What are Access Modifiers and the Static Modifier in C#, and How Do They Work?

In -depth understanding of the access modifier and static modifier in C#

In C#programming, you may already use the

access modification character, but the functions of other access modifiers may not know much about it. This article will explore the access modifications in C#, explain the differences between

, public, public and the non -access modification statement statement in detail, and clarify the mysterious private modification and its characteristics. protected static Access modifier: Define the boundary of access permissions

The visibility and accessability of the device control class, methods and variables in the program. C#provides a variety of access modifications:

:

Access the modifier without restrictions, allow the code that concentrates the concentration of the same sequence and reference programs to access the protected entity.
• public : The most stringent access modification format is limited to internal access to the class of the entity.
• : private Semi -private modifier, allows access to the claim, derivatives and the same sequence set.
• : The limited access is limited to the code in the same program set, and the reference program set cannot be accessed. protected
(C# 7.2 and above):
• Similar to , but the access permissions are limited to derivative classes in the same program set. internal
If there is no significant specified access to the modifier, the entity defaults to the assembly of the assembly of the assembly level level, allowing any class access in the same program set.
• Static modifier: The essence of unique nature private protected protected The modifier is a powerful tool that gives the unique attributes:

instantiated:

Static classes cannot be instantiated as non -static classes. You will not see the familiar keywords for creating static class instances.

Member: All members of the static class are static, which means that no matter how many objects are created, each member has only one version.

Construct function: static Static classes can have a static constructor. Before creating any instance or reference to static members, the static constructor will be automatically called.

Visit:
• You can directly use the class name to access static members without creating instances. new Static class is usually used as a service provider, providing convenient functions without the need to create an instance burden.
• Now, you can use these knowledge, you can confidently use access to modifiers and static classes to design and realize a strong and efficient C#application.
