Title
Body
I need to be able to say something like myString.IndexOf(c => !Char.IsDigit(c)) , but I can't find any such method in the .NET framework. Did I miss something? The following works, but rolling my own seems a little tedious here: using System; class Program { static void Main() { string text = "555ttt555"; int nonDigitIndex = text.IndexOf(c => !Char.IsDigit(c)); Console.WriteLine(nonDigitIndex); } } static class StringExtensions { public static int IndexOf(this string self, Predicate<char> predicate) { for (int index = 0; index < self.Length; ++index) { if (predicate(self[index])) { return index; } } return -1; } }
