switch Statement

A switch is like a menu where you say the item number and get exactly that dish. C# compares one value against a list of cases and runs the one that matches.

switch Statement

Syntax

csharp

switch (value)
{
    case value1:
        // ...
        break;
    case value2:
        // ...
        break;
    default:
        // no case matched
        break;
}

switch Statement

A switch statement compares one value against several case labels and runs the matching block. Each case needs a break (or return) to prevent falling through to the next one. default handles any value that doesn't match a case.

Warning: Unlike C, C# does not allow implicit fallthrough between non-empty cases — each case must end with break, return, or goto.

Example: switch Statement

markup

using System;

class Program
{
    static void Main(string[] args)
    {
        int day = 3;
        string name;

        switch (day)
        {
            case 1:
                name = "Monday";
                break;
            case 2:
                name = "Tuesday";
                break;
            case 3:
                name = "Wednesday";
                break;
            default:
                name = "Unknown";
                break;
        }

        Console.WriteLine(name);
    }
}
