c# anonymous class

Many people may not be familiar with the inner class mentioned in Java. In fact, similar concepts also exist in C ++, that is, nested class (nestedClass). The differences and relationships between the two are compared in the following section. On the surface, an internal class defines another

Public interface contents { Int value (); } Public interface destination { String readlabel (); } Public class goods { Private class content implements contents { Private int I = 11; Public int value (){ Return I; } } Protected class gdestination implements destination { Private string label; Private gdestination (string whereto ){ Label = whereto;

Today, I saw several concepts in the Code: internal class, local class, member class, static member class, and anonymous internal class. I felt confused in an instant. Below is a small example to illustrate them: Public

create an internal class to implement this interface. Since all the content of the internal class is accessible to external departments, this can complete all the functions that you can directly implement this interface. But you may have to question it. Isn't it enough to change the method? Indeed, it is unconvincing to use this as a reason to design internal classes. The real reason is that the internal c

Anonymous Methods is one of the new features of c#2.0, which allows us to create a built-in method with no method name in the code, associate code with a delegate instance, which makes the instantiation of the delegate more intuitive and convenient, and improves the readability and maintainability of the code. Here's a simple way to use anonymous methods: Privat

Anonymous classes are classes that cannot have names, so there is no way to reference them. They must be declared as part of the new statement when they are created. This will take another form of the new statement, as follows: New Java code Copy Code code as follows: Interface PR { void Print1 (); } public class Nonameclass { Public PR Dest () { return new PR () { public v

Anonymous classes cannot be referenced because they cannot have names. They must be declared as part of the new statement at creation. This requires another form of new statement, as shown below: new Java code Copy codeThe Code is as follows: interface pr { Void print1 (); } Public class noNameClass { Public pr dest () { Return new pr (){ Public void print1 () { System. out. println ("Hello world !! "); } }
