MyBaseC是一个抽象类,因为它有abstract修饰,它含有1个抽象方法MyMethod,注意,因为它是抽象类中的抽象方法,所以我们不需要对它做具体实现,就好比接口中定义的方法一样。它还有两个抽象属性,同样,我们不需要对他们进行具体的实现。 其实从这里,我们其实已经可以看出抽象方法(abstract method)和虚方法(virtual method)的...
因为,C# 中,不区分继承,还是实现。无论是 abstract class,还是 interface,.net 都采用相同语法。这样做可以理解,但这也会隐藏事物的本质。而 Java 区分得很清楚,继承 extends 类,实现 implement 接口。如下所示,定义抽象类 M 和接口 IM。 abstractclassM { abstractvoidMethod(); } interfaceIM { voidMethod(...
Interface: 1. An interface can contain fields, but these are implicitly static and final. 2. You can choose to explicitly declare the methods in an interface as public, but they are public even if you don’t say it. 3. Interface cannot define static method Abstract: 1. 一个类中如果所有...
interfaceI{voidM(); }abstractclassC:I{publicabstractvoidM(); } 示例2 在此示例中,类DerivedClass派生自抽象类BaseClass。 抽象类包含抽象方法AbstractMethod,以及两个抽象属性X和Y。 C# // Abstract classabstractclassBaseClass{protectedint_x =100;protectedint_y =150;// Abstract methodpublicabstractvoidAb...

This feature enables an interface to define static members. This enables interfaces to define operators that must be provided by implementing types.
This method is provided so that this class can implement the CharSequence interface. Java documentation for java.lang.AbstractStringBuilder.subSequence(int, int).

interfaceI{voidM(); }abstractclassC:I{publicabstractvoidM(); } Example 2 In this example, the classDerivedClassis derived from an abstract classBaseClass. The abstract class contains an abstract method,AbstractMethod, and two abstract properties,XandY. ...
If you have not implemented a virtual member (method/property) of the base class by overriding and have implemented the method using new keyword then the error mentioned in [2] is not faced. References Abstract (C# Reference): https://docs.microsoft.com/...
