在C#中使用if/else和switch-case之间是否有任何显着差异？

if (x > 0)
{
    Console.WriteLine("x is positive");
}
else
{
    Console.WriteLine("x is not positive");
}

switch (x)
{
    case 0:
        Console.WriteLine("x is zero");
        break;
    case 1:
        Console.WriteLine("x is one");
        break;
    default:
        Console.WriteLine("x is neither zero nor one");
        break;
}
