调用代码1、
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using log4net;
[assembly: log4net.Config.XmlConfigurator(Watch = true)]
namespace yichangDEMO {
class LogHelper {
public static readonly ILog loginfo = log4net.LogManager.GetLogger("EventLogAppender"); //选择输出到windows事件中
public static void SetConfig() {
log4net.Config.XmlConfigurator.Configure();
}
public static void SetConfig(FileInfo configFile) {
log4net.Config.XmlConfigurator.Configure(configFile);
}
public static void WriteLog(string info) {
if (loginfo.IsInfoEnabled) {
loginfo.Info(info);
}
}
public static void WriteLog(string info, Exception se) {
if (loginfo.IsErrorEnabled) {
loginfo.Error(info, se);
}
}
}
}
调用代码2、
using System;
using System.Collections.Generic;
using System.Linq;
using System.Windows.Forms;
namespace yichangDEMO {
static class Program {
/// <summary>
/// 应用程序的主入口点。
/// </summary>
[STAThread]
static void Main() {
Application.ThreadException += new System.Threading.ThreadExceptionEventHandler(Application_ThreadException);
AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException);
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Form1());
}
static void Application_ThreadException(object sender, System.Threading.ThreadExceptionEventArgs e) {
Exception ex = e.Exception;
LogHelper.WriteLog("错误：", ex);
}
static void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e) {
Exception ex = (Exception)e.ExceptionObject;
LogHelper.WriteLog("错误：", ex);
}
}
}
这里同上偏随笔结合使用
已验证
