Question

I am reading a value from my App.config; which is:

 <add key="someValue" value="0.05"/>

And I try to convert it to double by doing:

 var d = double.Parse(ConfigurationManager.AppSettings["someValue"]);

And I obtain 5.0 insteads of 0.05.

Can you advice? What do I do wrong and how should I parse this?

Answer 1

That’s for your culture settings, Test the same but with a comma instead a point and you will see that work’s

var d = double.Parse("0,05");

To fixed this problem you could used the follow overload of the parse function

var d = double.Parse(ConfigurationManager.AppSettings["someValue"], CultureInfo.InvariantCulture);
