public static void GenerateByGridView(string Typename, GridView TempGrid)
{
HttpContext.Current.Response.Clear();
//HttpContext.Current.Response.Buffer = true;
HttpContext.Current.Response.Charset = "utf-8 ";
string Filename = Typename + ".xls ";
HttpContext.Current.Response.AppendHeader( "Content-Disposition ", "online;filename= " + Filename);
HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.GetEncoding( "utf-8 ");
HttpContext.Current.Response.ContentType = "application/ms-excel ";
//this.EnableViewState = false;
System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
TempGrid.RenderControl(oHtmlTextWriter);
HttpContext.Current.Response.Write(oStringWriter.ToString());
HttpContext.Current.Response.End();
}

Typename 为文件名
