Humm... try this:

Code Snippet

int GetIndexOfLetter(string word)

{

for (int i = 0; i < word.Length; i++)

if (Char.IsLetter(word[i]))

return i;

// this word don't have letters...

return -1;

}

Try following example :

String s = "123:qawqewtey-$";

Regex r = new Regex("[a-zA-Z]");
MessageBox.Show(r.Match(s).Index.ToString());

Regex r2 = new Regex("[@#$%]");
MessageBox.Show(r2.Match(s).Index.ToString());

put any symbol you want to look for between [] in Regex's constructor. This should work for you.
