设计模式-单例模式-C#

单例模式比较简单，就是单个实例意思！

public class SingletonPattern
{
    public void Main()
    {
        Singleton.Instance = new Singleton();
        Singleton.Instance.Print();
    }
}

public class Singleton
{
    private static Singleton _Instance;

    public static Singleton Instance
    {
        get => _Instance;
        set => _Instance = value;
    }

    public void Print()
    {
        Console.WriteLine("这是一个单例！");
    }
}

下面是调用代码：

class Program
{
        
    static void Main(string[] args)
    {
        SingletonPattern singleton = new SingletonPattern();
        singleton.Main();
    }
}
