在winform项目里集成log4net日志控件

1、引用log4net.dll文件   备注：通过直接引用dll或使用nugit都可以

2、添加一个log4net.config文件，内容如下：

<?xml version="1.0" encoding="utf-8" ?>

  
    
"log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" />
  
  
    
    
    "Error">
      "ALL" />
      ref ref="ErrorAppender" />
    
    "InfoLog">
      "ALL" />
      ref ref="InfoAppender" />
    
    "ErrorAppender" type="log4net.Appender.RollingFileAppender,log4net" >
      "File" type="" value="Log/Error/" />
      "AppendToFile" value="true" />
      "RollingStyle" value="Date" />
      "DatePattern" value="yyyyMMdd" />
      "StaticLogFileName" value="false" />
      "log4net.Layout.PatternLayout,log4net">
        "ConversionPattern" value="%n[%d] %c %n%m%n%n" />
        "Header" value="-----------BEGIN-----------" />
        "Footer" value="------------END------------" />
      
    
    "InfoAppender" type="log4net.Appender.RollingFileAppender,log4net" >
      "File" type="" value="Log/Info/" />
      "AppendToFile" value="true" />
      "RollingStyle" value="Date" />
      "DatePattern" value="yyyyMMdd" />
      "StaticLogFileName" value="false" />
      "log4net.Layout.PatternLayout,log4net">
        "ConversionPattern" value="%n[%d] %c %n%m%n%n" />
        "Header" value="-----------BEGIN-----------" />
        "Footer" value="------------END------------" />
      
    
  

注意：在这个config文件上点右键属性，让它始终复制或较新复制

3、在Properties下的AssemblyInfo.cs文件时加一行：

[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", Watch = true)]

4、加一个Help类内容如下：

public class log4netHelper
    {
        /// 

        /// 普通日志
        /// 
        /// 日志内容
        public static void Info(string message)
        {
            log4net.ILog log = log4net.LogManager.GetLogger("InfoLog");
            if (log.IsInfoEnabled)
            {
                log.Info(message);
            }
            log = null;
        }
        /// 

        /// 错误日志
        /// 
        /// 错误日志
        public static void Error(string message)
        {
            log4net.ILog log = log4net.LogManager.GetLogger("Error");
            if (log.IsInfoEnabled)
            {
                log.Error(message);
            }
            log = null;
        }
    }

5、使用示例如下：

log4netHelper.Info("这是一条普通日志");
log4netHelper.Error("这是一条错误日志");
