how to set default culture info for entire c# application

Question

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

For example in Turkey 3,2 = in english 3.2

so application uses my local 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

I have to add that the non-invariant versions of .ToString() are much slower, and that "Thread.CurrentThread.CurrentCulture" does not make a difference. — gatopeich, Jun 14 '13 at 15:13

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"))

i am not really interested in defining for each transition. isn't that possible to set it for the form thread. you know when you create a new window form project ? – Furkan Gözükara Nov 13 '12 at 01:16

ok i found how to make : System.Threading.Thread.CurrentThread.CurrentUICulture = new CultureInfo("en-US", false); System.Threading.Thread.CurrentThread.CurrentCulture = new CultureInfo("en-US", false); – Furkan Gözükara Nov 13 '12 at 01:19

With 4.0, you will need to manage this yourself by setting the culture for each thread as Alexei describes. But with 4.5, you can define a culture for the appdomain and that is the preferred way to handle this. The relevant apis are CultureInfo.DefaultThreadCurrentCulture and CultureInfo.DefaultThreadCurrentUICulture.

If you use a Language Resource file to set the labels in your application you need to set the its value:

CultureInfo customCulture = new CultureInfo("en-US");
Languages.Culture = customCulture;
