Use response. binarywrite to write a file stream

There have been many things recently and I have never written anything.

Write a stream to the client a few days ago Code :

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 );

Run. The IE dialog box opens and downloads the file. However, if you choose to open the file directly, the Word file is not used.

I tried it several times and thought it was a 2003 security issue.

Later I thought of ASP. NET cache, so I added two lines of code.

Response. Flush ();

Response. Close ();

The result is OK.
