Convert.ToDouble question

I've bought a C# book which teaches me to convert my input to a double like this:

Code:

---

double number;
number = Convert.ToDouble(Console.ReadLine());

---

When I enter something like 10.12 it gives me an error and accuses me for entering info of the wrong type.
I use Visual C# 2005 Express. Any ideas?

Code looks good.

Code:

---

static void Main(string[] args)
{
        double number;
        Console.Write("Enter a double: ");
        number = Convert.ToDouble(Console.ReadLine());
        Console.WriteLine("You entered " + number.ToString());
        Console.ReadLine();
}

---

Output:

Code:

---

Enter a double: 10.15
You entered 10.15

---

So, what exactly is the problem again?

I think I figured it out... my language setting is swedish, and in sweden we use a comma instead of a dot when we use floats like this: 10,15 instead of 10.15 and when I input that at runtime it works fine. So I guess the .NET framework adapts to different national standards... this is the only reason I can think of since it works with a comma.

Yup, sounds pretty logical to me. You can specify your culture settings in the Convert call to allow other representations.

Code:

---

static void Main(string[] args)
{
        double number;
        NumberFormatInfo numberInfo = new NumberFormatInfo();
        numberInfo.NumberDecimalSeparator = ",";
        Console.Write("Enter a double: ");
        number = Convert.ToDouble(Console.ReadLine(),numberInfo);
        Console.WriteLine("You entered " + number.ToString(numberInfo));
        Console.ReadLine();
}

Ah! Thank you for this info. I think I'll change to the more international "." since that's what I'm used to in the world of programming. Thanks again!
