C# 简单日志帮助类LogHelper

调用：

LogHelper.Debug("");   

LogHelper.Info(""); 

LogHelper.Error("");

项目添加LogHelper类

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;

namespace AvoidMisplace
{
public class LogHelper
{
//在网站根目录下创建日志目录(bin文件夹→debug文件夹→logs文件夹)
public static string path = AppDomain.CurrentDomain.BaseDirectory + "logs";

//死锁
public static object loglock = new object();

public static void Debug(string content)
{
WriteLog("DEBUG", content);
}

public static void Info(string content)
{
WriteLog("INFO", content);
}

public static void Error(string content)
{
WriteLog("ERROR", content);
}

protected static void WriteLog(string type, string content)
{
lock (loglock)
{
if (!Directory.Exists(path))//如果日志目录不存在就创建
{
Directory.CreateDirectory(path);
}

string time = DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss:fff");//获取当前系统时间
string filename = path + "/" + DateTime.Now.ToString("yyyy-MM-dd") + ".log";//用日期对日志文件命名

//创建或打开日志文件，向日志文件末尾追加记录
StreamWriter mySw = File.AppendText(filename);

//向日志文件写入内容
string write_content = time + " " + type + ": " + content;
mySw.WriteLine(write_content);

//关闭日志文件
mySw.Close();
}
}
}
}
