public override void OnMouseDown(int Button, int Shift, int X, int Y),void下面出现红线
你要确定以下两点，
1，这个方法所在的类是否继承自另一个类。
2.，该类的基类不否有一个public static void OnMouseDown的方法。

范罗氟氯： A b = new B(); //注意这里,你new的是子类B,所以b不能称之为父类A的实例 A c = new C(); // 同上 b.Show(); //这里的b实际上是子类B的实例,所以调用的show方法是在B类里重写后的方法 c.Show(); //同上如果你想调用A类里的方法就不能那样写,要这样写: A b = new A(); A c = new A(); b.Show(); c.Show(); 这样输出的结果就是:A.Show() A.Show() 如果看不明白,可以再问我
呼伦贝尔市17565029050： c# 中 override 什么作用 - ？
范罗氟氯： Public abstract class A {public string TestMethod(){return ＂返回一个字符串＂;} } public class B:A {public override string TestMethod(){//blablablabla....} } Override就是来重写基类的方法的,可以实现面向对象的多态这个特性
呼伦贝尔市17565029050： Java中的@Override是什么意思? - ？
范罗氟氯： @Override是伪代码,表示重写(当然不写也可以) 建议写上,有如下好处: 1、可以当注释用,方便阅读; 2、编译器可以给你验证@Override下面的方法名是否是你父类中所有的,如果没有则报错,比如你如果没写@Override而你下面的方法名又写错了,这时你的编译器是可以通过的(它以为这个方法是你的子类中自己增加的方法).
呼伦贝尔市17565029050： c#里面的override和new究竟有什么区别啊 - ？
范罗氟氯： override是重载所继承的类型方法的 而被继承的类方法必须加virtual 才可以被重载 new 运算符 1.用于创建对象和调用构造函数 例:Class_Test MyClass = new Class_Test(); 2.也用于为值类型调用默认的构造函数 例:int myInt = new int(); myInt 初...
呼伦贝尔市17565029050： C#中的virtual和override的用法 - ？
范罗氟氯： overrride表示重写 这个类是继承于Shape类 <br>public override double Area 这个属性再shape中肯定存在 但是这里我们不想用shape中的 所以要重写 virtual是告诉其它想继承于他的类 你可以重写我的这个方法或属性,否则不允许. 给你一个生动的例子 老爸表示基类(被继承的类) 儿子表示子类(继承的类) 老爸用virtual告诉儿子:＂孩子,你要继承我的事业,在这块上面可以自己继续发展你自己的＂ 儿子用override告诉全世界:＂这个我可不是直接拿我爸的,他只是指个路给我,是我自己奋斗出来的＂
呼伦贝尔市17565029050： asp.net中override是什么意思,什么时候可以用?有什么作用? - ？
范罗氟氯： 一般是实现虚方法的时候需要的关键字 [虚方法声明关键字virtual] 要扩展或修改继承的方法、属性、索引器或事件的抽象实现或虚实现,必须使用 override 修饰符 比如:class TestOverride { public class Employee { public string name; // Basepay ...
呼伦贝尔市17565029050： C#中 override和new关键字的区别 - ？
范罗氟氯： 建一个控制台工程,复制一下代码:using System; using System.Collections.Generic; using System.Text; namespace ConsoleApplication1 { public class A { public virtual void MethodA() { Console.WriteLine(＂A.MethodA＂); } public void MethodB...
呼伦贝尔市17565029050： C#的override怎么用? - ？
范罗氟氯： override 方法提供从基类继承的成员的新实现. 由 override 声明重写的方法称为重写基方法. 重写的基方法必须与 override 方法具有相同的签名. 有关继承的信息,请参见继承(C# 编程指南).不能重写非虚方法或静态方法. 重写的基方法...
呼伦贝尔市17565029050： 怎么在android中实现一个按钮的多个监听事件 - ？
范罗氟氯： 1、先申明一个监听对象2、不同按钮设置同一个监听对象3、监听中,通过按钮的id判断是哪个按钮的点击事件 代码如下1、new监听 OnClickListener clickListener = new OnClickListener(){ @Override public void onClick(View v) { if (v.getId()==R.id....
呼伦贝尔市17565029050： android button 双击操作如何监听 - ？
范罗氟氯： android里面没有监听双击事件的操作,如果想实现的话我的建议是在 private int count = 0; button.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {count++;if(cout == 2){.监听处理.count = 0;}} }) ; 这样...
