Types of Comments in C#

Comments in C# are crucial for explaining and documenting the code to make it easier to understand and maintain. There are several types of comments in C# which can be used according to the need and context:

Single-Line Comments

Single-line comments start with //. Anything following // on the same line is ignored by the compiler.

Example:

// This is a single-line comment
int x = 5; // This is a comment after code

Multi-Line Comments

Multi-line comments start with /* and end with */. They can span several lines and are used to comment out blocks of code or for longer explanations.

Example:

/* This is a multi-line comment
   and it can span multiple lines. */
int y = 10;

XML Documentation Comments

XML documentation comments are special comments that start with /// and are used to systematically document the code. These comments can be processed to generate external documentation, provide contextual information in the IDE, and offer IntelliSense descriptions.

Example:

/// <summary>
/// The main entry point for the application.
/// </summary>
/// <param name="args">Command line arguments</param>
public static void Main(string[] args)
{
    Console.WriteLine("Hello, World!");
}

Each type of comment serves different purposes, from simple annotations to detailed documentation that enhances the development experience.
