尝试同时侦听多个端口时出现SocketException C#

本文关键字：SocketException | 更新日期: 2023-09-27 18:26:01

我正在编写一个HTTP服务器，我想同时监听两个端口
我创建了两个套接字和两个endPoint，并将它们传递给线程
当代码处于socket.Bind(endPoint);时，我得到以下异常：

System.Net.Sockets.SocketException: Only one usage of each socket address (protocol/network address/port) is normally permitted

代码：

public class HTTPServer
{
    private readonly IPEndPoint m_LocalEndPoint=new IPEndPoint(IPAddress.Any, 8082);;
    private readonly IPEndPoint m_SecuredLocalEndPoint=new IPEndPoint(IPAddress.Any, 8083);
    private readonly Socket m_SocketListener=new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);;
    private readonly Socket m_SecureSocketListener=new Socket(AddressFamily.InterNetwork, SocketType.Stream,ProtocolType.Tcp);; 
    public void Start()
        {
            Thread t = ThreadFactory.Create(() => AsyncStart(m_LocalEndPoint,m_SocketListener));
            t.Name = string.Format("HTTPServer({0})", this);
            t.Start();
            Thread sucureThread = ThreadFactory.Create(() => AsyncStart(m_SecuredLocalEndPoint,m_SecureSocketListener));
            sucureThread.Name = string.Format("HTTPSServer({0})", m_SecuredLocalEndPoint);
            sucureThread.Start();
        }

    private void AsyncStart(IPEndPoint endPoint, Socket socket)
        {
            try
            {
                socket.Bind(endPoint);
                socket.Listen(MAX_NUMBER_OF_PENDING_CONNECTIONS);
                Socket clientSocket = socket.Accept();
            }
            catch (Exception ex)
            {
            }          
        }
}

我不知道它是否与这个问题有关，但我想监听两个端口的原因是我希望能够在同一台服务器中处理HTTP和HTTPS请求
因此，如果客户端向端口8082发送数据包，我将按照HTTP请求，如果他发送到8083，我将作为HTTPS请求处理
我缺少什么，或者如何解决此问题（避开SocketException）并仍然侦听两个端口？

尝试同时侦听多个端口时出现SocketException C#

如果套接字在特定端口上持续失败，则可能有另一个进程在侦听该端口。

在本地系统上运行端口扫描以确认端口空闲。
