跟踪侦听器未写入跟踪信息 [英] Trace listener not writing trace information

问题描述

public sealed class Logger
    {
        private static TraceSource myTraceSource;

        private Logger()
        {

        }

        public static TraceSource Create()
        {
            if (myTraceSource == null)
                return myTraceSource = new TraceSource("myTraceSource");
            else
                return myTraceSource;
        }


        public static void WriteInfo(string message)
        {
            myTraceSource.TraceEvent(TraceEventType.Information, 0, message);
            myTraceSource.Flush();
        }

        public static void WriteError(Exception ex)
        {
            myTraceSource.TraceEvent(TraceEventType.Error, 1, ex.Message);
            myTraceSource.Flush();

        }

        public static void WriteError(string message)
        {
            myTraceSource.TraceEvent(TraceEventType.Error, 1, message);
            myTraceSource.Flush();
        }

        public static void WriteWarning(string message)
        {
            myTraceSource.TraceEvent(TraceEventType.Warning, 2, message);
            myTraceSource.Flush();
        }

        public static void AddListener(TraceListener listener)
        {
            myTraceSource.Listeners.Add(listener);
        }

        public static void Close()
        {
            if (myTraceSource != null)
            {
                myTraceSource.Flush();
                myTraceSource.Close();
            }
        }<code></code>

    }
}

这是我如何初始化源并添加侦听器的方式

Here is how i am initializing the source it and adding the listener

Logger.Create();
TextWriterTraceListener myTextListener = new TextWriterTraceListener(LogCompletePath);
Logger.AddListener(myTextListener);
Logger.WriteError("error");

推荐答案

在另一个论坛中获得答案.我忘了提到源代码级别"，默认情况下它设置为关闭"

Got the answer in another forum. I forgot to mention Source Level and by default it is set to off

return myTraceSource = new TraceSource("myTraceSource", SourceLevels.All);
