如何获取英语版的Win32Exception

我有一个解决方案，所以我会把它上传到这里，以防有人需要它。如果有人有更好的解决方案，我会很高兴知道，所以请发表评论。

在Win32Exception的情况下，我们可以使用FormatMessage并将错误代码翻译成英语和默认语言，并将默认值替换为英语。如果我不替换英语，我会丢失参数。因此，如果替换失败，我将返回带有英语附加描述的异常。

这是我的完整解决方案：

{
    class Program
    {
        static void SetEnglishCulture()
        {
            CultureInfo ci = new CultureInfo("en-US");
            Thread.CurrentThread.CurrentCulture = ci;
            Thread.CurrentThread.CurrentUICulture = ci;
            Type type = typeof(CultureInfo);
            try
            {
                type.InvokeMember("s_userDefaultCulture", BindingFlags.SetField | BindingFlags.NonPublic | BindingFlags.Static, null, ci, new object[] { ci });
                type.InvokeMember("s_userDefaultUICulture", BindingFlags.SetField | BindingFlags.NonPublic | BindingFlags.Static, null, ci, new object[] { ci });
            } catch { }
            try
            {
                type.InvokeMember("m_userDefaultCulture", BindingFlags.SetField | BindingFlags.NonPublic | BindingFlags.Static, null, ci, new object[] { ci });
                type.InvokeMember("m_userDefaultUICulture", BindingFlags.SetField | BindingFlags.NonPublic | BindingFlags.Static, null, ci, new object[] { ci });
            } catch { }
        }
        [DllImport("kernel32.dll")]
        static extern uint FormatMessage(uint dwFlags, IntPtr lpSource, uint dwMessageId, uint dwLanguageId, StringBuilder lpBuffer, uint nSize, IntPtr Arguments);
        public static string Win32ExceptionInEnglish(Win32Exception ex)
        {
            const int nCapacity = 820; // max error length
            const uint FORMAT_MSG_FROM_SYS = 0x01000;
            const uint engLangID = (0x01<<10) | 0x09;
            const uint defLangID = 0x0;
            StringBuilder engSb = new StringBuilder(nCapacity);
            StringBuilder defSb = new StringBuilder(nCapacity);
            FormatMessage(FORMAT_MSG_FROM_SYS,IntPtr.Zero, (uint)ex.ErrorCode, defLangID, defSb, nCapacity, IntPtr.Zero);
            FormatMessage(FORMAT_MSG_FROM_SYS,IntPtr.Zero, (uint)ex.ErrorCode, engLangID, engSb, nCapacity, IntPtr.Zero);
            string sDefMsg = defSb.ToString().TrimEnd(' ','.',''r',''n');
            string sEngMsg = engSb.ToString().TrimEnd(' ','.',''r',''n');
            if(sDefMsg == sEngMsg) //message already in English (or no english on machine?)
            {
                //nothing left to do:
                return ex.Message;
            }
            else
            {
                string msg = ex.Message.Replace(sDefMsg,sEngMsg);
                if (msg == ex.Message)
                {
                    //replace didn't worked, can be message with arguments in the middle.
                    //I such as case print both: original and translated. to not lose the arguments.
                    return ex.Message + " (In English: " + sEngMsg + ")";
                }
                else 
                {
                    //successfuly replaced!
                    return msg;
                }
            }       
        }
        public static void Main(string[] args)
        {           
            SetEnglishCulture();
            try {
                // generate any exception ...
                const int notListenningPort = 2121;
                new TcpClient("localhost", notListenningPort);
            }
            catch(Win32Exception ex)//first try to cach win32 Exceptions
            {
                Console.WriteLine("W32 Exception: " + Win32ExceptionInEnglish(ex));
            }
            catch(Exception ex)//this fit to the rest .NET exceptions which affected by CultureInfo
            {
                Console.WriteLine("Exception: " +ex.Message);
            }   
        }
    }
}

SocketException是Win32Exception。像所有其他派生自Win32Exception的类一样，它使用Win32Exception.GetErrorMessage(int error)从Windows获取消息，使用内核32.DLL中的FormatMessage。

这样做，消息实际上来自Windows，而不是来自.NET。Windows将以Windows显示语言返回一条消息，AFAIK，您可以在.NET程序中对此执行任何操作。

您可能必须将打印错误到控制台的行包装在区域设置设置为英语的单独线程中，因为框架异常代码根据当前线程区域设置从其资源加载错误消息。这是我在代码中谈论的内容：

    static void Main(string[] args) {
    try {
        TcpClient c = new TcpClient("localhost", 1234);
    }
    catch (Exception ex) {
        // thread that logs exception message to console
        Thread logger = new Thread(new ParameterizedThreadStart(PrintException));
        logger.CurrentCulture = new System.Globalization.CultureInfo("en-US");
        logger.Start(ex);
    }

}
private static void PrintException(object ex) {
    Console.WriteLine("Error: " + ((Exception)ex).Message);
}
