首先使用 C# 中的 Dns.GetHostName() 方法查找主机名 -

String hostName = string.Empty;
hostName = Dns.GetHostName();
Console.WriteLine("Hostname: "+hostName);

现在，使用 IPHostEntry.AddressList 属性来获取 IP 地址 -

IPHostEntry myIP = Dns.GetHostEntry(hostName);
IPAddress[] address = myIP.AddressList;

示例

尝试以下代码来显示 IP 地址 -

using System;
using System.Net;
class Program {
   static void Main() {
      String hostName = string.Empty;
      hostName = Dns.GetHostName();
      IPHostEntry myIP = Dns.GetHostEntry(hostName);
      IPAddress[] address = myIP.AddressList;
      for (int i = 0; i < address.Length; i++) {
         Console.WriteLine("IP Address {1} : ",address[i].ToString());
      }
      Console.ReadLine();
   }
}
