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,它们是在客户的文化中写成的。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?

您可以在unlocalize.com
搜索原始例外消息答案 1 :(得分:62)
这个问题可以部分解决。 Framework异常代码根据当前线程区域设置从其资源加载错误消息。在某些例外情况下,这会在访问Message属性时发生。
对于这些例外情况,您可以通过在记录时将线程区域设置简单地切换到en-US来获取完整的美国英语版本的消息(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甚至更好:这可确保不会产生任何副作用。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:
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在对此回复的早期修订版的评论中正确指出的那样,在抛出异常时已经(部分)从语言资源加载了一些消息。
这适用于抛出ArgumentNullException(“foo”)异常时生成的消息的'parameter not not null'部分。在这些情况下,即使使用上述代码,消息仍会显示(部分)本地化。
除了使用不切实际的黑客攻击之外,例如在开始使用en-US语言环境的线程上运行所有非UI代码,似乎没有太多可以做的事情:.NET Framework异常代码没有覆盖错误消息区域设置的工具。
答案 2 :(得分:37)
也许有争议的一点,但您可以将文化设置为en-US
,而不是将文化设置为Invariant
。在Invariant
文化中,错误消息是英文。
Thread.CurrentThread.CurrentCulture = CultureInfo.InvariantCulture;
Thread.CurrentThread.CurrentUICulture = CultureInfo.InvariantCulture;
它具有不偏见的优点,特别是对于非美国英语区域。 (a.k.a.避免同事的讽刺言论)
答案 3 :(得分:10)
Windows需要安装要使用的UI语言。它没有,它无法神奇地知道翻译的消息是什么。
在en-US windows 7 ultimate中,安装了pt-PT,代码如下:
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,因此默认为Windows默认(已安装?)语言。
答案 4 :(得分:9)
这里的解决方案不需要任何编码,甚至可以用于过早加载的异常文本,以便我们能够通过代码更改(例如,mscorlib中的那些)。
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文件旁边创建.config文件)但这对我有用。因此,只需在开发中创建一个app.config
,(或生产中的[myapp].exe.config
或web.config
),其中包含以下行,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)被设置为&#34; fr
&#34;)到...不存在的程序集(任意版本999)。
因此,当CLR为这两个程序集(mscorlib和System.xml)查找法语资源时,它将无法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,我不认为这是微软支持的,所以使用风险自负。好吧,如果您发现问题,可以删除此配置并检查它是否无关。
答案 5 :(得分:4)
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独立于语言,因此总是用英语表示(例如&#34; System.FileNotFoundException&#34;),但目前我无法访问外语系统来测试这个想法。
如果您真的想要错误消息文本,您可以使用您喜欢的任何语言创建所有可能的异常类名称及其等效消息的字典,但对于英语,我认为类名称是完全足够的。

设置Thread.CurrentThread.CurrentUICulture
将用于本地化例外。如果您需要两种异常(一种针对用户,一种针对您),您可以使用以下函数来翻译异常消息。它在.NET-Library资源中搜索orignal文本以获取资源键,然后返回已翻译的值。但是有一个弱点我还没有找到一个好的解决方案:资源中包含{0}的消息将无法找到。如果有人有一个好的解决方案,我将不胜感激。
public static string TranslateExceptionMessage(Exception E, CultureInfo targetCulture)
{
try
{
Assembly a = E.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);
foreach (DictionaryEntry item in rsOriginal)
if (item.Value.ToString() == E.Message.ToString())
return rsTranslated.GetString(item.Key.ToString(), false); // success
}
catch { }
return E.Message; // failed (error or cause it's not intelligent enough to locale '{0}'-patterns
}
答案 8 :(得分:3)
.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,解决方案是卸载语言包(即告诉客户端这样做)。在这种情况下,例外文本将使用英语。但请注意,所有其他框架提供的文本也将是英文(例如MessageBox上的按钮标签,ApplicationCommands的键盘快捷方式)。
答案 9 :(得分:2)
我会想象其中一种方法:
1)您只能读取异常,即它们不是客户端功能,因此您可以使用在土耳其模式下运行时不会更改的硬连线非本地化字符串。
2)包括错误代码,例如。每个错误都有0X00000001,以便您可以在英文表格中轻松查看。

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者不满意:

C# - Getting Exception messages in English when the application is in another language?
How to change Visual Studio exception message language to English while debugging
How to handle translation of exception message?
How to completely avoid localized .NET exception messages
Thread.CurrentUICulture
更改了.net异常的语言,但它不适用于Win32Exception
,它使用Windows用户界面本身语言的Windows资源。因此,我从未设法用英语而不是德语打印Win32Exception
的消息,即使使用FormatMessage()
也没有如上所述
How to get Win32Exception in English?
因此,我创建了自己的解决方案,该解决方案将外部文件中不同语言的大多数现有异常消息存储起来。你不会用你想要的语言得到非常准确的信息,但你会收到一种语言,这比你目前得到的更多(这是一条你可能不太了解的语言的信息)。
此类的静态函数可以在具有不同语言的Windows安装上执行:
CreateMessages()
创建特定文化的文本
SaveMessagesToXML()
将它们保存到创建或加载语言的XML文件中
LoadMessagesFromXML()
使用特定于语言的消息加载所有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 当你安装了多个MUI语言包时,也许你可以在1个Windows上创建不同语言的文本,但我还没有测试过。
使用VS2008测试,随时可以使用。欢迎提出意见和建议!

为此目的,以下代码
然后最终将当前的UICulture更改回早期的UICulture。

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();
