DOWNLOAD 文件

 FileStream MyFileStream; 
 long FileSize; 
  
 MyFileStream = new FileStream=("c:\\a.doc",FileMode.Open); 
 FileSize = MyFileStream.Length; 
       
 byte[] Buffer = new byte[(int)FileSize]; 
 MyFileStream.Read(Buffer, 0, (int)FileSize); 
 MyFileStream.Close(); 
  
 Response.AddHeader("Content-Disposition", "attachment;filename="c:\\a.doc"); 
 Response.ContentType="application/octet-stream"; 
 
 Response.BinaryWrite(Buffer); 

 

运行，IE出现打开、下载文件的对话框。但是如果选择直接打开，Word却打不文件。 
试了几次都不行，还以为是2003安全性的问题。 
后来想到ASP.NET缓存，于是加了两行代码 
   Response.Flush(); 
   Response.Close(); 
结果OK。
