Answer 1

// Read the bytes from the web socket and accumulate all into a list.
var buffer = new ArraySegment(new byte[1024]);
WebSocketReceiveResult result = null;
var allBytes = new List();

do

    result = await webSocket.ReceiveAsync(buffer, CancellationToken.None);
    for (int i = 0; i < result.Count; i++)
    {
        allBytes.Add(buffer.Array[i]);
    }
}
while (!result.EndOfMessage);

// Optional step to convert to a string (UTF-8 encoding).
var text = Encoding.UTF8.GetString(allBytes.ToArray(), 0, allBytes.Count);
