to an abstract base class: any non-Abstract type that inherits an interface must implement all the members of the interface. The interface cannot be instantiated directly. Interfaces can contain events, indexers, methods, and attributes. The interface does not contain the implementation of methods. Classes and structures can be inherited from multiple interfaces. The interface itself can be inherited from multiple interfaces Explicit interface implementation If the class implements two in

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 Itextbox:icontrol { void SetText (string text); } Interface Ilistbox:icontrol { void Setitems (string[] it

Class and structure (C # programming guide) Describes how to use objects, classes, and structures in C.

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

1. Why interfaces are required:Software development process, a project can not be done purely by one person, then it must be accurately divided into several parts of the software, will be divided into a number of parts to different people to do, and the interface is equivalent to the connection between the slot, first by the designer to define all the interface name, interface parameters, return data type, and explain the role of the interface, the implementation of the interface is responsible

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 {void Paint ();}In the following example, the interface IInterface inherits from the two base interfaces IBase1 and IBase2:Interface Iinterface:ibase1, IBase2 {void Method1 ();void Method

;}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. As in the following example, the interface "IComboBox" inherits from "ITextBox" and "IListBox" at the same time.Interface IControl {void Paint ();}Interface Itextbox

the real C ++ operation clearly requires such an insulating layer. Next we will call our registry displayableregistry.

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 this, an event even, a method find, and a property point. interfaces can support multiple inheritance. As in the following example, the interface "IComboBox" inherits from both "ITextBox" and "IListBox". Interface IControl
