Reads a portion of data received via a specific channel into a byte array.
Use this method to read out a piece of data received from the server into a byte array. Specify the channel that you are interested in reading from (0 for stdout, 1 for stderr) via the Channel parameter, and control the maximum length of the data chunk with the MaxLen parameter.
Note that in synchronous mode this method may block in the absence of any inbound data until the next piece of data is received from the server. Use Poll to check if there is any data in the connection that is immediately available for reading.
In asynchronous mode a good time to call this method is upon receiving a read notification in DataReceived event handler. When working in asynchronous mode, this call returns immediately.
Please also note that stdout and stderr channels are fully independent, which implies that data arriving via each channel should be read out separately.
