Singleton Pattern for C# [closed]

Answer 1

A Singleton isn't just a static class that can't be inherited. It's a regular class that can be instantiated only once, with everybody sharing that single instance (and making it thread safe is even more work).

The typical .NET code for a Singleton looks something like the following. This is a quick example, and not by any means the best implementation or thread-safe code:

public sealed class Singleton
{
    Singleton _instance = null;

    public Singleton Instance
    {
        get
        {
            if(_instance == null)
                _instance = new Singleton();

            return _instance;
        }
    }

    // Default private constructor so only we can instanctiate
    private Singleton() { }

    // Default private static constructor
    private static Singleton() { }
}

If you're going to go down the path you're thinking, a static sealed class will work just fine.
