C# 传递给套接字侦听器的参数无效

我一直在不断地收到这个错误，我相信我把问题缩小到我是64位机器上的监听器。有没有办法让它在64位系统上运行

18      Socket sListener;
...
34          permission = new SocketPermission(NetworkAccess.Accept, TransportType.Tcp, "", SocketPermission.AllPorts);

36          //Listening Socket object
37          sListener = null;

39          //Ensure the code has permission to access the Socket
40          permission.Demand();

42          IPHostEntry ipHost = Dns.GetHostEntry("");
43          IPAddress ipAddress = ipHost.AddressList[2];
44          ipEndPoint = new IPEndPoint(ipAddress, 4510);

46          sListener = new Socket(ipAddress.AddressFamily, SocketType.Stream, ProtocolType.Tcp);
...
71      sListener.Listen(10);
72
73      //Begins an asynchronous operation to accept an attempt
74      AsyncCallback aCallback = new AsyncCallback(AcceptCallback);
75      sListener.BeginAccept(aCallback, sListener);

我试图按照这个问题中的代码进行操作，但它给了我一个错误：

运算符“==”不能应用于“System.Net.Sockets.AddressFamily”和“string”类型的操作数

是否检查了中讨论的

MaxConnections

属性

该文档还介绍了如何检查

ErrorCode

，以了解更多详细信息。也许你应该探索一下这个选项。

我认为你错过了，在一个端口上可以安装一个套接字之前

根据MSDN：

如果需要使用特定的本地端点，请使用Bind方法。你 必须先调用Bind，然后才能调用Listen方法。你不需要 在使用Connect方法之前调用Bind，除非需要使用 特定的本地端点。您可以在这两种情况下使用Bind方法 无连接和面向连接的协议

在调用Bind之前，必须首先从 您打算在其中传递数据。如果你不在乎哪个地方 如果已分配地址，则可以使用IPAddress创建IPEndPoint。任何 作为地址参数，基础服务提供商将 分配最合适的网络地址。这可能有助于简化 如果您有多个网络接口，请选择您的应用程序。如果你这样做 不管使用哪个本地端口，都可以使用 端口号为0。在这种情况下，服务提供商将分配 介于1024和5000之间的可用端口号

注意：侦听端口始终使用大于4000的值

也许下面的示例也会对您有所帮助

Socket clientSocket;
System.Net.IPEndPoint clientEndPoint;
System.Net.Sockets.NetworkStream networkStream;
IAsyncResult beginAcceptAsyncResult;
System.Threading.WaitHandle []waitHandleArray;
int waitHandleSignalled;

System.Net.IPEndPoint listenEndpoint = new System.Net.IPEndPoint("127.0.0.1", 45000); //make sure port is free (check with cmd: netstat -an)
System.Net.Sockets.TcpListener listener = new System.Net.Sockets.TcpListener(listenEndpoint);

waitHandleArray = new System.Threading.WaitHandle[1];

listener.Start();

do
{
    try
    beginAcceptAsyncResult = listener.BeginAcceptSocket(null, null);
    waitHandleArray[0] = beginAcceptAsyncResult.AsyncWaitHandle;
    waitHandleSignalled = System.Threading.WaitHandle.WaitAny(waitHandleArray);

    if (waitHandleSignalled != 0)
    {
        clientSocket = _TCPListener.EndAcceptSocket(BeginAcceptAsyncResult);

        clientEndPoint = clientSocket.RemoteEndPoint as System.Net.IPEndPoint;

        networkStream = new System.Net.Sockets.NetworkStream(clientSocket, true);

        //do more with NetworkStream...
    }
}
//...
//...

在代码中，我找不到与

==

相关的任何内容。对于从相关问题中得到的代码中的错误，AddressFamily是一个枚举。尝试

==AddressFamily.InterNetwork

而不是

==“InterNetwork”

Socket clientSocket;
System.Net.IPEndPoint clientEndPoint;
System.Net.Sockets.NetworkStream networkStream;
IAsyncResult beginAcceptAsyncResult;
System.Threading.WaitHandle []waitHandleArray;
int waitHandleSignalled;

System.Net.IPEndPoint listenEndpoint = new System.Net.IPEndPoint("127.0.0.1", 45000); //make sure port is free (check with cmd: netstat -an)
System.Net.Sockets.TcpListener listener = new System.Net.Sockets.TcpListener(listenEndpoint);

waitHandleArray = new System.Threading.WaitHandle[1];

listener.Start();

do
{
    try
    beginAcceptAsyncResult = listener.BeginAcceptSocket(null, null);
    waitHandleArray[0] = beginAcceptAsyncResult.AsyncWaitHandle;
    waitHandleSignalled = System.Threading.WaitHandle.WaitAny(waitHandleArray);

    if (waitHandleSignalled != 0)
    {
        clientSocket = _TCPListener.EndAcceptSocket(BeginAcceptAsyncResult);

        clientEndPoint = clientSocket.RemoteEndPoint as System.Net.IPEndPoint;
