C# System.Net.Sockets.SocketException（0x80004005）：主机中的软件中止了已建立的连接

我制作了一个windows服务远程服务器程序，它能够与windows CE deviceas远程客户端进行通信，监听广播请求，将请求保存到文件中，检查并发回正在跟踪的请求文件内容。我已经在c异步传输模式下实现了它。它工作正常，但就在2天前，我遇到了此套接字异常：

System.Net.Sockets.SocketException 0x80004005:主机中的软件在System.Net.Sockets.Socket.BeginReceiveByte[]缓冲区、Int32偏移量、Int32大小、SocketFlags SocketFlags、AsyncCallback回调、对象状态中止了已建立的连接

这是我的代码，它指向异常

     public void AcceptCallback(IAsyncResult result)
     { 

          ConnectionInfo connection = new ConnectionInfo();
          try
          {
              long connection_number;

              //finish accept
              Socket s;
              s = (Socket)result.AsyncState;
              connection.socket = s.EndAccept(result);

              connection.socket.Blocking = false;

              connection.Buffer = new byte[10000]; //1kb buffer minimum


     orionIP = ((IPEndPoint)connection.socket.RemoteEndPoint).Address.ToString();
               lock (connections) connections.Add(connection);
             IPHostEntry hostName = Dns.GetHostEntry(orionIP);
               machineName = hostName.HostName;
               lock (connections) connections.Add(connection);
                //count client connected
              connection_number = Interlocked.Increment(ref connection_count);

              //start receive -> error here 
   connection.socket.BeginReceive(connection.Buffer, 0, connection.Buffer.Length,
                  SocketFlags.None, new AsyncCallback(ReceiveCallBack), connection);

            //start new accept 
             serverSocket.BeginAccept(new AsyncCallback(AcceptCallback), result.AsyncState);

          }//end try 
          catch (SocketException ex)
          { //later log files for error events  - > ex.SocketErrorCode
              string path = "eventlogs.txt";
              //create error log files to write error here 
              File.WriteAllText(path, ex.ToString());
              CloseConnection(connection);
          }
          catch (Exception exp)
          {
              string path = "eventlogs.txt";
              //create error log files to write error here 
              File.WriteAllText(path, exp.ToString());
              CloseConnection(connection);
              // log error file later ("Socket Exception:" + exp.ToString());
          }
     }

发生异常时，我没有对其进行重大修改。我按照所有说明操作，其他人也遇到同样的问题，例如关闭防火墙、maxusePort、检查网络连接和设备（如果配置正确）、缓冲区大小。我还检查了可能要处理的竞争条件和WSAECONNABORTED问题

与这个问题有关的人能给我一些额外的解决方案吗？任何额外的知识都会有很大的帮助

如果当前接受的连接出现网络错误，则不接受新连接。将BeginAccept移动到单独的try/catch

public void AcceptCallback(IAsyncResult result)
{ 

    ConnectionInfo connection = new ConnectionInfo();
    try
    {
        long connection_number;

        Socket s;
        s = (Socket)result.AsyncState;
        connection.socket = s.EndAccept(result);
        connection.socket.Blocking = false;
        connection.Buffer = new byte[10000]; //1kb buffer minimum


        orionIP = ((IPEndPoint)connection.socket.RemoteEndPoint).Address.ToString();
        lock (connections) connections.Add(connection);
        IPHostEntry hostName = Dns.GetHostEntry(orionIP);
        machineName = hostName.HostName;
        lock (connections) connections.Add(connection);
        connection_number = Interlocked.Increment(ref connection_count);

        connection.socket.BeginReceive(connection.Buffer, 0, connection.Buffer.Length,
        SocketFlags.None, new AsyncCallback(ReceiveCallBack), connection);
    }
    catch (SocketException ex)
    {
        string path = "eventlogs.txt";
        File.WriteAllText(path, ex.ToString());
        CloseConnection(connection);
    }
    catch (Exception exp)
    {
        string path = "eventlogs.txt";
        File.WriteAllText(path, exp.ToString());
        CloseConnection(connection);
    }

    try
    {
        serverSocket.BeginAccept(new AsyncCallback(AcceptCallback), result.AsyncState);
    }
    catch (Exception exception)
    {
        //failed to accept. shut down service.
    }
}

我已经做了您建议的更改，但套接字异常仍然存在。当我将设备与主机分离时，碰巧收到了这个异常，实际上我正在使用超级终端来测试发送请求功能。似乎连接已经建立，客户端可以连接，但当将一些数据传输回服务器时，它会关闭连接并丢失其他数据包。然后，我认为问题不在AcceptCallback中，而是在receive callback中receive callback中可能出了什么问题。这是我的密码：对不起，我只是有一些互联网连接问题。这是我的接收回调代码。尝试{ConnectionInfo connection=ConnectionInfo结果.AsyncState；int bytesRead=connection.socket.EndReceiveresult；如果bytesRead>0{lock serverlock{connection.sb.AppendEncoding.UTF8.GetStringconnection.Buffer，0，bytesRead；}锁定连接{foreach ConnectionInfo conn in connections{if connection！=conn{conn.socket.Sendconnection.Buffer，bytesRead，SocketFlags.None；}}connection.socket.BeginReceiveconnection.Buffer，0，connection.Buffer.Length，SocketFlags.None，//新建AsyncCallbackReceiveCallBack，连接；connection.socket.BeginReceiveconnection.Buffer，0，新建AsyncCallbackReceiveCallBack，连接；}

public void AcceptCallback(IAsyncResult result)
{ 

    ConnectionInfo connection = new ConnectionInfo();
    try
    {
        long connection_number;

        Socket s;
        s = (Socket)result.AsyncState;
        connection.socket = s.EndAccept(result);
        connection.socket.Blocking = false;
        connection.Buffer = new byte[10000]; //1kb buffer minimum


        orionIP = ((IPEndPoint)connection.socket.RemoteEndPoint).Address.ToString();
        lock (connections) connections.Add(connection);
        IPHostEntry hostName = Dns.GetHostEntry(orionIP);
        machineName = hostName.HostName;
        lock (connections) connections.Add(connection);
        connection_number = Interlocked.Increment(ref connection_count);

        connection.socket.BeginReceive(connection.Buffer, 0, connection.Buffer.Length,
        SocketFlags.None, new AsyncCallback(ReceiveCallBack), connection);
    }
    catch (SocketException ex)
    {
        string path = "eventlogs.txt";
        File.WriteAllText(path, ex.ToString());
        CloseConnection(connection);
    }
    catch (Exception exp)
    {
        string path = "eventlogs.txt";
        File.WriteAllText(path, exp.ToString());
        CloseConnection(connection);
    }

    try
    {
        serverSocket.BeginAccept(new AsyncCallback(AcceptCallback), result.AsyncState);
    }
    catch (Exception exception)
    {
        //failed to accept. shut down service.
    }
