试试这个代码：
//Client uses as receive udp client
UdpClient Client = new UdpClient(Port);
try
{
Client.BeginReceive(new AsyncCallback(recv), null);
}
catch(Exception e)
{
MessageBox.Show(e.ToString());
}
//CallBack
private void recv(IAsyncResult res)
{
IPEndPoint RemoteIpEndPoint = new IPEndPoint(IPAddress.Any, 8000);
byte[] received = Client.EndReceive(res, ref RemoteIpEndPoint);
//Process codes
MessageBox.Show(Encoding.UTF8.GetString(received));
Client.BeginReceive(new AsyncCallback(recv), null);
}

对于使用 TAP 而不是 Begin/End 方法的较新方法，您可以在 .Net 4.5 中使用以下内容
非常简单！
异步方法
private static void UDPListener()
{
Task.Run(async () =>
{
using (var udpClient = new UdpClient(11000))
{
string loggingEvent = "";
while (true)
{
//IPEndPoint object will allow us to read datagrams sent from any source.
var receivedResults = await udpClient.ReceiveAsync();
loggingEvent += Encoding.ASCII.GetString(receivedResults.Buffer);
}
}
});
}
同步法
与asynchronous上面的方法一样，这也可以在synchronous方法中以非常相似的方式实现：
private static void UDPListener()
{
Task.Run(() =>
{
using (var udpClient = new UdpClient(11000))
{
string loggingEvent = "";
while (true)
{
//IPEndPoint object will allow us to read datagrams sent from any source.
var remoteEndPoint = new IPEndPoint(IPAddress.Any, 0);
var receivedResults = udpClient.Receive(ref remoteEndPoint);
loggingEvent += Encoding.ASCII.GetString(receivedResults);
}
}
});
}
