Can anyone tell me the difference between these two lines of code?

Code:
            Dim sBuff As Byte() = Encoding.ASCII.GetBytes(Msg)
            Dim sBuff() As Byte = Encoding.ASCII.GetBytes(Msg)
I'm sure there is some difference even though they perform exactely the same. Just one of those little nags that get me because I can't seem to find the answer in the MSDN Library.
