Sure! Comments in C# are used to add explanations or notes within your code that are ignored by the compiler. They are helpful for making your code more understandable to yourself and others who might read it. Here's how you can use comments in C#:
Single-line comments start with // and continue until the end of the line. They are used for short explanations or comments on a single line.
Example
// This is a single-line comment
int x = 5; // Assigning a value to variable x
Multi-line comments start with /* and end with */. They can span multiple lines and are useful for longer explanations or commenting out blocks of code.
Example
/*
This is a multi-line comment.
It can span across multiple lines.
*/
int y = 10; // This line of code is not part of the multi-line comment
/*
int z = 15;
Console.WriteLine(z);
*/
// The above block of code is commented out and won't be executed
XML documentation comments start with /// and are used to provide documentation for classes, methods, properties, etc. These comments are processed by tools like Visual Studio to generate documentation.
Example
/// <summary>
/// This method adds two integers and returns the result.
/// </summary>
/// <param name="a">The first integer.</param>
/// <param name="b">The second integer.</param>
/// <returns>The sum of the two integers.</returns>
public int Add(int a, int b)
{
return a + b;
}
That's it! Comments are a valuable tool for improving the readability and maintainability of your C# code.
