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 = "[email protected]"; 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); }
