if(!System.IO.File.Exists(strFile))
{
Response.Write("<script language='javascript'>alert('对不起，文件不存在！');</script>");
return;
}
Response.Clear();
Response.ClearHeaders();
Response.Charset = "GB2312";
Response.ContentEncoding =System.Text.Encoding.UTF8;
Response.ContentType = "application/octet-stream"; 
FileInfo fi=new FileInfo(strFile);
Response.AddHeader("Content-Disposition","attachment; filename="  +  HttpUtility.UrlEncode(fi.Name));
Response.AddHeader("Content-Length",fi.Length.ToString());
byte[] tmpbyte=new byte[1024*8];
FileStream fs=fi.OpenRead();
int count;
while((count=fs.Read(tmpbyte,0,tmpbyte.Length))>0)
{
Response.BinaryWrite(tmpbyte);
