代码设定Log4net

在下面这个示例中，我将创建一个向控制台和"a.log"文件中写入日志的log

[csharp]
using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using log4net; 
using log4net.Appender; 
using log4net.Layout; 
using log4net.Repository.Hierarchy; 
 
namespace MyLog4Net 
{ 
    public class MyLog4Net 
    { 
        public static ILog GetMyLog(dynamic LogName) 
        { 
            ILog log = null; 
            if (LogName is string) 
            { 
                string name = (string)LogName; 
                log = log4net.LogManager.GetLogger(name); 
            } 
            else if (LogName is Type) 
            { 
                Type t = (Type)LogName; 
                log = log4net.LogManager.GetLogger(t); 
            } 
            else 
            { 
                throw new Exception("Parameter must be a string or Type value!"); 
            } 
            FileAppender fa = new FileAppender(); 
            fa.Name = "FileAppender1"; 
            fa.File = "a.log"; 
            fa.AppendToFile = true; 
            ConsoleAppender ca = new ConsoleAppender(); 
            ca.Name = "ConsoleAppender1"; 
            PatternLayout pl = new PatternLayout(); 
            pl.ConversionPattern = "[%d] - %p : %c => %m%n"; 
            pl.ActivateOptions(); 
            fa.Layout = pl; 
            fa.ActivateOptions(); 
            ca.Layout = pl; 
            ca.ActivateOptions(); 
            Hierarchy h = (Hierarchy)LogManager.GetRepository(); 
            h.Root.Level = h.LevelMap["DEBUG"]; 
            h.Root.AddAppender(fa); 
            h.Root.AddAppender(ca); 
            h.Configured = true; 
            return log; 
        } 
    } 
}
