Convert - Bytes[i / 2] = Convert.ToByte(hex.Substring(i, 2), 16)

See where my vb.net equivalent of a working c# assignment statement is not working?

bytes(i / 2) = Convert.ToByte(hex.Substring(i, 1), 16)

Here's the c# followed by the vb.net function.

private byte[] StringToByteArray(String hex)
{
int NumberChars = hex.Length;
byte[] bytes = new byte[NumberChars / 2];

[CODE]...

And the vb.net that is throwing the error within the for loop

Private Function StringToByteArray(ByVal hex As String) As Byte()
Dim NumberChars As Int16 = CShort(hex.Length)

[CODE]...
