Question

我有以下配置：

<?xml version="1.0" encoding="utf-8" ?>
<log4net>
  <appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%date{ABSOLUTE} 
    [%thread] %level %logger - %message%newline"/>
    </layout>
  </appender>

  <appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
    <file value="Logs\Log.txt" />
    <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
    <appendToFile value="true" />
    <rollingStyle value="Date" />
    <maximumFileSize value="5MB" />
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%date{ABSOLUTE} 
    [%thread] %level %logger - %message%newline" />
    </layout>
    <encoding value="utf-8" />
  </appender>

  <logger name="TraceLogger" additivity="false">
    <level value="INFO" />
    <appender-ref ref="RollingFileAppender"/>
    <appender-ref ref="ConsoleAppender" />
  </logger>
</log4net>

我在XmlConfigurator上运行了配置：

static class ProgramEntry
{
    static void Main(string[] args)
    {
        log4net.Config.XmlConfigurator.Configure();
        ...

我的web.config有：

<configuration>
  <configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" requirePermission="false" />    
  </configSections>

...

<log4net configSource="Config\log4net.config" />

...




<system.diagnostics>
    <trace autoflush="true" indentsize="0">
      <listeners>
        <add name="Log4NetTraceListener" type="BLAH.Log4netTraceListener, BLAH" />
      </listeners>
    </trace>
  </system.diagnostics>

我有一个Trace侦听器实现：

public class Log4netTraceListener : System.Diagnostics.TraceListener
{
    private readonly ILog log;

    public Log4netTraceListener()
    {
        log = LogManager.GetLogger("TraceLogger");

        // disable logging to trace write if logging fails, or else we'll end up in a deadlock.
        log4net.Util.LogLog.EmitInternalMessages = false;
    }

    private string level = "Info";

    public override void Write(string message)
    {
        if (message.Contains("Error:"))
        {
            level = "Error";
        }
        else if (message.Contains("Warning:"))
        {
            level = "Warning";
        }
        else if (message.Contains("Information:"))
        {
            level = "Info";
        }
        else
        {
            if (log != null)
            {
                LogMessage(message);
            }
        }
    }

    public override void WriteLine(string message)
    {
        if (log != null)
        {
            LogMessage(message);
        }

        // reset the level
        level = "Info";
    }

    private void LogMessage(string message)
    {
        if (level == "Info")
        {
            log.Info(message);
        }

        if (level == "Error")
        {
            log.Error(message);
        }

        if (level == "Warning")
        {
            log.Warn(message);
        }
    }
}

跟踪侦听器运行，似乎找到“TraceLogger”，但其appenders集合为空。

我可能做错了什么？真正的问题是

修改

发现错误：

log4net：ERROR无法解析配置文件。是个指定为： System.Configuration.ConfigurationErrorsException：无法打开 configSource文件'Config \ log4net.config'。（C：\ Users \ awdawd \ Documents \ Visual Studio 2015年\项目\ BLAH \ BLAH \ BLAH \ BIN \调试\ DataFactoryPreparationManager.exe.Config 第36行

我的app.config位于根目录中，我的Config文件夹位于此目录下

确保通过＆＃39;复制到输出目录＆＃39;将log4net.config复制到bin\Debug\Config。 Visual Studio中的文件属性。在解决方案资源管理器中右键单击该文件，然后选择“属性”。

在Logger for Log4net中，Appenders列表为空
