In C#, comments are used to provide explanations and descriptions within your code. Comments are ignored by the compiler and are not executed as part of the program. They serve as documentation for developers and help improve code readability and maintainability.
C# supports two types of comments:
- Single-line comments: Single-line comments start with two forward slashes (
//) and continue until the end of the line. Anything written after//is considered a comment. For example:
// This is a single-line comment int x = 5; // Assigning a value to variable x
- Multi-line comments: Multi-line comments, also known as block comments, start with a forward slash followed by an asterisk (
/*) and end with an asterisk followed by a forward slash (*/). Anything between/*and*/is considered a comment. Multi-line comments can span multiple lines. For example:
/* This is a multi-line comment It can span multiple lines */ int y = 10; /* Assigning a value to variable y */
Comments are useful for various purposes, including:
- Explaining the purpose and functionality of a block of code.
- Providing information about the author, date, or version of the code.
- Temporarily disabling a block of code without deleting it.
It’s good practice to use comments effectively in your code to enhance its clarity and make it more understandable to other developers or even your future self.
