Comparing strings always fails (string converted from Byte()) - vb.net

Question

My application is receiving commands via TCP, if I attempt to compare the command the comparison always fails.
The message is converted to a byte() and back but should compare ok in the below example? Or am I missing something?
Imports MyApp.Client
Public Class Form1
Public Delegate Sub MessageReceivedHandler(ByVal message As String)
Private Sub Message_Received(ByVal message As String)
'update the display using invoke
Invoke(New MessageReceivedHandler(AddressOf PrintToScreen), New Object() {message})
End Sub
Private Sub PrintToScreen(ByVal msg As String)
Select Case msg
Case "#all"
'Do Something
Case Else
'Do Something Else
End Select
End Sub
End Class
'Client class
Public Class Client
Private _tcpClient As TcpClient
Public Event MessageReceived As MessageReceivedHandler
Public Sub Connect(ByVal address As IPAddress, ByVal port As Integer)
_tcpClient = New TcpClient()
Dim serverEndPoint As New IPEndPoint(address, port)
_tcpClient.Connect(serverEndPoint)
ThreadPool.QueueUserWorkItem(New WaitCallback(AddressOf Read))
End Sub
Public Sub Send(ByVal buffer As Byte())
_tcpClient.GetStream().Write(buffer, 0, buffer.Length)
_tcpClient.GetStream().Flush()
End Sub
Private Sub Read()
Dim encoder As New ASCIIEncoding()
Dim buffer As Byte() = New Byte(4095) {}
Dim bytesRead As Integer
While True
Try
bytesRead = _tcpClient.GetStream().Read(buffer, 0, 4096)
RaiseEvent MessageReceived(encoder.GetString(buffer, 0, bytesRead).ToString)
Catch ex As IO.IOException
Application.Exit()
End Try
End While
End Sub
Public Sub Dispose()
_tcpClient.Close()
End Sub
End Class
The variable is a string containing the same text as the case, yet it fails the comparison:

Found the problem, the sending application was adding a vbNullChar to the end of the string before converting to a byte() and sending over. (Could not see a method to remove it from the string converted on the receiving end)
