用savefiledialog控件

savefiledialog.showdialog();

那如何在出来的另存为对话框中，下面的扩展名出现“excel文档”，就是直接以excel形式保存？

[angelswings]

savefiledialog.Filter=excel文档(*.xls)|*.xls;

DataGrid1.AllowPaging =false;
Response.Clear();
Response.Buffer= true;
Response.Charset="GB2312";
Response.AppendHeader("Content-Disposition","attachment;filename=HelloAdmin.xls");
Response.ContentEncoding=System.Text.Encoding.GetEncoding("GB2312");//设置输出流为简体中文
Response.ContentType = "application/ms-excel";//设置输出文件类型为excel文件。
this.EnableViewState = false;
System.Globalization.CultureInfo myCItrad = new System.Globalization.CultureInfo("ZH-CN",true);
System.IO.StringWriter oStringWriter = new System.IO.StringWriter(myCItrad);
System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
this.DataGrid1.RenderControl(oHtmlTextWriter);
Response.Write(oStringWriter.ToString());
Response.End();

DataGrid1.AllowPaging =true;
在asp.net里是这样的从datagrid里下载
