System.Net.Sockets - define a timeout? (C#)
提问by Mike
Is it possible to set a timeout when performing a port lookup as demonstrated in the code below?:
执行端口查找时是否可以设置超时，如下面的代码所示？：
try
{
System.Net.Sockets.Socket sock = new System.Net.Sockets.Socket(System.Net.Sockets.AddressFamily.InterNetwork, System.Net.Sockets.SocketType.Stream, System.Net.Sockets.ProtocolType.Tcp);
sock.Connect(ipa, portno1);
if (sock.Connected == true) // Port is in use and connection is successful
{
displayGreen1();
}
sock.Close();
}

Looks like this may be what you're looking for: http://www.codeproject.com/KB/IP/TimeOutSocket.aspx.

It seems that he's using
好像他在用
ManualResetEvent.WaitOne()
to block the main thread for the duration of the time-out. If
在超时期间阻塞主线程。如果
IsConnectionSuccessful
is false (i.e., the connection was not made in time or the callBack failed) when time runs out, an exception will be thrown.
为false（即连接未及时或callBack失败），超时则抛出异常。

Use code taken from here
使用从这里获取的代码
Socket socket = new Socket(
AddressFamily.InterNetwork,
SocketType.Stream,
ProtocolType.Tcp);
// Connect using a timeout (5 seconds)
IAsyncResult result = socket.BeginConnect(sIP, iPort, null, null);
bool success = result.AsyncWaitHandle.WaitOne(5000, true);
if (!_socket.Connected)
{
// NOTE, MUST CLOSE THE SOCKET
socket.Close();
throw new ApplicationException("Failed to connect server.");
}

FYI...
供参考...
Socket tcpSocket;
// Set the receive buffer size to 8k
tcpSocket.ReceiveBufferSize = 8192;
// Set the timeout for synchronous receive methods to
// 1 second (1000 milliseconds.)
tcpSocket.ReceiveTimeout = 1000;
// Set the send buffer size to 8k.
tcpSocket.SendBufferSize = 8192;
// Set the timeout for synchronous send methods
// to 1 second (1000 milliseconds.)
tcpSocket.SendTimeout = 1000;
