突然间，这个exception开始发生在我的程序中。 任何想法，可能是什么原因？
运行在.NET 4.0上
at System.Net.UnsafeNclNativeMethods.OSSOCK.recv(IntPtr socketHandle, Byte* pinnedBuffer, Int32 len, SocketFlags socketFlags) at System.Net.Sockets.Socket.Receive(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags, SocketError& errorCode) at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Net.PooledStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Net.Connection.SyncRead(HttpWebRequest request, Boolean userRetrievedStream, Boolean probeRead) at System.Net.ConnectStream.ProcessWriteCallDone(ConnectionReturnResult returnResult) at System.Net.HttpWebRequest.GetResponse() at System.Net.WebClient.GetWebResponse(WebRequest request) at System.Net.WebClient.DownloadBits(WebRequest request, Stream writeStream, CompletionDelegate completionDelegate, A syncOperation asyncOp) at System.Net.WebClient.UploadValues(Uri address, String method, NameValueCollection data) 程序的内部深处有一个Thread.Abort（）调用。 这是原因。
