Globalization .net convert string to double

Question

İ have string like this and i want to convert it to double.

string x = "65.50";
double y = Convert.ToDouble(x);

But the result is 6550.0

i want it to be 65.50.

I am using ASP.NET and C#. I think it is a problem about globalization.

This is my for question sorry about that (:

Answer 1

Yes, it's your current culture that converts it this way. You can use CultureInfo.InvariantCulture to skip using your culture.

double d = double.Parse("65.50", CultureInfo.InvariantCulture);

i want it to be 65.50.

If you want to convert it back to string:

string str = d.ToString("N2", CultureInfo.InvariantCulture);  

I assume this is a currency since you keep the decimal places. Then you should use decimal instead:

decimal dec = decimal.Parse("65.50", CultureInfo.InvariantCulture); // 65.5

Now you can use decimal.ToString and it automagically restores the decimal places:

string str = dec.ToString(CultureInfo.InvariantCulture); // "65.50"

Answer 2

Recently i had a similar problem. The solution :

var result = Double.TryParse(x, NumberStyles.AllowDecimalPoint, CultureInfo.InvariantCulture, out y);

if you get true, that's x is converted to double

Answer 3

Try this:

var res =  Double.Parse("65.50", NumberStyles.Float, CultureInfo.InvariantCulture);

It will parse it with culture where . is floating separator
