How to set default culture info for entire c# application?

Question

I want to set default culture info for specific class or for entire application.

For example in Turkey 3,2 = in English 3.2

So application uses my local culture but I want it to use as default:

System.Globalization.CultureInfo.InvariantCulture

How can I set it to that as default for that specific class or for entire application?

Answer 1

Not for entire application or particular class.

CurrentUICulture and CurrentCulture are settable per thread as discussed here Is there a way of setting culture for a whole application? All current threads and new threads?. You can't change InvariantCulture at all.

Sample code to change cultures for current thread:

CultureInfo ci = new CultureInfo(theCultureString);
Thread.CurrentThread.CurrentCulture = ci;
Thread.CurrentThread.CurrentUICulture = ci;

For class you can set/restore culture inside critical methods, but it would be significantly safe to use appropriate overrides for most formatting related methods that take culture as one of arguments:

(3.3).ToString(new CultureInfo("fr-FR"))
