我使用Unity将一个新类实例化到控制器构造函数中,并将注入的类保存在控制器内的属性中.然后我想使用一个ActionFilter来查看注入的类是否具有我在其构造函数内验证的一些属性.那么有没有办法使用ActionFilter来验证注入类的属性？

解决方法
这样的事情？
- public class ValidateActionFilterAttribute : ActionFilterAttribute
- {
- public override void OnActionExecuting(ActionExecutingContext filterContext)
- {
- var yourController = filterContext.Controller as YourController;
- if (yourController == null)
- {
- throw new InvalidOperationException("It is not YourController !!!");
- }
- // It is YourController - validate here
- var yourProperty = yourController.YourProperty;
- // UPDATED ***************************
- // or test whether controller has property
- var property = filterContext.Controller.GetType().GetProperty("YourProperty");
- if(property == null)
- {
- throw new InvalidOperationException("There is no YourProperty !!!");
- }
- }
- }
