TryReceiveMultipartMessage() public static method

Attempt to receive all frames of the next message from socket. If no message is available within timeout, return false.

public static TryReceiveMultipartMessage ( [ socket, System.TimeSpan timeout, [ message, int expectedFrameCount = 4 ) : bool
socket	[	The socket to receive from.
timeout	System.TimeSpan	The maximum period of time to wait for a message to become available.
message	[	The received message. Untouched if no message was available.
expectedFrameCount	int	Specifies the initial capacity of the used /// to buffer results. If the number of frames is known, set it here. If more frames arrive than expected, /// an extra allocation will occur, but the result will still be correct.
return	bool
