这招对我很管用:

 //Exception Class Extensions
    public static class ExceptionExtensions
    {
        public static string EnMessage(this Exception ex)
        {
            CultureInfo oldCI = Thread.CurrentThread.CurrentCulture;
            string englishExceptionMessage = ex.Message;
            Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture("en-US");
            Thread.CurrentThread.CurrentUICulture = new CultureInfo("en-US");
            try
            {
                var objectType = Type.GetType(ex.GetType().FullName);
                var instantiatedObject = Activator.CreateInstance(objectType);                
                throw (Exception)instantiatedObject;
            }
            catch (Exception e)
            {
                englishExceptionMessage = e.Message;
            }
            Thread.CurrentThread.CurrentCulture = oldCI;
            Thread.CurrentThread.CurrentUICulture = oldCI;
            return englishExceptionMessage;
        }
    }

然后你可以通过调用新方法ex.EnMessage()来使用它;

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。

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(); }

基于Undercover1989答案，但考虑参数以及当消息由多个资源字符串组成时(如参数异常)。

public static string TranslateExceptionMessage(Exception exception, CultureInfo targetCulture)
{
    Assembly a = exception.GetType().Assembly;
    ResourceManager rm = new ResourceManager(a.GetName().Name, a);
    ResourceSet rsOriginal = rm.GetResourceSet(Thread.CurrentThread.CurrentUICulture, true, true);
    ResourceSet rsTranslated = rm.GetResourceSet(targetCulture, true, true);

    var result = exception.Message;

    foreach (DictionaryEntry item in rsOriginal)
    {
        if (!(item.Value is string message))
            continue;

        string translated = rsTranslated.GetString(item.Key.ToString(), false);

        if (!message.Contains("{"))
        {
            result = result.Replace(message, translated);
        }
        else
        {
            var pattern = $"{Regex.Escape(message)}";
            pattern = Regex.Replace(pattern, @"\\{([0-9]+)\}", "(?<group$1>.*)");

            var regex = new Regex(pattern);

            var replacePattern = translated;
            replacePattern = Regex.Replace(replacePattern, @"{([0-9]+)}", @"${group$1}");
            replacePattern = replacePattern.Replace("\\$", "$");

            result = regex.Replace(result, replacePattern);
        }
    }

    return result;
}

使用扩展方法覆盖捕获块中的异常消息，检查抛出的消息是否来自代码，如下所述。

    public static string GetEnglishMessageAndStackTrace(this Exception ex)
    {
        CultureInfo currentCulture = Thread.CurrentThread.CurrentUICulture;
        try
        {

            dynamic exceptionInstanceLocal = System.Activator.CreateInstance(ex.GetType());
            string str;
            Thread.CurrentThread.CurrentUICulture = new CultureInfo("en-US");

            if (ex.Message == exceptionInstanceLocal.Message)
            {
                dynamic exceptionInstanceENG = System.Activator.CreateInstance(ex.GetType());

                str = exceptionInstanceENG.ToString() + ex.StackTrace;

            }
            else
            {
                str = ex.ToString();
            }
            Thread.CurrentThread.CurrentUICulture = currentCulture;

            return str;

        }
        catch (Exception)
        {
            Thread.CurrentThread.CurrentUICulture = currentCulture;

            return ex.ToString();
        }

这可能是一个有争议的观点，但是与其将区域性设置为en-US，不如将其设置为Invariant。在“不变区域性”中，错误消息是英文的。

Thread.CurrentThread.CurrentCulture = CultureInfo.InvariantCulture;
Thread.CurrentThread.CurrentUICulture = CultureInfo.InvariantCulture;

它的优点是看起来没有偏见，特别是对于非美式英语地区。(也就是避免同事的冷嘲热讽)
