I have this block of code in a .asp file that I am struggling to convert to c#... can anyone help me?
Function EncodeCPT(ByVal sPinCode, ByVal iOfferCode, ByVal sShortKey, ByVal sLongKey)
Dim vob(2), encodeModulo(256), decodeX, ocode
decodeX = " abcdefghijklmnopqrstuvwxyz0123456789!$%()*+,-.@;<=>?[]^_{|}~"
if len(iOfferCode) = 5 then
ocode = iOfferCode Mod 10000
else
ocode = iOfferCode
end if
vob(1) = ocode Mod 100
vob(0) = Int((ocode-vob(1)) / 100)
For i = 1 To 256
encodeModulo(i) = 0
Next
For i = 0 To 60
encodeModulo(asc(mid(decodeX, i + 1, 1))) = i
Next
'append offer code to key
sPinCode = lcase(sPinCode) & iOfferCode
If Len(sPinCode) < 20 Then
sPinCode = Left(sPinCode & " couponsincproduction", 20)
End If
'encode
Dim i, q, j, k, sCPT, s1, s2, s3
i = 0
q = 0
j = Len(sPinCode)
k = Len(sShortKey)
sCPT = ""
For i = 1 To j
s1 = encodeModulo(asc( mid(sPinCode, i, 1)) )
s2 = 2 * encodeModulo( asc( mid(sShortKey, 1 + ((i - 1) Mod k), 1) ) )
s3 = vob(i Mod 2)
q = (q + s1 + s2 + s3) Mod 61
sCPT = sCPT & mid(sLongKey, q + 1, 1)
Next
EncodeCPT = sCPT
End Function
