Enterprise Library Logging 快速上手
这篇文章将演示花费最小的代价使用Microsoft’s Enterprise Library 4.1在你的应用程序中记录日志。下面是一些细节，第一次如何在代码logging Message:
下载安装Enterprise Library 4.1
让我们开始，创一个VS控制台程序名叫HelloWorldEntLibLogging,在项目中引用Ent. Lib. logging assembly，如图:
为应用程序配制Logging,增加一个App.config
在App.config文件上单击右键:
在弹出的菜单编辑器选择New | Logging Application Block
这时一个新的Logging Application Block 配制节点是这样的:
接着，打开App.config的XML内容是:
1: <?xml version="1.0" encoding="utf-8"?>
2: <configuration>
3: <configSections>
4: <section name="loggingConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.LoggingSettings, Microsoft.Practices.EnterpriseLibrary.Logging, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
5: <section name="dataConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings, Microsoft.Practices.EnterpriseLibrary.Data, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
6: </configSections>
7: <loggingConfiguration name="Logging Application Block" tracingEnabled="true"
8: defaultCategory="General" logWarningsWhenNoCategoriesMatch="true">
9: <listeners>
10: <add source="Enterprise Library Logging" formatter="Text Formatter"
11: log="Application" machineName="" listenerDataType="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.FormattedEventLogTraceListenerData, Microsoft.Practices.EnterpriseLibrary.Logging, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"

13: name="Formatted EventLog TraceListener" />
14: </listeners>
15: <formatters>
16: <add template="Timestamp: {timestamp}
