Inheritance of interfaces

inherited interface should be accessible, such as inheriting from a private type or an interface of internal type, which is not allowed. Interfaces do not allow you to inherit directly or indirectly from yourself. Similar to the inheritance of a class, the inheritance of an interface forms a hierarchy between interfaces. Take a look at the example below. Program Listing 15-1: Using System; Interface icontrol { void Paint (); } Interface Itextb

Paint call this method.Public VoidPaint (){}} However, if two interface members execute different functions, this may result in incorrect implementation of one of the interfaces or incorrect implementation of both interfaces. You can expli

C # Language Specification--1.9 interface

Specification | interface An interface defines a contract. A class or struct that implements an interface must comply with its contract. Interfaces can contain methods, properties, indexers, and events as members. Example Interface Iexample{String This[int index] {get; set;}Event EventHandler E;void F (int value);String P {get; set;}}public delegate void EventHandler (object sender, EventArgs e); Shows an interface that contains indexers, event E, Method F, and property P. Interfaces can use mul

. In Java, a method definition can have a public modifier (even if this is not necessary), but in C #, it is illegal to explicitly specify the public modifier for the method of an interface. For example, the following C # interface will produce a compilation error.Interface IShape {public void Draw ();}The following example defines an interface named IControl that contains a member method paint:Interface IControl

Example:Interface Imyexample {String This[int index] {get; set;}Event EventHandler even;void Find (int value);String point {get; set;}}public delegate void EventHandler (object sender, Event e);The interface in the example above contains an index of this, an event even, a method find, and a property point.Interfaces can support multiple inheritance.

the lifecycle of a range or reference computing (consistent with brew ). One solution used in previous articles is to register the object and bind the object cycle with the Registry cycle. This means you need to add a layer (Registry) and be able to track all resources in a certain place. The C ++ application directly created on BREW is not a level 1 C ++ object, but a pod structure. That is why the real C ++ operation clearly requires such an insulating layer. Next we will call our registry di

interface and access modifier layer. We all know that the Members defined in the interface do not have access modifiers. For example, if you want to add an access modifier before void doWork (), the compilation will not pass. 1: interface IControl 2: { 3: void doWork(); 4: } But why is it designed like this? At this time, someone said, isn't that nonsense! There is no need to use an access modifier for an interface. The interface
