放置一个按钮,添加click代码,强制下载..如下:

protected void Button1_Click(object sender, EventArgs e)
{
//========不从缓存拿数据,直接下载服务器文件====================
string destFileName = Server.MapPath("file/" + this.Label1.Text.ToString().Trim());
FileInfo fi = new FileInfo(destFileName);
Response.Clear();
Response.ClearHeaders();
Response.Buffer = false;
Response.AppendHeader("Content-Disposition", "attachment;filename=" + Server.UrlEncode(Path.GetFileName(destFileName)));
Response.AppendHeader("Content-Length", fi.Length.ToString());
Response.WriteFile(destFileName);
Response.Flush();
Response.End();

}

=================

将this.Label1.Text.ToString().Trim()改成你的文件名就可以了
