企业库日志记录块不记录

标签： .net enterprise-library

我通过NuGet安装了Enterprise Library 6，然后使用Enterprise Library Configuration Application Block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类来进行日志记录：

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);

我已经遍历了代码，可以验证LoggerBlock.Write是否正在执行并且没有引发异常。但是，不会生成日志文件，并且事件日志也不会结束。

我想念什么？

编辑-这是App.config

我设法通过添加

来写入日志文件 
<listeners>
   <add name="Rolling Flat File Trace Listener" />
</listeners>

转到<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（您正在添加中）：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <configSections>
    <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->

           source="Enterprise Library Logging" formatter="Text Formatter"
           log="" machineName="." 
           traceOutputOptions="None" />

      <add name="Rolling Flat File Trace Listener" 
           type="Microsoft.Practices.EnterpriseLibrary.Logging.TraceListeners.RollingFlatFileTraceListener, Microsoft.Practices.EnterpriseLibrary.Logging, Version=6.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"

           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"
           template="Timestamp: {timestamp}{newline}&#xA;Message: {message}{newline}&#xA;Category: {category}{newline}&#xA;Priority: {priority}{newline}&#xA;EventId: {eventid}{newline}&#xA;Severity: {severity}{newline}"
           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" />
        </listeners>
      </errors>
    </specialSources>
  </loggingConfiguration>
  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6" />
  </startup>
  <entityFramework>
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.LocalDbConnectionFactory, EntityFramework">
      <parameters>

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

此后bin\Debug\MyLog.log成功创建：

时间戳：21/12/2018 11:29:32

消息：作业已执行...

类别：信息

优先级：2

EventId：1

严重性：信息

检查一下。
