.net - How to implement a singleton in C#?

Question

How do I implement the singleton pattern in C#? I want to put my constants and some basic functions in it as I use those everywhere in my project. I want to have them 'Global' and not need to manually bind them every object I create.

Answer 1

If you are just storing some global values and have some methods that don't need state, you don't need singleton. Just make the class and its properties/methods static.

public static class GlobalSomething
{
   public static int NumberOfSomething { get; set; }

   public static string MangleString( string someValue )
   {
   }
}

Singleton is most useful when you have a normal class with state, but you only want one of them. The links that others have provided should be useful in exploring the Singleton pattern.
