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)

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)
}

您应该记录调用堆栈，而不仅仅是错误消息(IIRC，简单的异常。tostring()应该为您做这件事)。从那里，您可以确定异常的确切来源，并且通常可以推断出它是哪个异常。

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。

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;
