C#设计模式02——原型模式的写法

    public class ProteType
    { 

        private static ProteType _ProteType = new ProteType();
        private ProteType() { }
        public static ProteType GetInstance()
        {
            return (ProteType)_ProteType.MemberwiseClone();
        }

    }

运行测试

                var a1 = ProteType.GetInstance();
                var a2 = ProteType.GetInstance();
                Console.WriteLine($"a1 和 a2 是同一实例：{ object.ReferenceEquals(a1, a2)}");
