在C#中,你可以使用FileSystemWatcher
类来监控文件系统的变化。要设置监控条件,你需要在创建FileSystemWatcher
实例时配置相应的属性。以下是一些常见的监控条件设置方法:
- 监控特定目录:
string path = @"C:\example_directory\"; FileSystemWatcher watcher = new FileSystemWatcher(path);
- 监控特定文件类型:
watcher.Filter = "*.txt"; // 监控所有.txt文件
- 监控文件名包含特定字符串:
watcher.Filter = "*example*.txt"; // 监控文件名包含"example"的所有.txt文件
- 监控文件创建事件:
watcher.NotifyFilter = NotifyFilters.CreationTime;
- 监控文件更改事件:
watcher.NotifyFilter = NotifyFilters.LastWrite | NotifyFilters.FileName;
- 监控文件删除事件:
watcher.NotifyFilter = NotifyFilters.LastWrite | NotifyFilters.FileName | NotifyFilters.Deletion;
- 监控文件重命名事件:
watcher.NotifyFilter = NotifyFilters.LastWrite | NotifyFilters.FileName | NotifyFilters.Renaming;
- 添加自定义事件处理程序:
watcher.Created += new FileSystemEventHandler(OnChanged); watcher.Changed += new FileSystemEventHandler(OnChanged); watcher.Deleted += new FileSystemEventHandler(OnChanged); watcher.Renamed += new RenamedEventHandler(OnRenamed); private static void OnChanged(object source, FileSystemEventArgs e) { // 处理文件更改事件 } private static void OnRenamed(object source, RenamedEventArgs e) { // 处理文件重命名事件 }
通过组合这些属性和事件处理程序,你可以根据需要设置监控条件。
