设计一个Time类，其包含三个字段：Hour,Minute,Second
包含带参数的构造函数，包含SetTime方法，可以设置成员变量，包含PrintTime方法，可以按如下格式打印Time(XX:XX:XX)

恩，这是个问题？
我也想知道啊！

楼主，你是问作业吗？

不好意思，我是初学者，所以连这个也不会，希望那个大虾帮帮忙！
多谢，多谢！

这个是利用属性，get和set

胡写几句，live41看看对不对^_^ using System; class Time { int Hour,Minute,Second; public Time(System.DateTime SystemTime) { this.Hour = SystemTime.Hour; this.Minute = SystemTime.Minute; this.Second = SystemTime.Second; } public void PrintTime() { Console.WriteLine("现在是 {0}:{1}:{2} ",Hour,Minute,Second); } public void SetTime(int Hour,int Minute,int Second) { this.Hour = Hour; this.Minute = Minute; this.Second = Second; } } class Test { public static void Main() { int Hour,Minute,Second; System.DateTime SystemTime = System.DateTime.Now; Time time = new Time(SystemTime);

time.PrintTime(); Console.WriteLine("重新设置时间:11:11:11"); Hour =11; Minute =11; Second =11; time.SetTime(Hour,Minute,Second); time.PrintTime(); Console.ReadLine(); } }

对啊，不过你那是C++写法，C#有属性的功能，你看看书吧。

是get{} set{}，我自己都忘了呵呵……

噢，你是指这样吗？ using System; class Time { int Hour,Minute,Second;

public Time(System.DateTime SystemTime) {

this.Hour = SystemTime.Hour; this.Minute = SystemTime.Minute; this.Second = SystemTime.Second; }

public void PrintTime() { Console.WriteLine("现在是 {0}:{1}:{2} ",Hour,Minute,Second); }

public int hour { get { return Hour; } set { Hour = value; } } public int minute { get { return Minute; } set { Minute = value; } }

public int second { get { return Second; } set { Second = value; } }

} class Test { public static void Main() { System.DateTime SystemTime = System.DateTime.Now;

Time time = new Time(SystemTime);

time.PrintTime(); Console.WriteLine("重新设置时间:11:11:11"); time.hour =11; time.minute =11; time.second =11; time.PrintTime(); Console.ReadLine(); } }
