Question

我正在尝试实施一个 Filewatcher ，它会为已创建或已更改（如果数据已更改）观看目录 FilesDir 文件。如果我只复制粘贴 FileDir 中的一个文件，它可以正常工作，但如果我复制粘贴多个文件，则只调用其中一个 File_Created 事件文件

public void SetUpFileWatcher()
{

    var sourcePath = ConfigurationManager.AppSettings["DirectoryPath"];
    var fileSystemWatcher = new FileSystemWatcher();

    fileSystemWatcher.IncludeSubdirectories = false;
    fileSystemWatcher.Filter = ConfigurationManager.AppSettings["FileType"];
    fileSystemWatcher.Path = sourcePath;
    fileSystemWatcher.EnableRaisingEvents = true;
    fileSystemWatcher.Created += FileMonitorWatcher_FileCreated;
    fileSystemWatcher.Changed += FileMonitorWatcher_FileChanged;


    Logger.Info("SetUpFileWatcher", "End of Setting Up File Watcher");
}


/// <summary>
/// Event called when a new file is created.
/// </summary>
/// <param name="sender">sender</param>
/// <param name="e">FileSystemEventArgs</param>
private void FileMonitorWatcher_FileCreated(object sender, FileSystemEventArgs e)
{
    Logger.Info("FileMonitorWatcher_FileCreated", "File created method started....");

    ((FileSystemWatcher)(sender)).EnableRaisingEvents = false;
    FileMonitorManager fileMonitorMgr = new FileMonitorManager();
    fileMonitorMgr.FileCreated(e.FullPath);
    ((FileSystemWatcher)(sender)).EnableRaisingEvents = true;
    Logger.Info("FileMonitorSystemWatcher_Created:End", "Create Function for File Watcher End at: " + DateTime.Now.ToString());
}

        /// <summary>
/// Event called when a file is changed.
/// </summary>
/// <param name="sender">sender</param>
/// <param name="e">FileSystemEventArgs</param>
private void FileMonitorWatcher_FileChanged(object sender, FileSystemEventArgs e)
{
    Logger.Info("FileMonitorWatcher_FileChanged", "Updated method started....");

    ((FileSystemWatcher)(sender)).EnableRaisingEvents = false;
    FileMonitorManager fileMonitorMgr = new FileMonitorManager();
    fileMonitorMgr.FileCreated(e.FullPath);
    ((FileSystemWatcher)(sender)).EnableRaisingEvents = true;
    Logger.Info("FileMonitorSystemWatcher_Changed:End", "Update Function for File Watcher End at: " + DateTime.Now.ToString());
}

帮助：

所以，我需要的FileWatcher是只有在创建新文件时才能观看目录并调用 File_Created 事件，而只有在文件中的某些数据时才会调用 File_Changed 事件改变了。

注意：

每当在监视目录中更改或创建文件时，都会为该文件调用 SomeTimeConsumingMethod（）方法来填充数据库中的数据。在我的情况下， SomeTimeConsumingMethod（）方法大约需要3-4分钟。

.NET：FileWatcher不适用于多个文件
