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);
}

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. [Www.cnjm.net]
Our registry mainly tracks resources that can be displayed and implements the idisplayable interface: [www.cnjm.net]

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".

In the following example, the istringlist Interface contains an interface for each possible type of members: A method, an attribute, an event, and an index.

Int count {Get ;}
Event stringlistevent changed;

IPv6 adoption: Challenges and Choices, and ipv6 adoption challenges
Today, many enterprises have begun to adopt IPv6 (Internet Protocol version 6th), and more countries are preparing to increase IPv6 traffic globally. As more and more devices connect to the Internet (such as smart cars, smart homes, and even smart cities), and the available IPv4 address pools quickly run out, today's network space has become more important than ever before. However, using NAT (Network Address Translation) as th
