NET Timer 定时执行写日志任务解决方案

protected void Application_Start(object sender, EventArgs e)
{
System.Timers.Timer myTimer = new System.Timers.Timer(10000);
myTimer.Elapsed += new System.Timers.ElapsedEventHandler(OnTimedEvent);
myTimer.Interval = 10000;
myTimer.Enabled = true;

}

private static void OnTimedEvent(object source, System.Timers.ElapsedEventArgs e)
{

//指定日志文件的目录
string fileLogPath = AppDomain.CurrentDomain.BaseDirectory;
string fileLogName = "LogProjectTest_" + DateTime.Now.ToLongDateString() + "_log.txt";
/定义文件信息对象
FileInfo finfo = new FileInfo(fileLogPath + fileLogName);

//创建只写文件流
using (FileStream fs = finfo.OpenWrite())
{
//根据上面创建的文件流创建写数据流
StreamWriter strwriter = new StreamWriter(fs);
//设置写数据流的起始位置为文件流的末尾
strwriter.BaseStream.Seek(0, SeekOrigin.End);
//写入错误发生时间
strwriter.WriteLine("发生时间: " + DateTime.Now.ToString());
//写入日志内容并换行
strwriter.WriteLine("错误内容: " + message);
strwriter.WriteLine("错误内容: ");
//写入间隔符
strwriter.WriteLine("---------------------------------------------");
strwriter.WriteLine();
//清空缓冲区内容，并把缓冲区内容写入基础流
strwriter.Flush();
//关闭写数据流
strwriter.Close();
fs.Close();
}
}
