用这个访问c#中的单例类；

public class Singleton
{
    private static Singleton instance;
    private static readonly object lockObject = new object();

    private Singleton()
    {
        // 私有构造函数，防止外部实例化
    }

    public static Singleton Instance
    {
        get
        {
            if (instance == null)
            {
                lock (lockObject)
                {
                    if (instance == null)
                    {
                        instance = new Singleton();
                    }
                }
            }
            return instance;
        }
    }

    public void SomeMethod()
    {
        // 单例类的其他方法
    }
}

Singleton instance = Singleton.Instance;
instance.SomeMethod();
