Question

我正在编写一个具有FileSystemWatcher的程序。我还想与FSW一起运行另外两种方法。但是我的其他方法无法执行，因为程序始终在FSW上。

本质上，我希望FileSystemWatcher继续运行并能够在我的程序中同时执行其他操作。

如何构造代码来实现这一目标？

当前，我的代码具有以下结构：

namespace MyApp
{
 class Program
 {
   static void Main(string[] args)
   {
     // call the FSW
     MyFileSystemWatcher(path);

     // call another method
     AnotherMethod1();  

     // call another method
     AnotherMethod2();
   }

   //----- file system watcher methods -----//

   private static void MyFileSystemWatcher(string path)
   {
     // code for the file system watcher
    FileSystemWatcher fileSystemWatcher = new FileSystemWatcher();
    fileSystemWatcher.Path = path;
    fileSystemWatcher.Created += FileSystemWatcher_Created;
    fileSystemWatcher.Renamed += FileSystemWatcher_Renamed;
    fileSystemWatcher.Deleted += FileSystemWatcher_Deleted;
    fileSystemWatcher.EnableRaisingEvents = true; 
   }

   private static void FileSystemWatcher_Created(object sender, FileSystemEventArgs e)
   {
        Console.WriteLine("File created: {0}", e.Name);
   }

   private static void FileSystemWatcher_Renamed(object sender, FileSystemEventArgs e)
   {
        Console.WriteLine("File renamed: {0}", e.Name);
   }

   private static void FileSystemWatcher_Deleted(object sender, FileSystemEventArgs e)
   {
        Console.WriteLine("File deleted: {0}", e.Name);
   }

   //----- end of file system watcher methods -----//

   //----- other methods in the program -----//

   public static void AnotherMethod1()
   {
    // code for Method1
   }

   private static void AnotherMethod2()
   {
    // code for Method2
   }

 }

}

谢谢。

使您的方法异步

然后

private static async Task MyFileSystemWatcher(string path)
{
    // code for the file system watcher
}

或者，如果您不想碰触您的方法（不理想），那么

 static void Main(string[] args)
 {
   // call the File System Watcher
   var task = MyFileSystemWatcher(path);

   // call another method
   AnotherMethod1();  

   // call another method
   AnotherMethod2();
 }

FileSystemWatcher与同时执行的其他方法
