在使用文化信息时,将数字转换为double时,我遇到了奇怪的行为.使用荷兰文化进行

static void Main(string[] args)
{
    CultureInfo cultureDutch = new CultureInfo("nl-NL");

    // Actual result --> 3,3

    Console.WriteLine("Input 3,3 --> Expected InvalidCastException");
    Console.WriteLine("Output = " + Convert.ToDouble("3,3", cultureUS));
    // Actual result --> 33

    Console.WriteLine();
    Console.WriteLine();

    System.Threading.Thread.CurrentThread.CurrentCulture = cultureUS;
    Console.WriteLine("Input 3.3 --> Expected InvalidCastException");
    Console.WriteLine("Output = " + Convert.ToDouble("3.3", cultureDutch));
    // Actual result --> 33

    Console.WriteLine("Input …
