C#结构体的使用

C#结构体的使用

结构体：相当于是我们自己定义的一种复杂的类型。

常见简单类型：int... double float bool char string

常见复杂类型：DateTime 数组类型

生活中大部份的对象都是复合型的对象。

如何定义结构体类型？

一般来说结构体的定义要放在class的外面或class的里面，尽量不放在Main的里面。
struct 自定义类型名
{
    public 变量类型变量名;
    ......;
    ......;
    ......;

}
例如：
    struct YuanGong //自定义的数据类型。用来描述员工的信息。
    {
        public string NO;
        public string Name;
        public int Age;
        public string Nation;
        public bool Sex;
    }

如何用自定义的类型来定义变量？

自定义类型名变量 = new 自定义类型名();

如何使用自定义类型的变量？
变量.子变量 = "xxxx";
Console.WriteLine(变量名.子变量);
例如：
            //定义自定义类型的变量
            YuanGong zhangsan = new YuanGong();
            //给变量赋值
            zhangsan.NO = "Y001";
            zhangsan.Name = "张三";
            zhangsan.Age = 22;
            zhangsan.Sex = true;
            zhangsan.Nation = "汉族";
            //对变量取值
            Console.WriteLine(zhangsan.NO+"\t"+zhangsan.Name+"\t"+zhangsan.Age);
            Console.WriteLine(zhangsan.Nation+"\t"+(zhangsan.Sex?"男":"女"));

例题1.描述员工信息

struct YuanGong  //自定义的数据类型。用来描述员工的信息。
    {
        public string NO;
        public string Name;
        public int Age;
        public string Nation;
        public bool Sex;
        public LianXiFangShi LianXi;
    }
    struct LianXiFangShi
    {
        public string QQ;
        public string WeiXin;
        public string Email;
        public string Telephone;
        public string Address;
        public string ZipCode;
    }
    class Program
    {
        static void Main(string[] args)
        {
            YuanGong zhangsan = new YuanGong();
            zhangsan.NO = "Y001";
            zhangsan.Name = "张三";
            zhangsan.Age = 22;
            zhangsan.Sex = true;
            zhangsan.Nation = "汉族";
            zhangsan.LianXi.QQ = "434354546";
            //zhangsan.LianXi.WeiXin = "张三三";
            //zhangsan.LianXi.Email = "zhangsan@tom.com";
            zhangsan.LianXi.Address = "张店区张家胡同";
            zhangsan.LianXi.ZipCode = "25000";
            zhangsan.LianXi.Telephone = "";

            YuanGong lisi = new YuanGong();
            lisi.NO = "Y002";
            lisi.Name = "李四";
            lisi.Age = 25;
            lisi.Sex =false;
            lisi.Nation = "回族";


            Console.WriteLine("**********张三的个人信息***********");
            Console.WriteLine(zhangsan.NO+"\t"+zhangsan.Name+"\t"+zhangsan.Age);
            Console.WriteLine(zhangsan.Nation+"\t"+(zhangsan.Sex?"男":"女"));
            Console.WriteLine("联系方式：");
            Console.WriteLine(
                "QQ："+(zhangsan.LianXi.QQ==null?"无":zhangsan.LianXi.QQ)+"\t"//若没输入qq，打印“无”
                +"微信："+(zhangsan.LianXi.WeiXin == null?"无":zhangsan.LianXi.WeiXin)+"\t"
                +"手机："+(zhangsan.LianXi.Telephone==null?"无":zhangsan.LianXi.Telephone)+"\t"
                +"邮箱："+(zhangsan.LianXi.Email==null?"无":zhangsan.LianXi.Email)+"\t"
                +"地址："+zhangsan.LianXi.Address+"\t"+zhangsan.LianXi.ZipCode);
