C#基础_类的声明

新建Clerk类。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace 类的声明
{
public enum Gender
{
男,
女,
}
class Clerk
{
//类中可以存放字段，存放属性和方法
public string _name;//字段，命名规范，下划线加驼峰命名法
//字段可以存放多个值，变量只能存放一个值
public Gender _gender;
public int _age;
public string _department;
public int _workYears;

//静态方法只能调用静态成员
//非静态方法可以调用任何成员
public void Write()
{
Console.WriteLine("我叫{0},我是{1}生，今年{2}岁，我在{3}任职，我工作了{4}年",_name,_gender,_age,_department,_workYears);
}
}
}

使用类

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace 类的声明
{
class Program
{
static void Main(string[] args)
{
//将类实例化，就是将类指定黑给某个对象
Clerk zsClerk = new Clerk();
zsClerk._name = "张三";
zsClerk._gender = Gender.男;
zsClerk._age = 22;
zsClerk._department = "电气部";
zsClerk._workYears = 3;
string name = "111";
//调用非静态方法
zsClerk.Write();

Clerk lsClerk = new Clerk();
lsClerk._name = "李四";
lsClerk._gender = Gender.男;
lsClerk._age = 24;
lsClerk._department = "软件部";
lsClerk._workYears = 2;
name = "222";
lsClerk.Write();

Console.WriteLine(zsClerk._name);//字段
Console.WriteLine(lsClerk._name);//字段
Console.WriteLine(name);
Console.WriteLine(name);
//字段可以存放多个值，变量只能存放一个值

Console.ReadKey();
}
}
}
