C# 日志框架的添加

C#记录日志主要是用Log4Net和微软自己的

复杂一点的还可以实现自动化Log日志 教程

---

首先是第二种方式

1.需要添加以下几个DLL  下载

• Microsoft.Practices.EnterpriseLibrary.Logging.dll
• Microsoft.Practices.ObjectBuilder2.dll
• Microsoft.Practices.EnterpriseLibrary.Common.dll

2.Web.config 的configuration节点中添加以下内容

  <configSections>

    <section name="loggingConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.LoggingSettings, Microsoft.Practices.EnterpriseLibrary.Logging, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />

    <section name="dataConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings, Microsoft.Practices.EnterpriseLibrary.Data, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />

  </configSections>



  <loggingConfiguration name="Logging Application Block" tracingEnabled="true" defaultCategory="General" logWarningsWhenNoCategoriesMatch="true">

    <listeners>

      <add fileName="Log\Service.log" footer="----------------------------------------" formatter="Text Formatter" rollFileExistsBehavior="Increment" rollInterval="Day" rollSizeKB="10240" timeStampPattern="yyy-MM-dd" listenerDataType="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.RollingFlatFileTraceListenerData, Microsoft.Practices.EnterpriseLibrary.Logging, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" traceOutputOptions="None" filter="All" type="Microsoft.Practices.EnterpriseLibrary.Logging.TraceListeners.RollingFlatFileTraceListener, Microsoft.Practices.EnterpriseLibrary.Logging, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" name="Rolling Flat File Trace Listener" />

    </listeners>

    <formatters>

      <add template="时间: {timestamp} 类型: {severity} 标题: {title} 内容: {message}" type="Microsoft.Practices.EnterpriseLibrary.Logging.Formatters.TextFormatter, Microsoft.Practices.EnterpriseLibrary.Logging, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" name="Text Formatter" />

    </formatters>

    <categorySources>

      <add switchValue="All" name="Debug" />

      <add switchValue="All" name="General">

        <listeners>

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

        </listeners>

      </add>

    </categorySources>

    <specialSources>

      <allEvents switchValue="All" name="All Events" />

      <notProcessed switchValue="All" name="Unprocessed Category" />

      <errors switchValue="All" name="Logging Errors &amp; Warnings" />

    </specialSources>

  </loggingConfiguration>

注意：configSections节点一定要在loggingConfiguration节点的上面

3.调用

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Diagnostics;

using System.Reflection;

using System.Configuration;

using Microsoft.Practices.EnterpriseLibrary.Logging;

using System.Collections;



public sealed class LogWriter

{

    public LogWriter()

    {

    }



    /// <summary>

    /// 输出错误日志

    /// </summary>

    /// <param name="exception"></param>

    public static void WriteError(Exception exception, string title)

    {

        LogEntry logEntity = new LogEntry();

        logEntity.Title = title;

        logEntity.TimeStamp = DateTime.Now;

        logEntity.Message = exception.ToString();

        logEntity.Severity = TraceEventType.Error;

        Logger.Write(logEntity);

    }

}
