Conditional - SWITCH

Summary

• When we have many decisions at once, it is time to use switch.
• Executed in a cascade, walking through each configured option.
• We must stop the execution with the break command.
• It has a default execution called default.

Base structure

switch(value)
{
    case option: doSomething; break;
    //...
    default: doSomethingDefault; break;
}

Basic example

int value = 1;
switch(value)
{
    case 1: Console.WriteLine("Value is 1"); break;
    case 2: Console.WriteLine("Value is 2"); break;
    case 3: Console.WriteLine("Value is 3"); break;
    default: Console.WriteLine("Value is greater than 3"); break;
}

We can use any type of data:

string value = "Test";
switch(value)
{
    case "John": Console.WriteLine("Value is John"); break;
    case "Test": Console.WriteLine("Value is Test"); break;
    case "Pope": Console.WriteLine("Value is Pope"); break;
    default: Console.WriteLine("Unexpected value"); break;
}
