I have this method to encode a URL:

        ' Encode a string
        Public Function Encode(ByVal tcString As String) As String
            Return System.Web.HttpUtility.UrlEncode(tcString)
        End Function

However, this one replaces spaces with + and not %20. It has been a while since the last time I used this method. Or, am I using the wrong System.Web.HttpUtility method?
