属性在继承中的应用

{
        public class Employee1
        {
            private string name;
            public string Name
            {
                get { return name; }
                set { name = value; }
            }
        }

    public class Manager : Employee1
        {
            private string name;

            // Notice the use of the new modifier:
            public new string Name
            {
                get { return name; }
                set { name = value + ", Manager"; }
            }
        }

        class TestHiding
        {
            static void Main()
            {
                Manager m1 = new Manager();

                // Derived class property.
                m1.Name = "John";

                // Base class property.
                ((Employee1)m1).Name = "Mary";//将子类的引用转换成父类的引用此时调用的是父类的set属性

                System.Console.WriteLine("Name in the derived class is: {0}", m1.Name);
                System.Console.WriteLine("Name in the base class is: {0}", ((Employee1)m1).Name);//此时调用的是父类的get属性
            }
        }
}

当派生类的属性隐藏拉基类中的属性在子类中用new修饰符做说明；代码如下

            public new string Name
            {
                get { return name; }
                set { name = value + ", Manager"; }
            }

注：父类和子类的中的字段可以是不同名称
