guid to base64, for URL

Question

Question: is there a better way to do that?

VB.Net

Function GuidToBase64(ByVal guid As Guid) As String
    Return Convert.ToBase64String(guid.ToByteA         


        

Answer 1

I understand that the reason you are clipping == in the end is that because you can be certain that for GUID (of 16 bytes), encoded string will always end with ==. So 2 characters can be saved in every conversion.

Beside the point @Skurmedal already mentioned (should throw an exception in case of invalid string as input), I think the code you posted is just good enough.
