How does the timeout apply on StreamSocket.readAsync()?

问题

I have created the streamSocket that received the stream of media. I want to read the stream on this socket and also want to apply readTimeout. So that I have applied it using CancellationTokenSource. As per my requirement, if I cant read within timeout limit, I dont want to close this socket. However, applying cancellation token causes the socket close in my program.

Is there any way to apply time out without closing the socket?

await socket.InputStream.ReadAsync(readBuffer, 8,     InputStreamOptions.None).AsTask(cts.Token);
