Hello World C# Console Application

To create a “Hello World” program in C# using a console application, follow these steps:

1. Open Visual Studio and create a new project.
2. Choose “Console Application” from the available templates.
3. Give your project a name and click “Create”.
4. In the Solution Explorer, open the file “Program.cs”.
5. In the “Main” method, type the following code:

Console.WriteLine("Hello, World!");
Console.ReadKey();

The first line of code writes the message “Hello, World!” to the console. The second line waits for the user to press a key before closing the console window.

6. Build and run your program by clicking on the “Start” button in the toolbar.

When you run the program, the message “Hello, World!” will be displayed in the console window.

Here’s a breakdown of the code:

Console.WriteLine("Hello, World!");

This line of code writes the message “Hello, World!” to the console window. The Console class is a built-in class in C# that provides methods for interacting with the console. The WriteLine method writes a string of text to the console followed by a newline character.

Console.ReadKey();

This line of code waits for the user to press a key before closing the console window. The ReadKey method reads the next key pressed by the user and returns a ConsoleKeyInfo object. Since we are not doing anything with the ConsoleKeyInfo object, we can ignore the return value and just call the method to pause the program.
