Question

我有一节课，下面是：

public Person(string name, int age)
{
    Name = name;
    Age = age;
}

宣布课程后，我有以下内容：

String OtherName;
Int OtherAge;
Person jane = new Person("Jane", 28);
OtherName = Jane.Name;
OtherAge = Jane.Age;

如何更改OtherName的值时，如何存储OtherAge和jane以及它们不会更改？

Answer 1

即使OtherName或其属性的值已更新，变量OtherAge和jane也会保留其值。

Answer 2

我在下面重构了Person类，如果名称改变，其他名称将会改变。但其他名称可能会改变，不会影响名称道具。

public class Person
    {
        public Person(string name, int age)
        {
            Name = name;
            Age = age;
        }

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


        private int age;

        public int Age
        {
            get { return age; }
            set { otherAge = age = value; }
        }

        private string otherName;

        public string OtherName
        {
            get { return otherName; }
            set { otherName = value; }
        }
        private int otherAge;

        public int OtherAge
        {
            get { return otherAge; }
            set { otherAge = value; }
        }


    }

示例：

static void Main(string[] args)
        {
            Person jane = new Person("Jane", 28);
            jane.OtherName = jane.Name;
            jane.OtherAge = jane.Age;


            jane.Name = "Dave";
            jane.Age = 30;

            Console.WriteLine(jane.Name);
            Console.WriteLine(jane.Age);
            Console.WriteLine(jane.OtherName);
            Console.WriteLine(jane.OtherAge);

            Console.ReadKey();
        }

输出：戴夫三十戴夫 30
