net3.5 Gridview 数据导出到Excel

[sdudubing]

我用的是VS2008开发的，我电脑上安装的Excel是2007版。网上也有相关的代码，但应用到我程序中出现错误：
如导出文件名是乱码：
打开时提示错误：

我的相关代码如下：
public static void ToExcel(Control ctl, string FileName)
{
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.Buffer = true;
HttpContext.Current.Response.Charset = "GB2312";
HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.Default;
HttpContext.Current.Response.ContentType = "application/ms-excel";
HttpContext.Current.Response.AppendHeader("Content-Disposition", "attachment;filename=" + "" + FileName+".xls");
// HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.UTF7;
ctl.Page.EnableViewState = false;
System.IO.StringWriter tw = new System.IO.StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(tw);
ctl.RenderControl(hw);
HttpContext.Current.Response.Output.Write(tw.ToString());
HttpContext.Current.Response.Flush();
HttpContext.Current.Response.End();
}
public override void VerifyRenderingInServerForm(Control control)
{

}

帮我看看哪里有问题？大家有更适用代码的可以分享？

参考

 public static void DataTable2Excel(System.Data.DataTable dtData)
        {
            System.Web.UI.WebControls.DataGrid dgExport = null;
            // 当前对话 
            System.Web.HttpContext curContext = System.Web.HttpContext.Current;
            // IO用于导出并返回excel文件 
            System.IO.StringWriter strWriter = null;
            System.Web.UI.HtmlTextWriter htmlWriter = null;

            if (dtData != null)
            {
                // 设置编码和附件格式 
                curContext.Response.ContentType = "application/vnd.ms-excel";
                curContext.Response.ContentEncoding = System.Text.Encoding.GetEncoding("gb2312");
                curContext.Response.Charset = "";

                // 导出excel文件 
                strWriter = new System.IO.StringWriter();
                htmlWriter = new System.Web.UI.HtmlTextWriter(strWriter);

                // 为了解决dgData中可能进行了分页的情况，需要重新定义一个无分页的DataGrid 
                dgExport = new System.Web.UI.WebControls.DataGrid();
                dgExport.DataSource = dtData.DefaultView;
                dgExport.AllowPaging = false;
                dgExport.DataBind();

                // 返回客户端 
                dgExport.RenderControl(htmlWriter);
                curContext.Response.Write(strWriter.ToString());
                curContext.Response.End();
            }
        }

度娘，Myxls

你这个导出局限性太大！
