config配置

1 <configuration>
2   <system.diagnostics>
3     <trace autoflush="true" indentsize="0">
4       <listeners>
5         <add name="LogListener" type="System.Diagnostics.TextWriterTraceListener" initializeData="..\log\LogConsoleApp.log"/>
6       </listeners>
7     </trace>
8   </system.diagnostics>
9 </configuration>

 

在运行程序目录上一层会生成一个Log\\LogConsoleApp.log文件
