Is it possible to wrap a C# singleton in an interface?

Question

I currently have a class in which I only have static members and constants, however I\'d like to replace it with a singleton wrapped in an interface.

But how can I do th

Answer 1

You can't do this with interfaces since they only specify instance methods but you can put this in a base class.

A singleton base class:

public abstract class Singleton where ClassType : new()
{
  static Singleton()
  {
  }

  private static readonly ClassType instance = new ClassType();

  public static ClassType Instance
  {
    get
    {
      return instance;
    }
  }
}

A child singleton:

class Example : Singleton
{
  public int ExampleProperty { get; set; }
}

A caller:

public void LameExampleMethod()
{
  Example.Instance.ExampleProperty++;
}
