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();
}
}
}
}
