需要从ftp服务器下载最新文件 [英] Need to download latest file from ftp server

问题描述

我想从ftp服务器下载最后修改过的文件，或者我们可以说服务器上最新添加的文件。



请帮忙，因为我可以从服务器获取文件列表而不是新文件列表。



提前致谢。

FileSystemWatcher fileWatcherFTP = new FileSystemWatcher（）;



fileWatcherFTP.Path = directoryToWatch;



fileWatcherFTP.Filter =* .xml;



fileWatcherFTP .IncludeSubdirectories = true;



fileWatcherFTP.Created + = new FileSystemEventHandler（fileWatcherFTP_Changed）;



fileWatcherFTP。已更改+ = new FileSystemEventHandler（fileWatcherFTP_Changed）;



fileWatcherFTP.EnableRaisingEvents = true;







timerFTP = new System.Timers.Timer（60000）;



timerFTP.Enabled = true;



timerFTP.Elapsed + = new System.Timers.ElapsedEventHandler（timer_Elapsed）;



timerFTP.Start（）;







< br $>






void timer_Elapsed（object sender，System.Timers.ElapsedEventArgs e）



{



processFile（）;



}









private void processFile（）



{



试试



{



DirectoryInfo directoryInfo = new DirectoryInfo（directoryToWatch）;



FileInfo [] files = directoryInfo.GetFiles（）;



if（files.Count（）== 0）



{



//处理完所有文件后停止计时器



timerFTP.Stop（）;



T imerFTP.Enabled = false;



}



else



{



foreach（文件中的FileInfo fileInfo）



{





//处理文件





}



}



}



catch（Exception ex）{}



}





我做了未经测试的代码。您可以尝试此代码。

FileSystemWatcher fileWatcherFTP = new FileSystemWatcher();

fileWatcherFTP.Path = directoryToWatch;

fileWatcherFTP.Filter = "*.xml";

fileWatcherFTP.IncludeSubdirectories = true;

fileWatcherFTP.Created += new FileSystemEventHandler(fileWatcherFTP_Changed);

fileWatcherFTP.Changed += new FileSystemEventHandler(fileWatcherFTP_Changed);

fileWatcherFTP.EnableRaisingEvents = true;



timerFTP = new System.Timers.Timer(60000);

timerFTP.Enabled = true;

timerFTP.Elapsed += new System.Timers.ElapsedEventHandler(timer_Elapsed);

timerFTP.Start();







void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)

{

processFile ();

}




private void processFile()

{

try

{

DirectoryInfo directoryInfo = new DirectoryInfo(directoryToWatch);

FileInfo[] files = directoryInfo.GetFiles();

if (files.Count() == 0)

{

// Stop Timer when all files has been processed

timerFTP.Stop();

timerFTP.Enabled = false;

}

else

{

foreach (FileInfo fileInfo in files)

{


// process file


}

}

}

catch (Exception ex){}

}


I did not tested code. You can try this code.
