[RESOLVED] Padding error...

Hello, this is my code:

vb.net Code:

Public Overloads Shared Function RijndaelDecryptString(ByVal text As String, ByVal key As String) As String
        Dim _encKey As Byte() = CheckKey(key)
        Dim _textBytes As Byte() = Convert.FromBase64String(text)
        Return RijndaelDecryptString(_encKey, _textBytes)
    End Function
 
    Public Overloads Shared Function RijndaelDecryptString(ByVal data As Byte(), ByVal key As Byte())
        Try
            _rijndaelAlg.BlockSize = 256
            Dim _memStream As New MemoryStream(data)
            Dim _decryptedText(data.Length - 1) As Byte
            Dim cStream As New CryptoStream(_memStream, _
                                            _rijndaelAlg.CreateDecryptor(key, _IV), _
                                            CryptoStreamMode.Read)
            cStream.Read(_decryptedText, 0, _decryptedText.Length)
            cStream.Close()
            _memStream.Close()
            Return _encoding.GetString(_decryptedText)
        Catch ex As Exception
            Return ex.Message
        End Try
    End Function

Now, when I run that code it gives me the following error:

Padding is invalid and cannot be removed.

But, if I put everything into one function it works like a charm, why is that?

Thanks in advance!

P.S: I'm creating a class, that's why I'm using Overloads.

I got the answer, I had been passing the wrong variables. Thread solved!
