如何在UWP中从StreamSocketListener中获取数据？

StreamSocketListener listener = new StreamSocketListener();
await listener.BindServiceNameAsync(port.ToString());

listener.ConnectionReceived += Listener_ConnectionReceived;

private async void Listener_ConnectionReceived(StreamSocketListener sender, StreamSocketListenerConnectionReceivedEventArgs args)
{
    using (DataReader reader = new DataReader(args.Socket.InputStream))
    {
        try
        {
            // 读取数据
            await reader.LoadAsync(bufferSize);
            string data = reader.ReadString(reader.UnconsumedBufferLength);
            
            // 处理数据
            // ...
        }
        catch (Exception ex)
        {
            // 处理异常
            // ...
        }
    }
}
