c# - 企业库日志记录和文本格式化程序模板 token 。如何？

Question

我正在尝试让我的日志记录组件按照我的意愿工作。当我看到这篇文章时 How to configure Enterpise Library 6.0 logging to database?

我发现格式化程序:

<formatters>
  <add type="Microsoft.Practices.EnterpriseLibrary.Logging.Formatters.TextFormatter, Microsoft.Practices.EnterpriseLibrary.Logging, Version=6.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" template="Application: {property(ApplicationName)}{newline}&#xA;Guid: {property(HandlingInstanceId)}{newline}&#xA;Timestamp: {timestamp}{newline}&#xA;Message: {message}{newline}&#xA;Exception type: {property(ExceptionType)}{newline}&#xA;Category: {category}{newline}&#xA;Severity: {severity}{newline}&#xA;Machine: {localMachine}{newline}&#xA;App Domain: {localAppDomain}{newline}&#xA;ProcessId: {localProcessId}{newline}&#xA;Process Name: {localProcessName}{newline}&#xA;Stack trace: {property(StackTrace)}{newline}&#xA;File: {property(FileName)}{newline}&#xA;Line: {property(LineNumber)}{newline}"
  name="Text Formatter" />
</formatters>

包含我不知道如何使用的“Text Formatter Template Tokens”？

"Stack trace: {property(StackTrace)}{newline}&#xA"

目前我的日志记录类如下所示:

    public class Logging : Microsoft.Practices.EnterpriseLibrary.Logging.LogEntry
{     
    /// <summary>
    /// Logs an error message.
    /// </summary>
    /// <param name="Message"></param>
    /// <param name="processEvent"></param>
    public void LogToFile(string message, System.Diagnostics.TraceEventType severity)
    {
        try
        {
            LogWriterFactory logWriterFactory = new LogWriterFactory();
            LogWriter logWriter = logWriterFactory.Create();
            LogEntry logEntry = new LogEntry();
            LogSource logsource = new LogSource("ESRAlarmStatistik");

            logEntry.Message = message.ToString();
            //logEntry.EventId = Convert.ToInt32(processEvent);
            logEntry.Priority = 2;
            logEntry.Severity = severity;
            logEntry.TimeStamp = System.DateTime.Now;

            logWriter.Write(logEntry);

            //Unlocks the logfile so that it's possible to delete it.
            logWriter.Dispose();
        }
        catch (LoggingException ex)
        {
            throw ex;
        }
    }
}

我想记录有关异常的更多信息，而不仅仅是消息。例如。文本格式化程序模板 token 建议的堆栈跟踪是可能的。

但是，我不知道该怎么做？有没有人对如何实现对上述文本格式化程序的支持有任何经验？

此时日志输出如下所示:

----------------------------------------
Application: <Error: property ApplicationName not found>

Guid: <Error: property HandlingInstanceId not found>

亲切的问候!

附言我正在使用 Enterprise Library 6.0

Answer 1

它看起来像你的

LogEntry logEntry = new LogEntry();

不包含格式化程序请求的属性:

logEntry.StackTrace = "missing Informaton in your LogToFile Method"

所以我认为，你必须扩展它。
