使用方法
Log m_log = Log.getInstance();
m_log.write("写日志测试");
m_log.write("写日志测试","debug");生成文件
日志记录格式
Log.cs 类
using System;
using System.Text;
using System.IO;
using System.Collections;
namespace Ank.Class
{
public class Log
{
private static Log m_log = null;
private string m_LogFilePath = "";
private string m_logPath = "";
private string m_logFilePrefix = "";
private Hashtable fosws = null;
private Log(string filePath, string logFilePrefix)
{
m_logPath = filePath;
m_logFilePrefix = logFilePrefix;
fosws = new Hashtable();
}
public static Log getInstance(string filePath=null, string logFilePrefix="log")
{
//
if (m_log == null)
{
if (filePath == null)
{
filePath = System.AppDomain.CurrentDomain.BaseDirectory==null?"c://": System.AppDomain.CurrentDomain.BaseDirectory;
}
m_log = new Log(filePath, logFilePrefix);
}
return m_log;
}
public void write(string logstr,string logtype="all")
{
string logTime = DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss");
write(logTime, logstr,logtype);
logstr = null;
}
public void write(string logTime, string logstr,string logtype="all")
{
logtype = logtype.ToLower();
try
{
//一小时写一个文件
string strNowY = DateTime.Now.Year.ToString();
string strNowM = DateTime.Now.Month.ToString();
string strNowD = DateTime.Now.Day.ToString();
string strNowH = DateTime.Now.Hour.ToString();
string fileName = m_logFilePrefix + "_" + strNowH + "0000_"+logtype+".log";
string filePath = m_logPath + "\\logs\\" + strNowY + "-" + strNowM + "-" + strNowD + "\\";
if (logTime != "")
{
logTime = "[" + logTime + "] ";
}
//LOG目录不存在，则创建
if (Directory.Exists(filePath) == false)
{
Directory.CreateDirectory(filePath);
}
m_LogFilePath = filePath + fileName;
//日志文件不存在，则创建
if (File.Exists(filePath + fileName) == false)
{
File.Create(filePath + fileName).Close();
}
StreamWriter fosw=null;
if (fosws.Contains(logtype))
{
fosw = (StreamWriter)fosws[logtype];
}
else
{
fosw = new StreamWriter(filePath + fileName, true, Encoding.UTF8);
fosws.Add(logtype,fosw);
};
//创建实例
if (fosw == null)
{
fosw = new StreamWriter(filePath + fileName, true, Encoding.UTF8);
fosws.Add(logtype, fosw);
}
//将内容写到log文件中
fosw.WriteLine(logTime + logstr);
//刷新，实时保存
fosw.Flush();
}
catch (Exception ex)
{
System.Diagnostics.Debug.Print("Log Error:" + ex.Message.ToString());
}
}
}
}
