\nMimaride haz\u0131r olarak gelen filtrelerde \u00f6ncelik s\u0131ras\u0131 ‘Authorization Filter<\/em>‘, ‘Action Filter<\/em>‘, ‘Result Filter<\/em>‘ ve ‘Exception Filter<\/em>‘ \u015feklindedir.
\nTabi bu durumda ayn\u0131 tipe sahip Attribute’lar yani filtreler \u00f6ncelik s\u0131ras\u0131na g\u00f6re \u00e7al\u0131\u015fmaktad\u0131r.Bununla ilgili bir \u00f6rnek yapal\u0131m.<\/p>\n

\r\n    [AttributeUsage(AttributeTargets.Method, AllowMultiple = true)]\r\n    public class Karsilayici : ActionFilterAttribute, IActionFilter\r\n    {\r\n        public string KarsilayiciMetin { get; set; }\r\n        public override void OnActionExecuting(ActionExecutingContext filterContext)\r\n        {\r\n            filterContext.HttpContext.Response.Write("<h4>" + KarsilayiciMetin + "<\/h4>");\r\n        }\r\n    }\r\n<\/pre>\nYukar\u0131daki gibi bir Attribute’umuz oldu\u011funu varsayal\u0131m.Bu Attribute’u incelersek e\u011fer, ‘AttributeUsage’ isimli Attribute ile i\u015faretlenmi\u015f bir yap\u0131ya sahip.’AttributeTargets.Method’ \u00f6zelli\u011fiyle bu Attribute’un bir metod \u00fczerinde \u00e7al\u0131\u015faca\u011f\u0131n\u0131 belirtiyoruz.’AllowMultiple = true’ \u00f6zelli\u011fiyle ise bir metodu bu Attribute ile birden fazla i\u015faretleyebiliyoruz.<\/p>\n
\u015eimdi herhangi bir Action metodu bu Attribute ile i\u015faretleyelim.<\/p>\n\r\n        [Karsilayici(KarsilayiciMetin = "Merhaba")]\r\n        [Karsilayici(KarsilayiciMetin = "Ho\u015f geldiniz.")]\r\n        public ActionResult Index()\r\n        {\r\n            return View();\r\n        }\r\n<\/pre>\nYukar\u0131daki kod blo\u011funu incelerseniz e\u011fer, bir Attribute s\u0131n\u0131f\u0131 i\u00e7inde bulunan Property’e parantezler e\u015fli\u011finde ula\u015fabiliyor ve gerekli de\u011feri set edebiliyoruz.
\nE\u011fer projeyi bu \u015fekilde derleyip \u00e7al\u0131\u015ft\u0131r\u0131rsak a\u015fa\u011f\u0131daki g\u00f6r\u00fcnt\u00fc ekrana gelecektir.

\nG\u00f6rd\u00fc\u011f\u00fcn\u00fcz gibi ayn\u0131 tipe sahip filtreler \u00f6ncelik s\u0131ras\u0131na g\u00f6re devreye girmi\u015f bulunmakta.E\u011fer ki, filtrelerin \u00e7al\u0131\u015fma s\u0131ras\u0131n\u0131 de\u011fi\u015ftirmek istiyorsan\u0131z “Order” parametresini kullanman\u0131z yeterli olacakt\u0131r.<\/p>\n
\u00d6rnek olarak a\u015fa\u011f\u0131daki kod blo\u011funu inceleyiniz.<\/p>\n
\r\n        [Karsilayici(KarsilayiciMetin = "Merhaba", Order = 2)]\r\n        [Karsilayici(KarsilayiciMetin = "Ho\u015f geldiniz.", Order = 1)]\r\n        public ActionResult Index()\r\n        {\r\n            return View();\r\n        }\r\n<\/pre>\nBu kod blo\u011funda ise, filtrelerimin “Order” parametrelerine verilen de\u011fer s\u0131ralamas\u0131 neticesine g\u00f6re \u00e7al\u0131\u015fmas\u0131 ger\u00e7ekle\u015ftirilecek ve ekrana a\u015fa\u011f\u0131daki gibi yans\u0131yacakt\u0131r.
