如何为整个c＃应用程序设置默认文化信息

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

Answer 1

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 .

Answer 2

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"))

Answer 3

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;
