Arabic Problem Replace أً with just ا

Question

How to replace the alf bel tanween with a normal alf

Answer 1

Thanks to Bolo's enlightment after a couple of minutes of searching i did it like that:

string s = "";
        foreach (Char c in x)
        {
            if (((int)c).ToString("x").ToLower() != "64b")
                s += c.ToString();

        }

where x is my string

Like that I excluded the ARABIC FATHATAN from the string
