C#: Implementing NetworkStream.Peek?

Currently, there isn't a NetworkStream.Peek method in C#. What is the best way of implementing such a method which functions just like NetworkStream.ReadByte except that the returned byte is not actually removed from the Stream?

So, it would seem that a blocking Read() can return before it is done receiving all of the data being sent to it. In turn we wrap the Read() with a loop that is controlled by the DataAvailable value from the stream in question. The problem is that…

Why would BufferedStream.Write throw "This stream does not support seek operations"?

This one puzzles me. I get an error about seek when I'm not even calling it? I have code that looks something like this: // send 42 uint value = 42; byte[] msg = BitConverter.GetBytes(value); stream.Write(msg, 0, sizeof(uint)); and I get this…
