C# 获得本机IP、端口等信息地址以及服务器IP信息

大概是这样子，代码也没多少，直接上代码了。。

引入命名空间：

using System.Net;  

 

完整代码：

namespace IPExample  
{  
    public partial class Form1 : Form  
    {  
        public Form1()  
        {  
            InitializeComponent();  
        }  
  
        /// <summary>  
        /// 获得本机IP信息  
        /// </summary>  
        /// <param name="sender"></param>  
        /// <param name="e"></param>
        private void btn_ShowHostIPInfo_Click(object sender, EventArgs e)  
        {  
            lst_HostIPInfo.Items.Clear();  
            string name = Dns.GetHostName();  
            lst_HostIPInfo.Items.Add("本机主机名："+name);  
            IPHostEntry me = Dns.GetHostEntry(name);  
            lst_HostIPInfo.Items.Add("本机所有IP地址：");  
            foreach (IPAddress ip in me.AddressList)  
            {  
                lst_HostIPInfo.Items.Add(ip);  
            }  
            IPAddress localIp = IPAddress.Parse("127.0.0.1");  
            IPEndPoint iep = new IPEndPoint(localIp, 80);  
            lst_HostIPInfo.Items.Add("IP端点：" + iep.ToString());  
            lst_HostIPInfo.Items.Add("IP端口：" + iep.Port);  
            lst_HostIPInfo.Items.Add("IP地址：" + iep.Address);  
            lst_HostIPInfo.Items.Add("IP地址族：" + iep.AddressFamily);  
            lst_HostIPInfo.Items.Add("可分配端口最大值：" + IPEndPoint.MaxPort);  
            lst_HostIPInfo.Items.Add("可分配端口最小值：" + IPEndPoint.MinPort);  
        }  
  
  
        /// <summary>  
        /// 获得服务器信息  
        /// </summary>  
        /// <param name="sender"></param>  
        /// <param name="e"></param>
        private void btn_ShowServerInfo_Click(object sender, EventArgs e)  
        {  
            lst_ServerIPInfo.Items.Clear();  
            IPHostEntry remoteHost = Dns.GetHostEntry(txt_ServerIPAddress.Text);  
            IPAddress[] remoteIp = remoteHost.AddressList;  
            IPEndPoint iep;  
            foreach (IPAddress ip in remoteIp)  
            {  
                iep = new IPEndPoint(ip, 80);  
                lst_ServerIPInfo.Items.Add(iep);  
            }  
        }  
  
  
    }  
}
