Explain the basic structure of C# program with code




 
The basic structure of a C# program consists of several components. Here's an example code snippet to illustrate the structure:

 

using System;

 

namespace MyProgram

{

    class Program

    {

        static void Main(string[] args)

        {

            // Code statements go here

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

 

            // More code statements...

 

            Console.ReadLine();

        }

    }

}

 

 

1.      `using System;`: This line is called a using directive. It allows you to import namespaces from the .NET framework that provide additional functionality. In this case, we are importing the `System` namespace, which contains fundamental types and classes used in C# programs.

 

2.      `namespace MyProgram`: Namespaces are used to organize related classes and prevent naming conflicts. They provide a way to group related code together. In this example, we define a namespace called `MyProgram`.

 

3.      `class Program`: Classes are the building blocks of C# programs. Here, we define a class called `Program` within the `MyProgram` namespace.

 

4.      `static void Main(string[] args)`: This is the entry point of the program. The `Main` method is a static method, meaning it belongs to the class itself and not to an instance of the class. It's the starting point of execution when the program runs.

 

5.      `// Code statements go here`: This is where you can add your code statements. In this example, we have a single statement that prints "Hello, World!" to the console using the `Console.WriteLine` method.

 

6.      `Console.ReadLine();`: This line waits for user input before the program terminates. It prevents the console window from closing immediately after the program executes, giving you a chance to see the output.

 

To run the program, you can compile and execute the code using an IDE like Visual Studio, or you can use the .NET Core command-line tools (`dotnet build` and `dotnet run`) if you're working with a .NET Core application.
