不是类的属性，是类似python中装饰器的东西，也类似java中的注解，vb.net把尖括号跟Attribute用了，泛型只能用其他的方式了

        <HttpPost()>
		<ValidateAntiForgeryToken()>
		Function Edit(<Bind(Include:="ID,Title,ReleaseDate,Genre,Price,Rating")> ByVal movie As Movie) As ActionResult
			If ModelState.IsValid Then
				db.Entry(movie).State = EntityState.Modified
				db.SaveChanges()
				Return RedirectToAction("Index")
			End If
			Return View(movie)
		End Function
