C# Language Comments


Example

Using comments in your projects is a handy way of leaving explanations of your design choices, and should aim to make your (or someone else's) life easier when maintaining or adding to the code.

There are a two ways of adding a comment to your code.

Single line comments

Any text placed after // will be treated as a comment.

public class Program
{
    // This is the entry point of my program.
    public static void Main()
    {
        // Prints a message to the console. - This is a comment!
        System.Console.WriteLine("Hello, World!"); 

        // System.Console.WriteLine("Hello, World again!"); // You can even comment out code.
        System.Console.ReadLine();
    }
}

Multi line or delimited comments

Any text between /* and */ will be treated as a comment.

public class Program
{
    public static void Main()
    {
        /*
            This is a multi line comment
            it will be ignored by the compiler.
        */
        System.Console.WriteLine("Hello, World!");

        // It's also possible to make an inline comment with /* */
        // although it's rarely used in practice
        System.Console.WriteLine(/* Inline comment */ "Hello, World!");
  
        System.Console.ReadLine();
    }
}
