Get current system setting's fraction separator

Question

In my app I parse a value from xml (string) to a double. The value in the xml happens to have the dot as a fraction seperator whereas the system takes the current system settings and can have a different separator (dev system takes the comma for example).

Is there a way to tell double.TryParse() the dot is the fraction separator?
Should I manually replace the dot with the system's fraction separator? If so, how do I get this?

Answer 1

Pass CultureInfo.InvariantCulture into double.TryParse:

double value;
bool success = double.TryParse(text, NumberStyles.Float,
                               CultureInfo.InvariantCulture,
                               out value);

(For genuinely standard XML formatting, Frederik's suggestion of using XmlConvert is the best idea though.)

Answer 2

What you should do, in this situation, is use the XmlConvert class and its members to convert the value like it exists in the XML file to a regular variable. :)
