How to detect socket disconnection in .NET?

After spending few days, finally able to figure socket disconnect detection in .NET 🙂

 

Public Shared Function IsConnected(ByVal socket As Socket) As Boolean
        Try
            Return Not (socket.Poll(1, SelectMode.SelectRead) AndAlso socket.Available = 0)
        Catch generatedExceptionName As SocketException
            Return False
        End Try
End Function

In Timer_tick event, keep checking for connection status.  If return value is ‘false’, we can say that socket is disconnected now 🙂
