.NET 中的 UDP 套接字客户端
我在客户端应用程序中使用 UDP Sokckts。 以下是一些代码片段：
SendIP = new IPEndPoint(IPAddress.Parse(IP), port);
ReceiveIP = (EndPoint)(new IPEndPoint(IPAddress.Any, 0));
socket = new Socket(
AddressFamily.InterNetwork,
SocketType.Dgram,
ProtocolType.Udp);
socket.Bind(ReceiveIP);
接收 (while(true)):
byte[] data = new byte[BUFFERSIZE];
int receivedDataLength = socket.ReceiveFrom(data, ref ReceiveIP);
string s= Encoding.ASCII.GetString(data, 0, receivedDataLength);
我在接收时执行无限 while 操作，即使没有收到任何内容，同时还有其他事情要做。我想检查是否有实际上有可用数据，然后接收，否则不要等待。请注意，当前的接收方法会等待服务器发送消息。
I use UDP Sokckts in my client application.
Here are some code snippets:
SendIP = new IPEndPoint(IPAddress.Parse(IP), port);
ReceiveIP = (EndPoint)(new IPEndPoint(IPAddress.Any, 0));
socket = new Socket(
AddressFamily.InterNetwork,
SocketType.Dgram,
ProtocolType.Udp);
socket.Bind(ReceiveIP);
And to Receive (while(true)):
byte[] data = new byte[BUFFERSIZE];
int receivedDataLength = socket.ReceiveFrom(data, ref ReceiveIP);
string s= Encoding.ASCII.GetString(data, 0, receivedDataLength);
I am doing an infinite while on the receive, there are other things to be done in the while, even if nothing is received.. I want to check if there are actually available data then receive else do not wait. Note the current receive method waits until the server sends a message.

您可以在调用
ReceiveFrom()之前使用socket.Available()来确定是否有任何等待数据。不过，理想情况下，您应该考虑使用 BeginReceiveFrom() 及其异步朋友将输入处理外包给其他线程。You could use
socket.Available()to determine if there is any waiting data before callingReceiveFrom(). Ideally, though, you should consider farming out input handling to other threads usingBeginReceiveFrom()and its asynchronous friends.
