如何获得在C＃中当前的区域设置？ [英] How to get current regional settings in C#?

问题描述

通常情况下，你可以通过编写像

Normally you can get it by writing something like

的CultureInfo的CurrentCulture = Thread.CurrentThread.CurrentCulture;

不过这样一来，你只能得到的CultureInfo这是目前应用程序的启动配置，如果设置已经改变之后将不会更新。

But this way you can only get CultureInfo which was configured at the moment application was launched and will not update if the setting have been changed afterwards.

那么，如何让当前的CultureInfo控制面板中的配置 - >区域和语言设置

So, how to get CultureInfo currently configured in Control Panel -> Regional and Language Settings?

推荐答案

由于@Christian提出的 ClearCachedData 是使用的方法。但根据MSDN：

As @Christian proposed ClearCachedData is the method to use. But according to MSDN:

该ClearCachedData方法不
  刷新的信息
  Thread.CurrentCulture属性
  现有线程

The ClearCachedData method does not refresh the information in the Thread.CurrentCulture property for existing threads

所以，你需要先调用的函数，然后开始一个新的线程。在这个新的线程可以使用的CurrentCulture获得文化的新鲜值。

So you will need to first call the function and then start a new thread. In this new thread you can use the CurrentCulture to obtain the fresh values of the culture.

class Program
{
    private class State
    {
        public CultureInfo Result { get; set; }
    }

    static void Main(string[] args)
    {
        Thread.CurrentThread.CurrentCulture.ClearCachedData();
        var thread = new Thread(
            s => ((State)s).Result = Thread.CurrentThread.CurrentCulture);
        var state = new State();
        thread.Start(state);
        thread.Join();
        var culture = state.Result;
        // Do something with the culture
    }

}

请注意，如果您还需要重置的CurrentUICulture，您需要单独做

Note, that if you also need to reset CurrentUICulture, you should do it separately

Thread.CurrentThread.CurrentUICulture.ClearCachedData()
