1.生成配置文件

打开Enterprise Library Configuration(EntLibConfig.exe)，配置如下：



1.1 界面说明

①.Categories：日志分类，每个LogEntry至少关联一个分类，Logging Application Block允许添加多个分类，每个分类可添加多个Listeners；
②.Special Categories：特殊分类，不用和LogEntry关联，配置好就会生效。
·All Events：记录全部事件日志；
·Unprocessed Category：记录没有合适分类的日志，开启All Events时本分类失效；
·Logging Error & Warnings：记录Logging Application Block错误日志；
③.Logging Filters：过滤器；
④.Logging Target Listeners：日志位置保存，有Database、E-mail、Event Log、Flat File、Message Queuing、Rolling Flat File、System Diagnostics、WMI、XML；
⑤.Log Message Formatters：日志格式化，有Text Formatter和Binary Log Message Formatter ；

1.2 生成app.config文件

复制内容到剪贴板程序代码 程序代码
<configuration>
    <configSections>
        <section name="loggingConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.LoggingSettings, Microsoft.Practices.EnterpriseLibrary.Logging, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="true" />
    </configSections>
    <loggingConfiguration name="" tracingEnabled="true" defaultCategory="General">
        <listeners>
            <add name="Flat File Trace Listener" type="Microsoft.Practices.EnterpriseLibrary.Logging.TraceListeners.FlatFileTraceListener, Microsoft.Practices.EnterpriseLibrary.Logging, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
                listenerDataType="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.FlatFileTraceListenerData, Microsoft.Practices.EnterpriseLibrary.Logging, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
                fileName="c:\trace.log" formatter="Text Formatter" filter="All" />
            <add name="Email Trace Listener" type="Microsoft.Practices.EnterpriseLibrary.Logging.TraceListeners.EmailTraceListener, Microsoft.Practices.EnterpriseLibrary.Logging, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
                listenerDataType="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.EmailTraceListenerData, Microsoft.Practices.EnterpriseLibrary.Logging, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
                toAddress="270250392@qq.com" fromAddress="597421489@qq.com"
                subjectLineStarter="ServerError" smtpServer="smtp.qq.com"
                formatter="Text Formatter" authenticationMode="UserNameAndPassword"
                userName="597421489" password="666666" filter="Error" />
        </listeners>
        <formatters>
            <add type="Microsoft.Practices.EnterpriseLibrary.Logging.Formatters.TextFormatter, Microsoft.Practices.EnterpriseLibrary.Logging, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
                template="Timestamp: {timestamp}{newline}
Message: {message}{newline}"
                name="Text Formatter" />
        </formatters>
        <categorySources>
            <add switchValue="All" name="General">
                <listeners>
                    <add name="Flat File Trace Listener" />
                    <add name="Email Trace Listener" />
                </listeners>
            </add>
        </categorySources>
        <specialSources>
            <allEvents switchValue="All" name="All Events" />
            <notProcessed switchValue="All" name="Unprocessed Category" />
            <errors switchValue="All" name="Logging Errors & Warnings" />
        </specialSources>
    </loggingConfiguration>
</configuration>
