服务程序监控配置是否更改

服务程序（Service1.cs）

protected override void OnStart(string[] args)

{

//调试用

//System.Threading.Thread.Sleep(15000);

log4net.Config.XmlConfigurator.ConfigureAndWatch( new System.IO.FileInfo(Sxmobi.FileHelper.GetMapPath("")+ "log4net.config"));

_timer = new System.Timers.Timer(_interval);

_timer.Elapsed += new ElapsedEventHandler(_timer_Elapsed);

_timer.Start();

}

void _timer_Elapsed(object sender, ElapsedEventArgs e)

{

//要做的事情

this._timer.Enabled = false;

try

{

while (true)

{

Sxmobi.LogHelper.Info(this.GetType().ToString(), "VP2抓取程序开始", null);

TaskProc tp = new TaskProc();

tp.LoadTask();

WaitHandle.WaitAll(tp.waitHandles);//配置文件更改后此语句会执行

}

}

catch (Exception ex)

{

Sxmobi.LogHelper.Error(this.GetType().ToString() ,ex.Message,ex);

Sxmobi.LogHelper.Info(this.GetType().ToString(), "VP2抓取程序已停止", null);

}

}

监控程序（TaskProc.cs）

public WaitHandle[] waitHandles;

public TaskProc()

{

}

public void LoadTask()

{

ListParser lp = new ListParser();

ListParser.iCurrent++;//结束上一个线程

new Thread(new ThreadStart(lp.RunBat)).Start();

JianKong();

}

void JianKong()

{

this.waitHandles = new WaitHandle[] { new AutoResetEvent(false) };

AutoResetEvent are = (AutoResetEvent)this.waitHandles[0];

do

{

Thread.Sleep(10000);

}

while (!SiteConfig.ConfigIsUpdate);//配置文件更改后执行下面语句

are.Set();

}

主程序（ListParser.cs）

class ListParser

{

public static int iCurrent = 0;

public ListParser() { }

public void RunBat()

{

int ic = iCurrent;

while (ic==iCurrent)//是否是同一线程

{

RutAllFiles(SiteConfig.BatFileRoot);

Thread.Sleep(1000);

}

}

private void RutAllFiles(string fileDirectory)

{

DirectoryInfo diSource = new DirectoryInfo(fileDirectory);

FileSystemInfo[] fsi = diSource.GetFileSystemInfos();

FileInfo fi;

try

{

for (int i = 0; i < fsi.Length; i++)

{

//不是目录，查看文件属性；是目录，继续遍历。

if (Directory.Exists(fsi[i].FullName) == false)

{

fi = new FileInfo(fsi[i].FullName);

//判断文件类型，进行相应的后继操作。

if (fi.Extension == ".bat")

{

try

{

Process p = new Process();

ProcessStartInfo psi = new ProcessStartInfo(fi.FullName);

p.StartInfo = psi;

p.Start();

p.WaitForExit(30000);

File.Delete(fi.FullName);

Thread.Sleep(500);

}

catch (Exception ex)

{

Sxmobi.LogHelper.Error(this.GetType().ToString(), ex.Message, ex);

}

}

}

else

{

RutAllFiles(fsi[i].FullName);

}

}

}

catch (Exception ex)

{

Sxmobi.LogHelper.Error(this.GetType().ToString(), ex.Message, ex);

}

}

读取配置程序（SiteConfig.cs）

private static string xmlPath = Sxmobi.FileHelper.GetMapPath("~") + "\\Config\\Site.config";

static XmlDocument xmlDoc = Sxmobi.XmlHelper.GetXmlDoc(xmlPath);

private static DateTime LastestXmlModefyTime = Utility.getFileModifyTime(xmlPath);

public static bool ConfigIsUpdate

{

get

{

try

{

if ((Utility.getFileModifyTime(xmlPath) != DateTime.MinValue) && (LastestXmlModefyTime != Utility.getFileModifyTime(xmlPath)))

{

LastestXmlModefyTime = Utility.getFileModifyTime(xmlPath);

xmlDoc = Sxmobi.XmlHelper.GetXmlDoc(xmlPath);//重新读取config

return true;

}

return false;

}

catch

{

return false;

}

}

}

public static string BatFileRoot

{

get

{

return Sxmobi.XmlHelper.GetNodeValue(xmlDoc, "/Site/BatFileRoot");

}

}
