HtmlTextWriter(oStringWriter);
this.GridView1.RenderControl(oHtmlWriter);
Response.Output.Write(oStringWriter.ToString());
Response.Flush();
Response.End();
}
//下面類必須重寫，否則運行時會報錯
public override void VerifyRenderingInServerForm(Control control)
{
//base.VerifyRenderingInServerForm(control);
}
