流被关闭仍然出错为什么？ [英] stream is closed get still error why?

问题描述

该进程无法访问文件''C：\inetpub \wwwroot \wss \ VirtualDirectories \ 80 \ Upload \ _mydoc_2013-05-03.doc''，因为它正在被另一个进程使用。

 stream =  new  FileStream （filename，FileMode.Open，FileAccess.Read，
 FileShare.Read）; 
  //  要读取的总字节数： 
  long  bytesToRead = stream.Length; 
 Response.ContentType =   application / msword; 
 Response.AddHeader（  Content-Disposition，  attachment; filename = + strFileName）; 
  //  从流中读取小部分的字节数。 
  while （bytesToRead >   0 ）
 {
  //  确保客户端仍然连接。 
  if （Response.IsClientConnected）
 {
  //  将数据读入缓冲区并写入 
  //  输出流。  
  byte  [] buffer =  new  字节 [ 10000 ]; 
  int  length = stream.Read（buffer， 0 ， 10000 ）; 
 Response.OutputStream.Write（buffer， 0 ，length）; 
 Response.Flush（）; 
  //  我们已经阅读了一些字节..需要阅读 
 < span class =code-comment> //  仅剩余。 
 bytesToRead = bytesToRead  -  length; 
} 
 其他 
 {
  //  < span class =code-comment>如果用户不再连接，退出循环..  
 bytesToRead = -1; 
} 
} 
} 
  catch （例外情况）
 {
 Response.Write （ex.Message）; 
  //  发生错误..  
} 
  finally  
 {
  if （stream！=  null ）
 {
 stream.Close（）; 
 stream.Dispose（）; 
} 
} 
} 
 
 
}

The process cannot access the file ''C:\inetpub\wwwroot\wss\VirtualDirectories\80\Upload\mydoc_2013-05-03.doc'' because it is being used by another process.

stream = new FileStream(filename, FileMode.Open, FileAccess.Read,
                                               FileShare.Read);
                       // Total bytes to read:
                       long bytesToRead = stream.Length;
                       Response.ContentType = "application/msword";
                       Response.AddHeader("Content-Disposition", "attachment; filename=" + strFileName);
                       // Read the bytes from the stream in small portions.
                       while (bytesToRead > 0)
                       {
                           // Make sure the client is still connected.
                           if (Response.IsClientConnected)
                           {
                               // Read the data into the buffer and write into the
                               // output stream.
                               byte[] buffer = new Byte[10000];
                               int length = stream.Read(buffer, 0, 10000);
                               Response.OutputStream.Write(buffer, 0, length);
                               Response.Flush();
                               // We have already read some bytes.. need to read
                               // only the remaining.
                               bytesToRead = bytesToRead - length;
                           }
                           else
                           {
                               // Get out of the loop, if user is not connected anymore..
                               bytesToRead = -1;
                           }
                       }
                   }
                   catch (Exception ex)
                   {
                       Response.Write(ex.Message);
                       // An error occurred..
                   }
                   finally
                   {
                       if (stream != null)
                       {
                           stream.Close();
                           stream.Dispose();
                       }
                   }
               }


           }

解决方案

Please see my past answer: The process cannot access the file ''C:\inetpub\wwwroot\wss\VirtualDirectories\80\Upload\KingSize_2013-04-29.pdf'' because it is being used by another process.[^].
