如何在 C# 中获取机器的 IP 地址？
采纳答案by Richard Szalay
IPAddress[] localIPs = Dns.GetHostAddresses(Dns.GetHostName());
Your machine doesn't have a single IP address, and some of the returned addresses can be IPv6.
你的机器没有一个单一的 IP 地址，一些返回的地址可以是 IPv6。

Alternatively, as MSaltersmentioned, 127.0.0.1/ ::1is the loopback addressand will always refer to the local machine. For obvious reasons, however, it cannot be used to connect to the local machine from a remote machine.
或者，正如MSalters 所提到的，127.0.0.1/::1是环回地址，并且总是指本地机器。然而，由于显而易见的原因，它不能用于从远程机器连接到本地机器。

IPHostEntry ip = DNS.GetHostByName (strHostName);
IPAddress [] IPaddr = ip.AddressList;
for (int i = 0; i < IPaddr.Length; i++)
{
Console.WriteLine ("IP Address {0}: {1} ", i, IPaddr[i].ToString ());
}

My desired answer was
我想要的答案是
string ipAddress = "";
if (Dns.GetHostAddresses(Dns.GetHostName()).Length > 0)
{
ipAddress = Dns.GetHostAddresses(Dns.GetHostName())[0].ToString();
}

string hostName = Dns.GetHostName(); // Retrive the Name of HOST
// Get the IP
string myIP = Dns.GetHostByName(hostName).AddressList[0].ToString();
//use Following Namespace- using System.Net;
//使用以下命名空间-使用System.Net;
