问题描述

如何通过编程方式 确定是否可以使用C#访问具有给定IP地址和端口的服务器(TCP)?

How can I programmatically determine if I have access to a server (TCP) with a given IP address and port using C#?

推荐答案

假设您是通过TCP套接字进行访问的:

Assuming you mean through a TCP socket:

IPAddress IP;
if(IPAddress.TryParse("127.0.0.1",out IP)){
    Socket s = new Socket(AddressFamily.InterNetwork,
    SocketType.Stream,
    ProtocolType.Tcp);

    try{   
        s.Connect(IPs[0], port);
    }
    catch(Exception ex){
        // something went wrong
    }
}
