C# Simple Program:

A simple C# program demonstrates the basic structure of C# code, including the ‘Main’ method, which serves as the entry point for execution.

Example:

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

Using System:

‘using System;’ is used to include the ‘System’ namespace, providing access to essential classes and methods like ‘Console’ for input/output operations.

Example:

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

Using Public Modifier:

The ‘public’ modifier is used to make a class, method, or variable accessible from any part of the program. It's essential for creating reusable and accessible code components.

Example:

public class Calculator
{
    public int Add(int a, int b)
    {
        return a + b;
    }
}
class Program
{
    static void Main()
    {
        Calculator calculator = new Calculator();
        int result = calculator.Add(5, 3);
        Console.WriteLine("Result: " + result);
    }
}

Using Namespace:

Namespaces are used to organize code into logical groups. By declaring your own namespace, you can encapsulate and structure your code for better maintainability.

Example:

namespace MyApplication
{
    class Program
    {
        static void Main()
        {
            Console.WriteLine("Inside MyApplication namespace.");
        }
    }
}
namespace AnotherNamespace
{
    class Program
    {
        static void Main()
        {
            Console.WriteLine("Inside AnotherNamespace namespace.");
        }
    }
}
