RemoteEndPoint vs. LocalEndPoint

作为C#网络的初学者，我编写了一个简单的Client-Server应用程序。我正在连接到我的本地IPAddress和服务器正在侦听的端口8080。

客户端：

        IPAddress remoteaddr = IPAddress.Parse("127.0.0.1");
        int port = 8880;
        TcpClient tcpclient = new TcpClient();
        tcpclient.Connect(remoteaddr, port);
        NetworkStream networkstream = tcpclient.GetStream();
        IPEndPoint RemAddr = (IPEndPoint)tcpclient.Client.RemoteEndPoint;
        IPEndPoint LocAddr = (IPEndPoint)tcpclient.Client.LocalEndPoint;
        if (RemAddr != null)
        {
            // Using the RemoteEndPoint property.
            Console.WriteLine("I am connected to " + RemAddr.Address + "on port number " + RemAddr.Port);
        }
        if (LocAddr != null)
        {
            // Using the LocalEndPoint property.
            Console.WriteLine("My local IpAddress is :" + LocAddr.Address + "I am connected on port number " + LocAddr.Port);
        }

输出为：

I am connected to 127.0.0.1 on port number 8880
My local IpAddress is :127.0.0.1 I am connected on port number 46715

那么RemoteEndPoint和LocalEndPoint之间有什么区别呢？LocalEndpointPort（在我的示例中为46715）有什么用途？它来自哪里？谢谢
