I would like to collect more variants for create singleton class. Could you please provide to me the best creation way in C# by your opinion.

谢谢。

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() { }
}

哦，并且尽量避免使用单例模式，因为它的可测性等的痛苦：）

Oh, and try to avoid using the singleton pattern in general, due to its pain for testability etc :)
