Use log4net in winform

First download log4net (nonsense ...)
1. Add log4net reference
2. Create a configuration file under the winform program. The default configuration file is app. config. The changes are as follows:
3-20 rows are newly added

Configuration File
1 <? XML version = "1.0" encoding = "UTF-8"?>
2 <configuration>
3 <configsections>
4 <section name = "log4net" type = "log4net. config. log4netconfigurationsectionhandler, log4net"/>
5 </configsections>
6
7 <log4net>
8 <root>
9 <level value = "all"/>
10 <appender-ref = "logfileappender"/>
11 </root>
12
13 <appender name = "logfileappender" type = "log4net. appender. fileappender">
14 <Param name = "file" value = "log-file.txt"/>
15 <Param name = "appendtofile" value = "true"/>
16 <layout type = "log4net. layout. patternlayout">
17 <Param name = "conversionpattern" value = "% d [% T] %-5 p % C [% x] & lt; % x {auth} & gt; % N-% m % N "/>
18 </layout>
19 </appender>
20 </log4net>
21 </configuration>

3. After adding, add the following to assemblyinfo. CS:

[Assembly: log4net. config. domconfigurator (configfileextension = "Config", watch = true)]

4. Then add logs in the program using the following method (I wrote them directly in the main function for testing): 1 static void main ()
2 {
3 log4net. ilog log = log4net. logmanager. getlogger ("test ");
4 log. debug ("test ");
5}

5. When the producer runs, the log file log-file.txt is generated under the DEBUG directory of the target project. The content is as follows: 1 14:02:38, 890 [11] Debug test [(null)] <(null)>
2-Test

In this way, you can use log4net to record logs in the program. Of course, this is just a helloworld-level example that allows log4net to run. For specific usage instructions, see the official log4net documentation. There are also some Chinese introduction, such as http://www.cnblogs.com/dragon/archive/2005/03/24/124254.html (my essay is to refer to this article and the author's reply to write a little)
Enjoy log4net!
