【CSharp】简单的文件日志纪录类

利用FileLogTraceListener记录日志，需要添加Microsoft.VisualBasic引用


	?using System;
	using System.IO;
	using Microsoft.VisualBasic.Logging;

	namespace MyLog
	{
	 enum LogLevel
	 {
	 Error = 0,
	 Warning,
	 Notice,
	 Info,
	 Debug
	 }

	 static class FileLog
	 {
	 static FileLogTraceListener logtl = new FileLogTraceListener();
	 static string fileName;
	 public static LogLevel logLevel = LogLevel.Info;

	 static FileLog()
	 {
	 logtl.Location = LogFileLocation.Custom;
	 logtl.CustomLocation = AppDomain.CurrentDomain.BaseDirectory + @"..\log";
	 logtl.MaxFileSize = 5 * 1024 * 1024;
	 logtl.DiskSpaceExhaustedBehavior = DiskSpaceExhaustedOption.ThrowException;
	 logtl.AutoFlush = true;
	 fileName = logtl.FullLogFileName;
	 }

	 public static void DebugLog(string format, params object[] args)
	 {
	 Log(LogLevel.Debug, format, args);
	 }

	 public static void ErrLog(string format, params object[] args)
	 {
	 Log(LogLevel.Error, format, args);
	 }

	 public static void Log(LogLevel level, string format, params object[] args)
	 {
	 if (level > logLevel)
	 {
	 return;
	 }

	 string prefix = string.Format("{0} [{1,-7}]", DateTime.Now.ToString(), level.ToString());
	 string msg;
	 if (args.Length > 0)
	 {
	 msg = string.Format(format, args);
	 }
	 else
	 {
	 msg = format;
	 }
	 string res = string.Format("{0} {1}", prefix, msg);
	
	 try
	 {
	 logtl.WriteLine(res);
	 }
	 catch
	 {
	 try
	 {
	 File.Delete(fileName + ".old");
	 File.Move(fileName, fileName + ".old");
	 logtl.WriteLine(res);
	 }
	 catch { }
	 }
	 }
	 }
	}

试试其它关键字

　日志　　文件日志　

同语言下

可能有用的
