switch statement

switch (fruit)

    case "apple":
        Console.WriteLine($"App will display information for apple.");
        break;

    case "banana":
        Console.WriteLine($"App will display information for banana.");

Since cases "fall through" in c# you can use this to create multiple labels, like in c.

int employeeLevel = 100;
string title = "";

switch (employeeLevel)
{
    case 100:
    case 200:
        title = "Senior Associate";
        break;
    case 300:
        title = "Manager";
        break;
    case 400:
        title = "Senior Manager";
        break;
    default:
        title = "Associate";
        break;
}
