blocks|key|350018|text|这个问题被问得很多。基本上，没有，不是针对.NET+4.0。您必须在每个新线程(或ThreadPool函数)开始时手动执行此操作。您也许可以将区域性名称(或仅区域性对象)存储在静态字段中，以避免访问DB，但仅此而已。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|350019|entityMap^0|15|A|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

This gets asked a lot. Basically, no there isn't, not for .NET 4.0. You have to do it manually at the start of each new thread (or <code>ThreadPool</code> function). You could perhaps store the culture name (or just the culture object) in a static field to save having to hit the DB, but that's about it.

In .NET 4.5, you can use the <a href="http://msdn.microsoft.com/en-us/library/system.globalization.cultureinfo.defaultthreadcurrentculture.aspx" rel="noreferrer"><code>CultureInfo.DefaultThreadCurrentCulture</code></a> 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 <code>CultureInfo</code> (<code>m_userDefaultCulture</code> in .NET 2.0 mscorlib, <code>s_userDefaultCulture</code> in .NET 4.0 mscorlib) that controls what <code>CurrentCulture</code> 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.

In the resource manager, there is an auto generated code that is as follows:

Actually you can set the default thread culture and UI culture, but only with Framework 4.5+

I put in this static constructor 

<pre><code>static MainWindow()
{
 CultureInfo culture = CultureInfo
 .CreateSpecificCulture(CultureInfo.CurrentCulture.Name);
 var dtf = culture.DateTimeFormat;
 dtf.ShortTimePattern = (string)Microsoft.Win32.Registry.GetValue(
 "HKEY_CURRENT_USER\\Control Panel\\International", "sShortTime", "hh:mm tt");
 CultureInfo.DefaultThreadCurrentUICulture = culture;
}
</code></pre>

and put a breakpoint in the Convert method of a ValueConverter to see what arrived at the other end. CultureInfo.CurrentUICulture ceased to be en-US and became instead en-AU complete with my little hack to make it respect regional settings for ShortTimePattern.

Hurrah, all is well in the world! Or not. The culture parameter passed to the Convert method is still en-US. Erm, WTF?! But it's a start. At least this way 

<ul>
<li>you can fix the UI culture once when your app loads</li>
<li>it's always accessible from <code>CultureInfo.CurrentUICulture</code></li>
<li><code>string.Format("{0}", DateTime.Now)</code> will use your customised regional settings</li>
</ul>

If you can't use version 4.5 of the framework then give up on setting CurrentUICulture as a static property of CultureInfo and set it as a static property of one of your own classes. This won't fix default behaviour of string.Format or make StringFormat work properly in bindings then walk your app's logical tree to recreate all the bindings in your app and set their converter culture.

Here is the solution for c# MVC:

<ol>
<li>First : Create a custom attribute and override method like this:

<pre><code>public class CultureAttribute : ActionFilterAttribute
{
 public override void OnActionExecuting(ActionExecutingContext filterContext)
 {
 // Retreive culture from GET
 string currentCulture = filterContext.HttpContext.Request.QueryString["culture"];

 // Also, you can retreive culture from Cookie like this :
 //string currentCulture = filterContext.HttpContext.Request.Cookies["cookie"].Value;

 // Set culture
 Thread.CurrentThread.CurrentCulture = new CultureInfo(currentCulture);
 Thread.CurrentThread.CurrentUICulture = CultureInfo.CreateSpecificCulture(currentCulture);
 }
}
</code></pre></li>
<li>Second : In App_Start, find FilterConfig.cs, add this attribute. (this works for WHOLE application)

<pre><code>public class FilterConfig
{
 public static void RegisterGlobalFilters(GlobalFilterCollection filters)
 {
 // Add custom attribute here
 filters.Add(new CultureAttribute());
 }
} 
</code></pre></li>
</ol>

That's it !

If you want to define culture for each controller/action in stead of whole application, you can use this attribute like this:

<pre><code>[Culture]
public class StudentsController : Controller
{
}
</code></pre>

Or:

<pre><code>[Culture]
public ActionResult Index()
{
 return View();
}
</code></pre>

Working solution to set CultureInfo for all threads and windows.
<ol>
<li>Open App.xaml file and add a new &quot;Startup&quot; attribute to assign startup event handler for the app:</li>
</ol>
<pre><code>&lt;Application ........
 Startup=&quot;Application_Startup&quot;
&gt;
</code></pre>
<ol start="2">
<li>Open App.xaml.cs file and add this code to created startup handler (Application_Startup in this case). The class App will look like this:</li>
</ol>
<pre><code> public partial class App : Application
 {
 private void Application_Startup(object sender, StartupEventArgs e)
 {
 CultureInfo cultureInfo = CultureInfo.GetCultureInfo(&quot;en-US&quot;);
 System.Globalization.CultureInfo.DefaultThreadCurrentCulture = cultureInfo;
 System.Globalization.CultureInfo.DefaultThreadCurrentUICulture = cultureInfo;
 Thread.CurrentThread.CurrentCulture = cultureInfo;
 Thread.CurrentThread.CurrentUICulture = cultureInfo;
 }
 }
</code></pre>

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 

<pre><code>CultureInfo ci = new CultureInfo(theCultureString);
Thread.CurrentThread.CurrentCulture = ci;
Thread.CurrentThread.CurrentUICulture = ci;
</code></pre>

But, of course, this gets "lost" when we want to do something in a new thread. Is there a way of setting that <code>CurrentCulture</code> and <code>CurrentUICulture</code> for the whole application? So that new threads also gets that culture? Or is it some event fired whenever a new thread is created that I can hook up to?

Is there a way of setting culture for a whole application? All current threads and new threads?
