C# Hello World Program

The "Hello World" program is the simplest C# program that outputs the text Hello, World! to the console. It’s a great way to get started with C# and understand how the basic structure works.

Code Example:

using System;

namespace HelloWorldApp
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Hello, World!");
        }
    }
}
  

How this program works:

• using System; imports the System namespace which provides basic functionality like input/output.
• namespace HelloWorldApp organizes the code and prevents name conflicts.
• class Program declares a class named Program, which contains the program code.
• static void Main(string[] args) is the entry point where the program starts executing.
• Console.WriteLine("Hello, World!"); prints the text Hello, World! to the console.

Run this program in any C# IDE or compiler, and you will see Hello, World! displayed on the screen.
