我们通过将 Exception.Message 写入文件来记录系统中发生的任何异常。但是,它们是按照客户的文化编写的。土耳其语错误对我来说意义不大。
那么我们如何在不改变用户文化的情况下用英语记录任何错误消息呢?

这个问题可以部分解决。框架异常代码根据当前线程语言环境从其资源中加载错误消息。在某些例外情况下,这发生在访问 Message 属性时。
对于这些例外情况,您可以通过在记录消息时将线程区域设置短暂切换为 en-US 来获取消息的完整美国英语版本(事先保存原始用户区域设置并在之后立即恢复)。
在单独的线程上执行此操作会更好:这可以确保不会有任何副作用。例如:
try
{
System.IO.StreamReader sr=new System.IO.StreamReader(@"c:\does-not-exist");
}
catch(Exception ex)
{
Console.WriteLine(ex.ToString()); //Will display localized message
ExceptionLogger el = new ExceptionLogger(ex);
System.Threading.Thread t = new System.Threading.Thread(el.DoLog);
t.CurrentUICulture = new System.Globalization.CultureInfo("en-US");
t.Start();
}
ExceptionLogger 类看起来像这样:
class ExceptionLogger
{
Exception _ex;
public ExceptionLogger(Exception ex)
{
_ex = ex;
}
public void DoLog()
{
Console.WriteLine(_ex.ToString()); //Will display en-US message
}
}
但是,正如Joe在对此回复的早期版本的评论中正确指出的那样,在引发异常时,已经(部分)从语言资源中加载了一些消息。
例如,这适用于在引发 ArgumentNullException("foo") 异常时生成的消息的“参数不能为空”部分。在这些情况下,即使使用上述代码,消息仍将显示(部分)本地化。
除了使用不切实际的 hack,例如在具有 en-US 语言环境的线程上运行所有非 UI 代码之外,您似乎无能为力:.NET Framework 异常代码没有用于覆盖错误消息区域设置的工具。
您可以在unlocalize.com上搜索原始异常消息
也许是一个有争议的观点,但en-US
您可以将其设置为 ,而不是将文化设置为Invariant
。在Invariant
文化中,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,尤其是对于非美式英语语言环境。(又名避免同事的冷嘲热讽)
这是不需要任何编码的解决方案,即使对于加载得太早而我们无法通过代码更改的异常文本(例如,mscorlib 中的那些)也适用。
它可能并不总是适用于所有情况(这取决于您的设置,因为您需要能够在主 .exe 文件之外创建一个 .config 文件),但这对我有用。因此,只需创建一个包含以下行的app.config
in dev(或 a [myapp].exe.config
or web.config
in production),例如:
<configuration>
...
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="mscorlib.resources" publicKeyToken="b77a5c561934e089"
culture="fr" /> <!-- change this to your language -->
<bindingRedirect oldVersion="1.0.0.0-999.0.0.0" newVersion="999.0.0.0"/>
</dependentAssembly>
<dependentAssembly>
<assemblyIdentity name="System.Xml.resources" publicKeyToken="b77a5c561934e089"
culture="fr" /> <!-- change this to your language -->
<bindingRedirect oldVersion="1.0.0.0-999.0.0.0" newVersion="999.0.0.0"/>
</dependentAssembly>
<!-- add other assemblies and other languages here -->
</assemblyBinding>
</runtime>
...
</configuration>
这样做是告诉框架重定向mscorlib
' 资源 和System.Xml
' 资源的程序集绑定,对于 1 到 999 之间的版本,法语(文化设置为“ fr
”)到......不存在的程序集(任意999 版)。
因此,当 CLR 为这两个程序集(mscorlib 和 System.xml)寻找法语资源时,它不会找到它们并优雅地回退到英语。根据您的上下文和测试,您可能希望将其他程序集添加到这些重定向(包含本地化资源的程序集)。
当然,我认为微软不支持此功能,因此使用风险自负。好吧,如果您发现问题,您可以删除此配置并检查它是否无关。
Windows 需要安装您要使用的 UI 语言。它没有,它无法神奇地知道翻译的消息是什么。
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;
在 pt-PT、en-US 和 en-US 中生成消息。由于没有安装法语文化文件,它默认为 windows 默认(安装?)语言。
我知道这是一个老话题,但我认为我的解决方案可能与在网络搜索中偶然发现它的任何人都非常相关:
在异常记录器中,您可以记录 ex.GetType.ToString,这将保存异常类的名称。我希望类的名称应该独立于语言,因此总是用英语表示(例如“System.FileNotFoundException”),尽管目前我无法访问外语系统来测试主意。
