数据类型详解

——预定义引用类型与用户定义引用类型

 

namespace ConsoleApp4

{

    public struct Department

    {

        public string name;

        public string tel;

    }

    class Program

    {

        static void Main(string[] args)

            //预定义的引用类型

            //(1)object

        {  

            //object是所有类型的根基类

            int a = 5;

            Console.WriteLine(a);

            Department d= new Department();

            d.name = "财务部";

            Console.WriteLine(d.name);

            //(2)string

            //思考一下，为什么微软要把string设置成引用类型放堆里？？？？

            string name = "Tom";
