C# 设计模式（9）组合模式

组合模式

1. 运用递归

2. 组合模式：分透明和安全

代码实现：

项目提成

namespace CompositePattern
{
    public abstract class AbstractDomain
    {
        public string Name { get; set; }
        public int Percent { get; set; }
        public abstract void Commission(double money);
    }
    class Domain:AbstractDomain
    {
        List<Domain> domainChildList = new List<Domain>();

        public void AddChild(Domain domainChild)
        {
            this.domainChildList.Add(domainChild);
        }

        public override void Commission(double money)
        {
            double ret = money * this.Percent / 100;
            Console.WriteLine($"{this.Name} can get {ret} RMB");

            foreach (var domainChild in domainChildList)
            {
                domainChild.Commission(ret);
            }
        }
    }
}

    {
        static void Main(string[] args)
        {
            double totalMoney = 1000000;
            var domains = BuildTree();
            domains.Commission(totalMoney);
        }
