Question

请帮帮我，我被困了

未处理的类型异常＆＃39; System.Runtime.Serialization.SerializationException＆＃39;发生在 mscorlib.dll中

其他信息：解析完成之前遇到的流结束。

执行方法

时会出现Above错误

void ReceiveCallback(IAsyncResult AR)
{
    using (ms = new MemoryStream())
    {
        Socket localsock = (Socket)AR.AsyncState;
        int RecLen = localsock.EndReceive(AR);
        Array.Resize(ref buffer, RecLen);
        bnrFormatter = new BinaryFormatter();                
        ms.Write(buffer, 0, buffer.Length);
        ms.Position = 0;                
        AddListItem("MS length:" + ms.Length + "\nMS position: " + ms.Position);            
        TrackerData data = (TrackerData)bnrFormatter.Deserialize(ms);

        if (pushToDB(data) == 1)
        {
            AddListItem("New packet data received from client of IP " + ((IPEndPoint)localsock.LocalEndPoint).Address.ToString() + " and Port " + ((IPEndPoint)localsock.LocalEndPoint).Port + " .");
        }
        byte[] resBuffer = Encoding.Default.GetBytes("New packet data sent to the server!!");
        localsock.BeginSend(resBuffer, 0, resBuffer.Length, SocketFlags.None, new AsyncCallback(EndCallback), localsock);
        localsock.BeginReceive(buffer, 0, buffer.Length, SocketFlags.None, new AsyncCallback(ReceiveCallback), localsock);
    }
}

错误在行

中出现

TrackerData data = (TrackerData)bnrFormatter.Deserialize(ms);

试试这个解决方案。将位置设置为内存流的0，不要使用对象，而是使用对象类型。

  ms.Position = 0;
  BinaryFormatter bnrFormatter = new BinaryFormatter();
  TrackerData data = (TrackerDataObjectType)bnrFormatter .Deserialize(ms);

类型为＆＃39; System.Runtime.Serialization.SerializationException＆＃39;的未处理异常发生在mscorlib.dll
