C# Keywords

In this blog, you will learn about C# Keywords.

Introduction

C# is rich in features and keywords which helps to make the language strong and versatile. Keywords are predefined sets of reserved words that have a special meaning that is known to the compiler. These keywords have special significance so that we cannot use them as identifiers for class name, variable name, and interface name. In this blog, you will learn about C# keywords.
