企业库日志记录块不记录

Question

我通过 NuGet 安装了 Enterprise Library 6，然后使用 Enterprise Library 配置应用程序块控制台将日志记录设置为滚动平面文件和事件日志。

然后我创建了一个静态 class 来进行日志记录：

public static class LoggerBlock {
    public static void Write(string message, string category, int priority, int eventID, TraceEventType severity)
    {
        LogWriter logWriter = new LogWriterFactory().Create();
        Logger.SetLogWriter(logWriter, false);
        logWriter.Write(message, category, priority, eventID, severity);
        logWriter.Dispose();
    }
}

我这样称呼它：

LoggerBlock.Write("Job executed...", "Information", 2, 1, System.Diagnostics.TraceEventType.Information);

我已经单步执行了代码并且可以验证 LoggerBlock.Write 正在执行并且没有抛出异常。但是，没有生成日志文件，事件日志中也没有任何结果。

我错过了什么？

编辑 - 这是 App.config

Answer 1

我设法通过添加

来写入日志文件

<listeners>
   <add name="Rolling Flat File Trace Listener" />
</listeners>

前往 <allEvents switchValue="All" name="All Events"> 部分。

这是我的代码（控制台应用程序）：

using Microsoft.Practices.EnterpriseLibrary.Logging;
using System;
using System.Diagnostics;

namespace ELogging
{
    internal static class LoggerBlock
    {
        private static readonly LogWriter LogWriter;

        static LoggerBlock()
        {
            LogWriter = new LogWriterFactory().Create();
            Logger.SetLogWriter(LogWriter, false);
        }

        public static void Write(string message, string category, int priority, int eventId, TraceEventType severity) => LogWriter.Write(message, category, priority, eventId, severity);
    }

    internal class Program
    {
        private static void Main(string[] args)
        {
            LoggerBlock.Write("Job executed...", "Information", 2, 1, TraceEventType.Information);
            Console.ReadKey();
        }
    }
}

和我的App.config（你的添加）：

<?xml version="1.0" encoding="utf-8"?>

           log="" machineName="."

      <add name="Rolling Flat File Trace Listener"

           fileName="MyLog.log" formatter="Text Formatter"
           rollInterval="None" />
    </listeners>
    <formatters>
      <add type="Microsoft.Practices.EnterpriseLibrary.Logging.Formatters.TextFormatter, Microsoft.Practices.EnterpriseLibrary.Logging, Version=6.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"

           name="Text Formatter" />
    </formatters>
    <categorySources>
      <add switchValue="All" name="General">
        <listeners>
          <add name="Event Log Listener" />
        </listeners>
      </add>
    </categorySources>
    <specialSources>
      <allEvents switchValue="All" name="All Events">
        <listeners>
          <add name="Rolling Flat File Trace Listener" />
        </listeners>
      </allEvents>
      <notProcessed switchValue="All" name="Unprocessed Category" />
      <errors switchValue="All" name="Logging Errors &amp; Warnings">
        <listeners>
          <add name="Event Log Listener" />

      <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />

  </entityFramework>
</configuration>

在此之后 bin\Debug\MyLog.log 已成功创建：

时间戳：21/12/201811:29:32

消息：作业已执行...

类别：信息

优先级：2

事件编号：1

严重性：信息

检查一下。
