C＃中的接口
interface
[public|protected|private] interface InterfaceName
{
//mothed
// propery
// event
//delegate
}
在实现接口时，带接口名与不带接口的区别
不带的区别eg:
public interface IMyShow
{
void Show();
}
public class MyShow:IMyShow
{
public void Show()//必须写上前的public若写成void Show()出错
{
System.Console.Write(" 不带接口名");
}
}
public class MyMain
{
public static void Main()
{
// 用类定义引用
MyShow obj=new MyShow();
obj.Show();
//用接口引用方法
IMyShow obj2=new MyShow();
obj2.Show();

}
}

//带接口名
public interface IMyShow
{
System.Console.Write("带接口名");
}
public class MyShow:IMyShow
{
void IMyShow.Show()// 前面不能带上任何限定词
{
System.Console.Write("带接口名");
}
}
public class MyMain
{
public static void Main()
{
MyShow obj=new MyShow();
obj.Show();//非法因为加了限定词后，这个方法专属于专们的一个引用，只能有接口去引用
IMyShow obj2=new MyShow();
obj2.Show();

}
}
看完上面的内容我想为C＃的爱好留个问题。请大家一起来讨论一下
public interface IMyShow
{
void Show();
}
public interface IMyShow2
{
void Show();
}

public class Myclass:IMyShow,IMyShow2
{
public Myclass()
{

}

void IMyShow.Show()
{
System.Console.Write("IMyShow");

}




public void Show()
{
System.Console.Write("Myclass show");
}

void IMyShow2.Show()
{
System.Console.Write("IMyShow2.Show()");

// TODO: 添加 Myclass.Show 实现
}


}

class Class1
{
/// <summary>
/// 应用程序的主入口点。
/// </summary>
[STAThread]
static void Main(string[] args)
{
IMyShow obj2=new Myclass ();
obj2.Show();
IMyShow obj1=new Myclass();
obj1.Show();
Myclass obj=new Myclass();
obj.Show();

}
}
}
