Control Statements in C# – if, else, switch, and loops Explained

Example

using System;

class Program
{
    static void Main()
    {
        int number = 10;

        // if-else example
        if (number > 0)
        {
            Console.WriteLine("Positive Number");
        }
        else
        {
            Console.WriteLine("Non-Positive Number");
        }

        // switch example
        switch (number)
        {
            case 10:
                Console.WriteLine("Number is 10");
                break;
            default:
                Console.WriteLine("Unknown number");
                break;
        }

        // for loop example
        for (int i = 1; i <= 5; i++)
        {
            Console.WriteLine("Count: " + i);
        }
    }
}

Summary

Control statements are crucial for creating logic in applications. if-else and switch are used for decision-making, while loops (for, while, do-while, foreach) help execute code repeatedly based on a condition.

Example

string[] colors = { "Red", "Green", "Blue" };

foreach (string color in colors)
{
    Console.WriteLine(color);
}
