Most Used Keywords in C#

What is C#?

C# is a programming language created and sent off by Microsoft in 2001. It is a basic, modern, and object-oriented language that gives current-day developers the adaptability and elements to fabricate programming that won’t just work today yet will be relevant for long.

C# is an incredible decision for developers with moderate to cutting edge insight in writing code. While specialists recognize the language as one of the mild complexities, they agree that it's genuinely easy to grasp and excel in. Whenever you're familiar with C# and set forth the effort to get its hang, you can hope to progress rapidly from rookie to expert.

Uses of C#?

C# is a broadly helpful programming language used to build programs and applications. While it is exceptionally versatile, there are three fields where it is generally applied:

  1. Web Application Development
  2. Windows Application
  3. Games

Now, What Are Keywords?

C# is wealthy in features and keywords, which help make the language solid and adaptable. Keywords are private words with extraordinary implying that the compiler knows. These keywords also have unique importance and can’t be used as identifier names for variable-name, class-name, or interface-name. If you have to involve a keyword as an identifier, you can use @ as a prefix.

Keywords in C#


This keyword helps to add namespaces in code-behind and class files. Then it makes available all classes, interfaces, and abstract classes and their methods and properties on the current page.


Class is a keyword in C#.NET that helps make a class, and classes are unique formats from which you can create objects. Each item contains information and strategies to control and access that information, and the class characterizes the data and the usefulness that each object of that class can have.

A class declaration comprises of class header and body. The class header includes attributes, modifiers, and the class keyword. The class body embodies the members of the class, which are the data members and member functions.


Struct is an embodied element, and it doesn’t utilize a total oops idea but is used for a user-defined data type. A struct is an effortless user-defined type, a lightweight option in contrast to a class. A design in C# is just a composite information type comprising several other types. Like classes, structures have ways of behaving and attributes. Struct supports access modifiers, constructors, indexers, techniques, fields, nested types, administrators, and properties.


The interface helps in making a connection point in C#. An interface seems to be a class that can have a set of properties, techniques, occasions, and indexers but has no implementation. The interface doesn’t have an implementation of properties, methods, events, and indexers since they obtain it from classes and structs, which gives implementation for every interface member.

An Interface can conceal implementation details of classes from one another, and it permits different items to interact easily. It gives a separation among points of interface and implementation.

An Interface isn't just an authoritative commitment to implement specific strategies, properties, occasions, and records. Yet additionally gives an exceptionally low coupling between two classes. Interfaces in C# are provided as a substitution for multiple inheritances of classes because C# doesn't uphold various legacies of types. Interfaces and extract classes have similar purposes.
