C# 文件监视程序事件触发_C#_Filesystemwatcher

C# 文件监视程序事件触发

C# 文件监视程序事件触发,c#,filesystemwatcher,C#,Filesystemwatcher,我有一个方法如下 public void Run() { // Create a new FileSystemWatcher and set its properties. FileSystemWatcher watcher = new FileSystemWatcher(); watcher.Path = "C:\\model_RCCMREC"; /* Watch for cha

我有一个方法如下

 public void Run()
        {
            // Create a new FileSystemWatcher and set its properties.
            FileSystemWatcher watcher = new FileSystemWatcher();
            watcher.Path = "C:\\model_RCCMREC";

            /* Watch for changes in LastAccess and LastWrite times, and
               the renaming of files or directories. */
            watcher.NotifyFilter = NotifyFilters.LastAccess | NotifyFilters.LastWrite | NotifyFilters.FileName | NotifyFilters.DirectoryName;
            //   watch wav files.
            watcher.Filter = "*.wav";

            // Add event handlers. 
            watcher.Created += new FileSystemEventHandler(OnChanged);

            // Begin watching.
            watcher.EnableRaisingEvents = true;
        }

而Onchanged事件处理程序

public  void OnChanged(object source, FileSystemEventArgs e)
        {

//I AM DOING SOMETHNG HERE

}

我希望在每次将新文件添加到文件夹时都运行Onchanged事件处理程序。为了模拟添加新文件，我做了一个测试方法

  public void test()
        { 

                File.Move(@"C:/TAKE_FORM_HERE_RCCM/59947874_59858856_03022013_074051_785_787_490_108.wav", @"C:/model_RCCMREC/59947874_59858856_03022013_074051_785_787_490_108.wav");

                 Run();

        }

但是，当我运行程序时，永远不会到达OnChanged事件处理程序

为什么会这样？或者我做错了什么？

试试这个

instead of using "created" Event use "Deleted" Event

watcher.Deleted += new FileSystemEventHandler(watcher_Deleted);



OnChange will occur if any change occurs in that particular folder , 
First set a path and put a text file inside it and run your exe or web app 
then rename any file inside the folder so that your event will come

您的问题是在初始化并启动FileSystemWatcher之前移动文件。要修复此调用，请先运行（）
