最近在一直的练习用VB。NET来书写程序。在VB中加入一个app.config文件,会有自动帮你生成一段关于Log output的配置,具体请看
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.diagnostics>
<sources>
<!-- This section defines the logging configuration for My.Application.Log -->
<source name="DefaultSource" switchName="DefaultSwitch">
<listeners>
<add name="FileLog"/>
<!-- Uncomment the below section to write to the Application Event Log -->
<!--<add name="EventLog"/>-->
</listeners>
</source>
</sources>
<switches>
<add name="DefaultSwitch" value="Information" />
</switches>
<sharedListeners>
<add name="FileLog"
type="Microsoft.VisualBasic.Logging.FileLogTraceListener, Microsoft.VisualBasic, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a, processorArchitecture=MSIL"
initializeData="FileLogWriter">
<!-- Uncomment the below section and replace APPLICATION_NAME with the name of your application to write to the Application Event Log -->
<!--<add name="EventLog" type="System.Diagnostics.EventLogTraceListener" initializeData="APPLICATION_NAME"/> -->
</sharedListeners>
</system.diagnostics>
</configuration>
这样配置完成后,运行后,日志会放在
C:\Users\username\Application Data\Company\Product\Version\AppName.log下。
但我感觉这样的目录太深了,不易于查找。 想换一个地方配置。 但利用VS2008的自动提示好像没有这样的设置项,这让我困惑了不少。但Google了一下发下还是可以做到的。 看来是VS2008里面的XML配置文件的Schema不是最新的(或是MS想隐藏些什么??)。
