double.Parse comma seperator indep.

[Jesper Denmark]

Hi,

I use the double.Parse functionality to convert a number
in a text file into a double. However, while this works
fine on one computer it doesn't on another. I've found
out that it is dependent on the comma seperator settings
on the computer. Is there a way to override this - I
would like double.Parse to always use a . as comma
seperator no matter what the system settings are.

Thanks
Jesper

Well, what you WANT it to do is irrelevant, Parse is SUPPOSED to obey system
settings.

Use another convertion means (like te Convert class), or set the thread's
culsture settings explicitly.

Well, Thomas could be right, but I thought you could go:

double.Parse("< your string to parse here>", CultureInfo.Inv ariantCulture)

which would use the settings that you used when you wrote the code and not
the user's cultural settings. I could be wrong, but if that doesn't work
you might look into the IFormatProvider interface.

Hope this helps,
Jacob

By "comma separator settings" do you actually mean the decimal
separator?

Use the form of Double.Parse which takes an IFormatProvider , and give
it CultureInfo.Inv ariantCulture, eg:

double d = Double.Parse (myString, CultureInfo.Inv ariantCulture);

Well, the version of Parse which doesn't take an IFormatProvider is...

Changing the thread's culture setting sounds like a really bad idea to
me - just passing in the appropriate culture to the overload of Parse
which takes an IFormatProvider is far cleaner, IMO.
