C# Static Methods

A static method belongs to the class itself rather than an instance of the class. You can call a static method without creating an object of the class.

Key Points

• Can be called using the class name directly.
• Cannot access instance (non-static) members directly.
• Useful for utility or helper functions.

Example: Using Static Method

class MathHelper
{
    public static int Square(int number)
    {
        return number * number;
    }
}

class Program
{
    static void Main()
    {
        // Calling static method without creating an object
        int result = MathHelper.Square(5);
        Console.WriteLine(result);  // Output: 25
    }
}
  

Usage Tips

• Use static methods for operations that don’t depend on object state.
• Good for mathematical operations, helper functions, or factory methods.
