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 !!!");
}
}
}
