using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace LearnCsharp{    class Program    {        static void Main(string[] args)        {            int a=5;            //a比大，所以输出为1            //返回的类型是整型            Console.WriteLine(a.CompareTo(3));            Console.WriteLine(a.CompareTo(3).GetType());            //a和3不等，返回类型为false            //返回类型为bool型            Console.WriteLine(a.Equals(3));            Console.WriteLine(a.Equals(3).GetType());            //把a转换为字符串            //转换后str类型为String型            string str =a.ToString();            Console.WriteLine(str);            Console.WriteLine(str.GetType());            //a的类型            //a的类型的类型，为 runtime Type            Console.WriteLine(a.GetType());            Console.WriteLine(a.GetType().GetType());            //a的类型            Console.WriteLine(a.GetTypeCode());            Console.WriteLine(a.GetTypeCode().GetType());            Console.WriteLine(a.GetTypeCode().GetTypeCode());        }    }}
