Is there a way of setting culture for a whole application? All current threads and new threads?
We have the name of the culture stored in a database, and when our application starts, we do
CultureInfo ci = new CultureInfo(theCultureString);
Thread.CurrentThread.CurrentCulture = ci;
Thread.CurrentThread.CurrentUICulture = ci;
In .NET 4.5, you can use the
CultureInfo.DefaultThreadCurrentCulture property to change the culture of an AppDomain.
For versions prior to 4.5 you have to use reflection to manipulate the culture of an AppDomain. There is a private static field on
m_userDefaultCulture in .NET 2.0 mscorlib,
s_userDefaultCulture in .NET 4.0 mscorlib) that controls what
CurrentCulture returns if a thread has not set that property on itself.
This does not change the native thread locale and it is probably not a good idea to ship code that changes the culture this way. It may be useful for testing though.
