c# switch case

// Switch Statement VS Switch Expression
static void TrafficUsingSwitchStatement(string color)
{
    string result;

    switch (color)
    {
        case "Red":

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);

how to use switch statement in c#

/* Switch Statements are a cleaner way to write if and else statements like this: */

var randomNum = Mathf.Random.Range(0, 5);

// ofcourse this way is so dumb but its just for explaining
if (randomNum == 0) print("The correct number is 0");
else if (randomNum == 1) print("The correct number is 1");
else if (randomNum == 2) print("The correct number is 2");
else if (randomNum == 3) print("The correct number is 3");
else if (randomNum == 4) print("The correct number is 4");
else if (randomNum == 5) print("The correct number is 5");

// Instead of writing if and else statements like this we can use switch statements like this:

switch(randomNum)
{
  case 0:
    print("correct number is 0");
    break; // we must include a break statement at the end of every case.
    
  case 1:
    print("correct number is 1");
    break;
    
  case 2:
    print("correct number is 2");
    break;
    
  case 3:
    print("correct number is 3");
    break;
    
  case 4:
    print("correct number is 4");
    break;
    
  case 5:
    print("correct number is 5");
    break;
}
