System.Net.Sockets.SocketException:远程主机强迫关闭了一个现有的连接（寻找错误解决答案）

System.Net.Sockets.SocketException:远程主机强迫关闭了一个现有的连接
在System.Net.Sockets.Socket.Receive(Byte[] buffer,Int32 offset,Int32 size,SocketFlags socketFlags);
在System.Net.Sockets.Socket.Receive(Byte[] buffer,Int32 size,SocketFlags socketFlags);
在WebProxy.Proxy.Run()位置：行64

行64为： Int32 rBytes = IPsocket.Receive(RecvBytes, RecvBytes.Length, 0);

一下是代码，有谁知道是什么原因不？
