使用.NET是否可以将自定义属性分配给内置对象,如FileSystemWatcher？

using System;
using System.IO;
using System.Reflection;

[AttributeUsage(AttributeTargets.All)]
public class CustomAttribute : Attribute
{
    public string Name { get; set; }
    public int Value { get; set; }
}

public class Program
{
    static void Main(string[] args)
    {
        FileSystemWatcher watcher = new FileSystemWatcher();
        watcher.Path = @"C:\";
        watcher.NotifyFilter = NotifyFilters.LastAccess | NotifyFilters.LastWrite
                                | NotifyFilters.FileName | NotifyFilters.DirectoryName;

        watcher.Filter = "*.txt";

        CustomAttribute customAttribute = new CustomAttribute
        {
            Name = "MyFileSystemWatcher",
            Value = 42
        };

        TypeDescriptor.AddAttributes(watcher, customAttribute);

        watcher.Changed += new FileSystemEventHandler(OnChanged);
        watcher.Created += new FileSystemEventHandler(OnChanged);
        watcher.Deleted += new FileSystemEventHandler(OnChanged);
        watcher.Renamed += new RenamedEventHandler(OnRenamed);

        watcher.EnableRaisingEvents = true;

        Console.WriteLine("Press \'q\' to quit.");
        while (Console.ReadKey().KeyChar != 'q') ;
    }

    private static void OnChanged(object source, FileSystemEventArgs e)
    {
        FileSystemWatcher watcher = source as FileSystemWatcher;
        CustomAttribute customAttribute = TypeDescriptor.GetAttributes(watcher)[typeof(CustomAttribute)] as CustomAttribute;

        Console.WriteLine($"{customAttribute.Name} detected a change: {e.FullPath}");
    }

    private static void OnRenamed(object source, RenamedEventArgs e)
    {
        FileSystemWatcher watcher = source as FileSystemWatcher;
        CustomAttribute customAttribute = TypeDescriptor.GetAttributes(watcher)[typeof(CustomAttribute)] as CustomAttribute;

        Console.WriteLine($"{customAttribute.Name} detected a rename: {e.OldFullPath} to {e.FullPath}");
    }
}
