UDP套接字 - 客户端数据包接收异常

我已经建立了这个UDP客户端:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net;
using System.Net.Sockets;
using System.Threading;

namespace UDP_Client
{
    class Program
    {
        static void Main(string[] args)
        {
            Program go = new Program();
            go.Client();
        }
        void Client()
        {
            byte[] msg = new byte[1000];
            Socket sck = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
            IPEndPoint x = new IPEndPoint(IPAddress.Parse("127.0.0.1"), 12345);
            IPEndPoint sender = new IPEndPoint(IPAddress.Any, 0);
            int PacketSize = sck.Receive(msg); // <- The exception is thrown here, when the client tries to receive a packet
            Console.WriteLine(Encoding.ASCII.GetString(msg));
            Console.ReadKey();
        }
    }
}

所以,问题是,每当我尝试使用客户端接收消息时,它都会抛出SocketException(提供了无效的参数)。

这是什么问题?在收到之前我忘了做某事吗?

我不会在这里使用Bind,因为它是客户端而不是服务器。
