I saw this today on StackOverflow, all credit goes to Jon Skeet. I have always used RegEx or loops to check for special chars. This is a more human-friendly way of doing it.

 

Code Snippet

1. using System;
2.  
3. class Program
4. {
5.     //field
6.     private static readonly char[] SpecialChars = "!@#$%^&*()".ToCharArray();
7.  
8.     static void Main(string[] args)
9.     {
10.         //text to search for
11.         string text = "michael";
12.         int indexOf = text.IndexOfAny(SpecialChars);
13.  
14.             if (indexOf == -1)
15.             {
16.                 Console.WriteLine("no special char");
17.             }
18.  
19.             Console.ReadLine();
20.     }
21. }
