在.Net中：在新线程上保持CurrentCulture的最佳方法？
在.NET4.0WPF项目中，我们需要在每个线程上保持与主线程相同的CurrentCulture 在给定条件下，我们可以使用如下代码初始化新线程的区域性：在.Net中：在新线程上保持CurrentCulture的最佳方法？,.net,wpf,multithreading,c#-4.0,culture,.net,Wpf,Multithreading,C# 4.0,Culture,在.NET4.0WPF项目中，我们需要在每个线程上保持与主线程相同的CurrentCulture 在给定条件下，我们可以使用如下代码初始化新线程的区域性： 将信息保存在变量（上下文）中 在新线程上，从保存的上下文初始化 Thread.CurrentThread.CurrentCulture = context.CurrentCulture; Thread.CurrentThread.CurrentUICulture = context.CurrentUICulture; 但在这个TPL、异
Thread.CurrentThread.CurrentCulture = context.CurrentCulture;
Thread.CurrentThread.CurrentUICulture = context.CurrentUICulture;
您知道我们应该初始化哪些设置、属性或配置以保持跟踪吗？没有好办法，请不惜一切代价避免。基本问题是区域性不是Thread.ExecutionContext的一部分，它不会从一个线程流向另一个线程。这是一个无法解决的问题，区域性是本机Windows线程的属性。它将始终初始化为控制面板区域和语言小程序中选择的系统区域性 对区域性进行临时线程本地更改是可以的，尝试将“进程”切换到另一个区域性会导致几个月的bug。字符串排序顺序是最糟糕的问题来源
编辑：此问题已在.NET 4.5中通过CultureInfo.DefaultThreadCurrentCulture和DefaultThreadCurrentUICulture属性修复
编辑：在.NET4.6中得到了真正的解决方案，文化现在从一个线程流向另一个线程。有关详细信息，请查看CultureInfo.CurrentCulture的MSDN文章。请注意，描述与行为不完全匹配，需要进行测试。我不明白为什么帕桑先生对此提出警告，同时说对文化进行“临时”“线程本地”更改是可以的。没有线程区域性是真正的线程本地的——正如我们所看到的，任何可以通过公共属性引用线程的东西都可以使用它。如果可以在短时间内改变它，那么为什么不能在更长时间内改变它呢？你在哪里越界，为什么 我也不真正理解OP的感觉，即“没有必要”编写代码来复制他想要复制的东西。您可能希望将此代码放在可以重用它的地方，但除此之外，我真的不认为代码有问题。在我的书中，它比我见过的任何lambda表达式都更直接、更美妙，而且它会很好地完成这项工作。至少我不喜欢写花哨的代码，因为它是花哨的 你可以这样做：
// Program.cs
static CultureInfo culture, uiCulture;
[STAThread]
static public void Main()
{
var t = Thread.CurrentThread;
culture = t.CurrentCulture;
uiCulture = t.CurrentUICulture;
}
static public Thread CreateThread()
{
return new Thread() { CurrentCulture = culture, CurrentUICulture = uiCulture }; }
}
顺便说一句，我突然意识到，尽管默认区域性来自Windows的“区域设置”，但它可能在.NET配置中被覆盖 如果这是一个ASP.NET应用程序，您应该使用
web.configglobalization（是我，还是微软使用全球化和本地化这两个词，相当混乱，可以互换？当我使用TPL创建任务时，我总是将文化传递给当前UI线程。请参见下面的示例代码