如果您真的想要错误消息文本,您可以创建一个包含所有可能的异常类名称及其等效消息的字典,使用您喜欢的任何语言,但对于英语,我认为类名称就足够了。
CultureInfo oldCI = Thread.CurrentThread.CurrentCulture;
Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture ("en-US");
Thread.CurrentThread.CurrentUICulture=new CultureInfo("en-US");
try
{
System.IO.StreamReader sr=new System.IO.StreamReader(@"c:\does-not-exist");
}
catch(Exception ex)
{
Console.WriteLine(ex.ToString())
}
Thread.CurrentThread.CurrentCulture = oldCI;
Thread.CurrentThread.CurrentUICulture = oldCI;
没有变通方法。
谢:)
设置Thread.CurrentThread.CurrentUICulture
将用于本地化异常。如果您需要两种异常(一种为用户,一种为您),您可以使用以下函数来翻译异常消息。它在 .NET-Libraries 资源中搜索原始文本以获取资源键,然后返回翻译后的值。但是有一个弱点我还没有找到一个好的解决方案:消息中包含 {0} 的资源将不会被找到。如果有人有好的解决方案,我将不胜感激。
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)
}
.NET 框架分为两部分:
所有文本(例如异常消息、MessageBox 上的按钮标签等)在 .NET 框架本身中都是英文的。语言包具有本地化文本。
根据您的具体情况,一个解决方案是卸载语言包(即告诉客户这样做)。在这种情况下,例外文本将为英文。但是请注意,所有其他框架提供的文本也将是英文的(例如 MessageBox 上的按钮标签,ApplicationCommands 的键盘快捷键)。
基于 Undercover1989 答案,但考虑到参数以及消息何时由多个资源字符串组成(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;
}
我会想象其中一种方法:
异常只能由您阅读,即它们不是客户端功能,因此您可以使用硬连线的非本地化字符串,当您在土耳其语模式下运行时,这些字符串不会改变。
包括一个错误代码,例如0x00000001
每个错误,以便您可以轻松地在英文表格中查找它。
我有同样的情况,我在这里和其他地方找到的所有答案都没有帮助或不令人满意:
更改了 .net 异常的Thread.CurrentUICulture
语言,但它不会更改 .net ,它Win32Exception
以 Windows UI 本身的语言使用 Windows 资源。所以我从来没有设法Win32Exception
用英语而不是德语打印消息,甚至没有FormatMessage()
按照
How to get Win32Exception in English?
因此,我创建了自己的解决方案,它将不同语言的大部分现有异常消息存储在外部文件中。您不会以您想要的语言收到非常准确的信息,但您会收到该语言的信息,这比您当前获得的信息要多得多(这是您可能不理解的语言的信息)。
此类的静态功能可以在具有不同语言的 Windows 安装上执行:
CreateMessages()
创建特定于文化的文本
SaveMessagesToXML()
将它们保存到与创建或加载语言一样多的 XML 文件
LoadMessagesFromXML()
加载所有带有特定语言消息的 XML 文件
在使用不同语言的不同 Windows 安装上创建 XML 文件时,您很快就会拥有所需的所有语言。
当您安装了多个 MUI 语言包时,也许您可以在 1 个 Windows 上创建不同语言的文本,但我还没有测试过。
经VS2008测试,即可使用。欢迎提出意见和建议!

string englishExceptionMessage = ex.Message;
Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture("en-US");
Thread.CurrentThread.CurrentUICulture = new CultureInfo("en-US");
try

catch (Exception e)
{
englishExceptionMessage = e.Message;
}
Thread.CurrentThread.CurrentCulture = oldCI;
Thread.CurrentThread.CurrentUICulture = oldCI;
return englishExceptionMessage;
}
}
然后,您可以通过调用新方法 ex.EnMessage(); 来使用它。
您应该记录调用堆栈,而不仅仅是错误消息(IIRC,简单的 exception.ToString() 应该为您执行此操作)。从那里,您可以准确地确定异常的来源,并且通常可以推断出它是哪个异常。
使用扩展方法覆盖 catch 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();
}
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(除了在通常客户端的 UICulture 中显示它)。
为此,以下代码
然后最后将当前的 UICulture 改回更早的 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();
}
英语异常信息
try
{
......
}
catch (Exception ex)
{
throw new UserFriendlyException(L("ExceptionmessagesinEnglish"));
}
然后转到 Localization 文件夹并将其放在 projectName.xml 中并添加
<text name="ExceptionmessagesinEnglish">Exception Message in English</text>
