c# switch when

/*
	Why use many "if" statements if you can just use a switch
	and clean alot of your code!

	Below are two ways to make your life alot easier!
*/

// Using a traditional switch statement

string test = "1";
switch (test)
{
	case "*":
		Console.WriteLine("test");
		break;

	case "Something else":
		Console.WriteLine("test1");
		break;

	case string when test != "*":
		Console.WriteLine("test2");
		break;

  	default:
	Console.WriteLine("default");
		break;
}

// Using a switch expression
// This obviously results in much cleaner code!

string result = test switch
{
	"*" => "test",
	"test" => "test1",
	string when test != "*" => "test2",
	_ => "default" // In switch expressions the _ is the same as default
};

Console.WriteLine(result);
