导出Excel,文件名乱码(直接另存或下载为不会乱码,直接打开文件名乱码)

private void DataTable3Excel(System.Data.DataTable dtData, String FileName)
{
System.Web.UI.WebControls.GridView 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
        //System.Web.HttpUtility.UrlEncode(FileName, System.Text.Encoding.UTF8)作用是方式中文文件名乱码"中文文件名"
        curContext.Response.AddHeader("content-disposition", "attachment;filename=" + System.Web.HttpUtility.UrlEncode(FileName, System.Text.Encoding.UTF8) + ".xls");
        curContext.Response.ContentType = "application nd.ms-excel";
        curContext.Response.ContentEncoding = System.Text.Encoding.UTF8;
        curContext.Response.Charset = "GB2312";

        //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GridView
        dgExport = new System.Web.UI.WebControls.GridView();
        dgExport.DataSource = dtData.DefaultView;
        dgExport.AllowPaging = false;
        dgExport.DataBind();

        //下载到客户端
        dgExport.RenderControl(htmlWriter);
        curContext.Response.Write(strWriter.ToString());
        curContext.Response.End();
    }
}
