Simple RSA Explanation

Anyone know how to correctly convert the base64 encoded P and Q values back to a proper integer?

I am trying to use the systems.numerics biginteger format and the output isn't looking correct. My Byte Arrays are coming back correctly from my RSAGetP function, as if I convert the array back to base64 format it matches the original RSA XML

  Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
        Dim PBytes() As Byte = RSAGetP(txtPrivateKey.Text)
        Dim PValue As New BigInteger(PBytes)
        Dim QBytes() As Byte = RSAGetQ(txtPrivateKey.Text)
        Dim QValue As New BigInteger(QBytes)
        Dim MBytes() As Byte = RSAGetM(txtPrivateKey.Text)
        Dim MValue As New BigInteger(MBytes)
        TextBox1.Text = PValue.ToString
        TextBox2.Text = QValue.ToString
        TextBox3.Text = MValue.ToString
    End Sub

Solved the issue with the following function. The Byte Order is backwards to what Biginteger wants

    Function PrepareRSA(Bytes() As Byte)
        Array.Reverse(Bytes)
        If (Bytes((Bytes.Length - 1)) > 127) Then
            Array.Resize(Bytes, (Bytes.Length + 1))
            Bytes((Bytes.Length - 1)) = 0
        End If
        Return Bytes
    End Function
