Writing double in console C#

I need your help about C#. I'm creating this program: 

static void Main()
    {
        Console.WriteLine("You weight is: ");
        double weight = Double.Parse(Console.ReadLine());
        Console.WriteLine("Your weight on Moon is: + {0}",weight*0.17);
     }

And the problem is, when I start the program and input, for example 35.9, a number for the weight, the program crashes.

Thanks for all of your help. I found out that in my general computer settings i have chosen comma as a decimal symbol and when i wrote in the console i used full stop. So this is the reason why it closes. :)

Try this code it'll definitely work:

Console.WriteLine("You weight is: ");
double weight;
double.TryParse(Console.ReadLine(), out weight);
Console.WriteLine("Your weight on Moon is: + {0}", weight * 0.17);

If you put breakpoints through the program, you can see it writes to the console, you just don't get an opportunity to see it.

Wait for a key using this:

Console.WriteLine("Press any key to exit");
ConsoleKeyInfo c = Console.ReadKey();

It doesn't crash. It closes.

You need to place Console.ReadLine() at the end of the method if you want the window to stay open long enough to read the message.

static void Main()
{
    Console.WriteLine("You weight is: ");
    double weight = Double.Parse(Console.ReadLine());
    Console.WriteLine("Your weight on Moon is: + {0}",weight*0.17);

    Console.ReadLine();  // waits for input, allowing you to read the message
 }
