在C#中使用套接字通过局域网进行通信需要使用什么IP？

using System;
using System.Net;
using System.Net.Sockets;

class Program
{
    static void Main()
    {
        // 获取本地设备的IP地址
        string localIP = GetLocalIPAddress();

        // 创建套接字
        Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

        // 绑定本地IP和端口
        socket.Bind(new IPEndPoint(IPAddress.Parse(localIP), 1234));

        // 连接远程设备
        string remoteIP = "192.168.0.100"; // 假设远程设备的IP地址是192.168.0.100
        socket.Connect(new IPEndPoint(IPAddress.Parse(remoteIP), 1234));

        // 发送和接收数据...
    }

    static string GetLocalIPAddress()
    {
        // 获取本地设备的IP地址
        string localIP = "";
        foreach (var networkInterface in System.Net.NetworkInformation.NetworkInterface.GetAllNetworkInterfaces())
        {
            if (networkInterface.OperationalStatus == System.Net.NetworkInformation.OperationalStatus.Up)
            {
                foreach (var address in networkInterface.GetIPProperties().UnicastAddresses)
                {
                    if (address.Address.AddressFamily == AddressFamily.InterNetwork)
                    {
                        localIP = address.Address.ToString();
                        break;
                    }
                }
            }
        }
        return localIP;
    }
}
