通过WCF文件Stream
原标题:Passing FileStream in WCF

在我从客户到服务处查阅档案以及开始向客户下载服务之后,我如何从客户方面确定到现在为止有多少 by(同时使用档案物体)?

我的目标是,将客户的上载速度仅用于这一档案,而我所能认为的唯一办法就是这样做。

最佳回答

扩展档案馆或为其制作一个包裹。 将“方法”改为“方法”,对“字体”改为“反面”。

延长期限(不适当执行,但应足以解释)

   public class CountingStream : System.IO.FileStream {

      // provide appropriate constructors

      // may want to override BeginRead too

      // not thread safe

      private long _Counter = 0;

      public override int ReadByte() {
         _Counter++;
         return base.ReadByte();            
      }

      public override int Read(byte[] array, int offset, int count) {
         // check if not going over the end of the stream
         _Counter += count;
         return base.Read(array, offset, count);             
      }

      public long BytesReadSoFar {
         get {
            return _Counter;
         }
      }
   }
