问题描述

我正在写一个工具，将是检查工作站的运行状况通过网络，并且会根据发现问题的解决。我想创建一个日志文件中的应用程序是通过在每台机器上的任务/检查运行。我只是想获得一台机器上这个工作现在，但在时间它会一次过（螺纹出）来扫描100+机器。

I'm writing a tool that's going to be check the health of workstations across a network, and will fix according to the issues it finds. I want to create a log file as the app is running through its tasks / checks on each machine. I just want to get this working on a single machine for now, but in time it will be scanning 100+ machines in one go (Threaded out).

的 什么是创建日志文件的最好方法是什么？的

What is the best way to create a log file?

我想用名单，LT的;串> 建立在内存中的日志文件，然后输出到一旦它已经完成了文件

I was thinking of using a List<string> to build up the log file in memory and then output it to a file once it had finished.

我只是在想。可能有这样做的更好的办法？

I'm just thinking there may be a better way of doing this?

推荐答案

我不会使用第三方库，我会登录到一个XML文件。

I would not use third party libraries, I would log to an xml file.

这是那些记录到来自不同线程的XML文件中的代码示例：

This is a code sample that do logging to a xml file from different threads:

    private static readonly object Locker = new object();
    private static XmlDocument _doc = new XmlDocument();
    static void Main(string[] args)
    {
        if (File.Exists("logs.txt"))
            _doc.Load("logs.txt");
        else
        {
            var root = _doc.CreateElement("hosts");
            _doc.AppendChild(root);
        }
        for (int i = 0; i < 100; i++)
        {
            new Thread(new ThreadStart(DoSomeWork)).Start();
        }
    }
    static void DoSomeWork()
    {
        /*

         * Here you will build log messages

         */
        Log("192.168.1.15", "alive");
    }
    static void Log(string hostname, string state)
    {
        lock (Locker)
        {
            var el = (XmlElement)_doc.DocumentElement.AppendChild(_doc.CreateElement("host"));
            el.SetAttribute("Hostname", hostname);
            el.AppendChild(_doc.CreateElement("State")).InnerText = state;
            _doc.Save("logs.txt");
        }
    }
