Log4net简单配置使用

1项目中引用程序集log4net.dll

2往项目Properties 中的 AssemlyInfo.cs添加一行

[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", Watch = true)] ，即指明log4net的配置文件

3添加日志类

 1 /// <summary>
 2 /// 日志记录文件
 3 /// </summary>
 4 public class Logger
 5 {
 6 private static log4net.ILog log = null;
 7 private static log4net.ILog logDB = null;
 8 private static object lockHelper = new object();
 9 public static log4net.ILog Log
10 {
11 get {
12 if (log == null)
13 {
14 lock (lockHelper)
15 {
16 log = log4net.LogManager.GetLogger("MyLogger");
17 }
18 }
19 return log;
20 }
21 }
22 public static log4net.ILog LogDB
23 {
24 get
25 {
26 if (logDB == null)
27 {
28 lock (lockHelper)
29 {
30 logDB = log4net.LogManager.GetLogger("ADONetAppender");
31 }
32 }
33 return logDB;
34 }
35 }
36 
37 public static void LogInfo(string msg)
38 {
39 Log.Info(msg);
40 }
41 }

4外层项目添加配置文件log4net.config,设置文件属性

”log4Net配置文件属性药设置成 始终复制“

 1 <?xml version="1.0" encoding="utf-8" ?>
 2 <configuration>
 3   <log4net>
 4     <root>
 5       <!--<level value="ALL" />

41     </logger>
42   </log4net>
43 </configuration>
