Modifiers are nothing but special keywords in C# that are used to declare how a specific method, property, or variable could be accessible. In this section, we will discuss modifiers and discuss their usage with the use of code examples.
Note
The whole point of modifiers is encapsulation. It's about how objects get simplified by encapsulations, and modifiers are like knobs saying how much you want to show to some clients, and how much not to. To understand encapsulation, refer to day seven, Encapsulation.
Access modifiers tell us how and where a member, declared type, and so on can be accessed or available. The following discussion will give you a broader idea of all access modifiers and accessibility levels.
