Property

【Interface Property】

　　Properties can be declared on an interface (C# Reference). 

　　

　　按如下形式实现interfac来避免冲突。

　　

　　在没有interface前缀的情况下，编译器不会报错，2个interface引用同一方法：　　

class Test 

{

    static void Main()

    {

        SampleClass sc = new SampleClass();

        IControl ctrl = (IControl)sc;

        ISurface srfc = (ISurface)sc;



        // The following lines all call the same method.

        sc.Paint();

        ctrl.Paint();

        srfc.Paint();

    }

}





interface IControl

{

    void Paint();

}

interface ISurface

{

    void Paint();

}

class SampleClass : IControl, ISurface

{

    // Both ISurface.Paint and IControl.Paint call this method. 

    public void Paint()

    {

        Console.WriteLine("Paint method in SampleClass");

    }

}



// Output:

// Paint method in SampleClass

// Paint method in SampleClass

// Paint method in SampleClass

View Code

　　为每个interface实现不同的方法可以按如下这样：

public class SampleClass : IControl, ISurface

{

    void IControl.Paint()

    {

        System.Console.WriteLine("IControl.Paint");

    }

    void ISurface.Paint()

    {

        System.Console.WriteLine("ISurface.Paint");

    }

}

　　访问器可以为virtual，这也意味着可以override：

public class Parent

{

    public virtual int TestProperty

    {

        // Notice the accessor accessibility level.

        protected set { }



        // No access modifier is used here.

        get { return 0; }

    }

}

public class Kid : Parent

{

    public override int TestProperty

    {

        // Use the same accessibility level as in the overridden accessor.

        protected set { }



        // Cannot use access modifier here.

        get { return 0; }

    }

}
