Program Structure

  1. Program Structure

Program Structure

A C# file is organized into namespaces, classes, and methods, with Main acting as the program's entry point. Statements inside Main execute top to bottom. Understanding this structure is essential before writing anything more complex than Hello World.

Note: Only one Main method is allowed to be the entry point of an executable project.

Example: Program Structure

markup 
using System;

class Program
{
    static void Main(string[] args)
    {
        Console.WriteLine("Program started");
        Greet();
        Console.WriteLine("Program finished");
    }

    static void Greet()
    {
        Console.WriteLine("Hello from a helper method!");
    }
}
