C# Hello World

"Hello, World !!" program in C# is a great way to start for beginners. Here's a simple example:

 

using System;

class Program
{
    static void Main()
    {
        Console.WriteLine("Hello, World !!");
    }
}

 

Now, let's break it down:

  • using System;: This line tells the compiler to include the System namespace, which contains essential classes like Console for input and output operations.

 

  • class Program: Defines a class named Program. In C#, the entry point of the program is within a class.

 

  • static void Main(): This is the entry point of the program. It's a method named Main that serves as the starting point for the program. The static keyword means that the method belongs to the class itself, not to instances of the class. void indicates that the method doesn't return any value.

 

  • Console.WriteLine("Hello, World!");: This line prints the string "Hello, World!" to the console. The Console.WriteLine method is used to display text, and the semicolon ; indicates the end of the statement.

 

To run this program, you can use an integrated development environment (IDE) like Visual Studio or a text editor with the .NET SDK installed.

 

Save the code in a file with a .cs extension, and then compile and run it using the following commands:

 

csc YourFileName.cs
YourFileName.exe

 

Replace YourFileName with the actual name of your C# file. This will compile and execute your "Hello, World!" program.
