我是靠谱客的博主体贴乌冬面，最近开发中收集的这篇文章主要介绍c# 使用TcpClient TcpListener类服务器和客户端实现双向连接 web service web socket，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

在这里插入图片描述

通过web service获取服务器ip地址端口先写5000

using Newtonsoft.Json;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Web;
using System.Web.Services;

namespace WebApplication1
{
    /// <summary>
    /// WebService1 的摘要说明
    /// </summary>
    [WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    // 若要允许使用 ASP.NET AJAX 从脚本中调用此 Web 服务，请取消注释以下行。 
    // [System.Web.Script.Services.ScriptService]
    public class WebService1 : System.Web.Services.WebService
    {
         [WebMethod(Description = "获取服务器ip地址 端口")]
        public string GetIP()
        {
            string AddressIP = string.Empty;
            //Dns.GetHostEntry(Dns.GetHostName()).AddressList
            foreach (IPAddress _IPAddress in Dns.GetHostAddresses(Dns.GetHostName()))
            {
                if (_IPAddress.AddressFamily.ToString() == "InterNetwork")
                {
                    AddressIP = _IPAddress.ToString();
                }
            }
            return JsonConvert.SerializeObject(new { state = true, IP = AddressIP,Port="5000" });
        }
    }
}
