在另一篇SO文章中可以看到更详细的答案。

关于。net Core和以上，线程文档。CurrentUICulture推荐使用CultureInfo。属性检索和设置当前区域性。

CultureInfo.CurrentUICulture = CultureInfo.InvariantCulture;

在一个相关的GitHub问题上，Tarek Mahmoud Sayed建议使用CultureInfo。defaultthreadcurrentuicculture以确保稍后创建的其他线程也将获得相同的区域性:

CultureInfo.DefaultThreadCurrentUICulture = CultureInfo.InvariantCulture;

后者只在。net Framework 4.5(和。net Core 1.0)之后才可用。

我知道这是一个古老的话题，但我认为我的解决方案可能与任何在网络搜索中偶然发现它的人非常相关:

在异常记录器中，您可以记录ex.GetType。ToString，它将保存异常类的名称。我希望类的名称应该是独立于语言的，因此总是用英语表示(例如。“system . filenotfoundexception”)，尽管目前我还没有一个外语系统来测试这个想法。

如果您真的想要错误消息文本，您可以创建一个字典，其中包含所有可能的异常类名称及其等效消息，无论您喜欢哪种语言，但对于英语，我认为类名已经足够了。

Setting Thread.CurrentThread.CurrentUICulture will be used to localize the exceptions. If you need two kinds of exceptions (one for the user, one for you) you can use the following function to translate the exception-message. It's searching in the .NET-Libraries resources for the original text to get the resource-key and then return the translated value. But there's one weakness I didn't find a good solution yet: Messages, that contains {0} in resources will not be found. If anyone has a good solution I would be grateful.

public static string TranslateExceptionMessage(Exception ex, CultureInfo targetCulture)
{
    try
    {
        Assembly assembly = ex.GetType().Assembly;
        ResourceManager resourceManager = new ResourceManager(assembly.GetName().Name, assembly);
        ResourceSet originalResources = resourceManager.GetResourceSet(Thread.CurrentThread.CurrentUICulture, createIfNotExists: true, tryParents: true);
        ResourceSet targetResources = resourceManager.GetResourceSet(targetCulture, createIfNotExists: true, tryParents: true);
        foreach (DictionaryEntry originalResource in originalResources)
            if (originalResource.Value.ToString().Equals(ex.Message.ToString(), StringComparison.Ordinal))
                return targetResources.GetString(originalResource.Key.ToString(), ignoreCase: false); // success

    }
    catch { }
    return ex.Message; // failed (error or cause it's not smart enough to find texts with '{0}'-patterns)
}

出于日志记录的目的，某些应用程序可能需要获取英文异常消息(除了在通常客户机的UICulture中显示它之外)。

为此，使用以下代码

changes the current UICulture recreates the thrown Exception object using "GetType()" & "Activator.CreateInstance(t)" displays the new Exception object's Message in the new UICuture and then finally changes the current UICulture back to earlier UICulture. try { int[] a = { 3, 6 }; Console.WriteLine(a[3]); //Throws index out of bounds exception System.IO.StreamReader sr = new System.IO.StreamReader(@"c:\does-not-exist"); // throws file not found exception throw new System.IO.IOException(); } catch (Exception ex) { Console.WriteLine(ex.Message); Type t = ex.GetType(); CultureInfo CurrentUICulture = System.Threading.Thread.CurrentThread.CurrentUICulture; System.Threading.Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo("en-US"); object o = Activator.CreateInstance(t); System.Threading.Thread.CurrentThread.CurrentUICulture = CurrentUICulture; // Changing the UICulture back to earlier culture Console.WriteLine(((Exception)o).Message.ToString()); Console.ReadLine(); }

Windows需要安装你想要使用的UI语言。如果没有，它没有办法神奇地知道翻译后的信息是什么。

在安装了pt-PT的en-US windows 7 ultimate中，以下代码:

Thread.CurrentThread.CurrentUICulture = CultureInfo.GetCultureInfo("pt-PT");
string msg1 = new DirectoryNotFoundException().Message;

Thread.CurrentThread.CurrentUICulture = CultureInfo.GetCultureInfo("en-US");
string msg2 = new FileNotFoundException().Message;

Thread.CurrentThread.CurrentUICulture = CultureInfo.GetCultureInfo("fr-FR");
string msg3 = new FileNotFoundException().Message;

生成pt-PT, en-US和en-US格式的消息。由于没有安装法语文化文件，它默认为windows默认(已安装?)语言。
