VbScript Function to encode into base64 compatible with .NET function System.Convert.FromBase64Strin

[abarberis]

I am using the following code to convert a byte array in vbscript which
is passed to a web service:

Function ByteArray2Text(varByteArray)
'Convert byte array into a string with VBScript
'60kb = 2 seconds, 100kb = 5 seconds, 200kb = 25 seconds
Dim strBuffer, lngCounter
strData = ""
strBuffer = ""
For lngCounter = 0 to UBound(varByteArray)
strBuffer = strBuffer & Chr(255 And Ascb(Midb(varByteArray,lngCounter
+ 1, 1)))
'Keep strBuffer at 1k bytes maximum
If lngCounter Mod 1000 = 0 Then
strData = strData & strBuffer
strBuffer = ""
End If
Next
ByteArray2Text = strData & strBuffer
End Function

I need to decode it with .NET. It seems that they are different because
I am getting invalid data when I decode using
System.Convert.FromBase64String.

Any ideas? I'm stuck!

Thanks

Alex

Sorry wrong function I meant this one:

Function Base64Encode(inData)
'rfc1521
'2001 Antonin Foller, Motobit Software, http://Motobit.cz
Const Base64 =
"ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/"
Dim cOut, sOut, I

'For each group of 3 bytes
For I = 1 To Len(inData) Step 3
Dim nGroup, pOut, sGroup

'Create one long from this 3 bytes.
nGroup = &H10000 * Asc(Mid(inData, I, 1)) + _
&H100 * MyASC(Mid(inData, I + 1, 1)) + MyASC(Mid(inData, I + 2,
1))

'Oct splits the long To 8 groups with 3 bits
nGroup = Oct(nGroup)

'Add leading zeros
nGroup = String(8 - Len(nGroup), "0") & nGroup

'Convert To base64
pOut = Mid(Base64, CLng("&o" & Mid(nGroup, 1, 2)) + 1, 1) + _
Mid(Base64, CLng("&o" & Mid(nGroup, 3, 2)) + 1, 1) + _
Mid(Base64, CLng("&o" & Mid(nGroup, 5, 2)) + 1, 1) + _
Mid(Base64, CLng("&o" & Mid(nGroup, 7, 2)) + 1, 1)

'Add the part To OutPut string
sOut = sOut + pOut

'Add a new line For Each 76 chars In dest (76*3/4 = 57)
'If (I + 2) Mod 57 = 0 Then sOut = sOut + vbCrLf
Next
Select Case Len(inData) Mod 3
Case 1: '8 bit final
sOut = Left(sOut, Len(sOut) - 2) + "=="
Case 2: '16 bit final
sOut = Left(sOut, Len(sOut) - 1) + "="
End Select
Base64Encode = sOut
End Function

Function MyASC(OneChar)
If OneChar = "" Then MyASC = 0 Else MyASC = Asc(OneChar)
End Function

Can you specify a charcter set in .NET?
