object oriented concepts in c#

I. Classes and objects1, JavaScript objects fall into three categories: local objects, built-in objects, and host objects.There are 15 types of local objects: Object Function Array String number Boolean Date RegExp Error evalerror rangeerrorRrefenceerror SyntaxError TypeError UirerrorThere are 2 types of built-in objects: Global MathThe host object has N: All DOM and BOM objects2, how to define a class and

No, abstract method-the most substantial meaning / purpose is to be covered by a future subclass method (over write). It is an empty method of its own.

A simple article on PHP object-oriented concepts and examples can be used as a reference for anyone who needs it. Keywords and special VariablesNew, class, extends. Everyone knows about these three items.:, The range resolution operator (also known as Paamayim Nekudotayim) or, more simply, a colon, can be used to access static members, methods, and constants. It

need to provide the code for the destructor, but instead the default destructor performs the operation automatically. However, if you need to do some important things before you delete an object instance, you should provide a specific destructor.For example, if a variable is out of range, the code cannot access it, but the variable still exists somewhere in the computer's memory. Only in. NET runtime to perform its garbage collection, the instance is

, all non-static constructors are also referred to as instance constructors.　2. Static ClassWe often want the class to contain only static members, and cannot be used to instantiate objects such as the console. A simple way to do this is to use a static class instead of setting the class's constructor to private. A static class can contain only static members and does not require an instance constructor because, by definition, it cannot be instantiated at all. However, a static class can have a
