Bu yaz\u0131mda C# 5.0 ile gelen Caller Information \u00f6zelli\u011fine de\u011finece\u011fiz.Caller Information(\u00c7a\u011f\u0131ran \u00d6zellikleri) nedir k\u0131saca \u00f6zetlemek gerekirse, c\u00fcmlenin T\u00fcrk\u00e7e telafuzu bir nevi ip ucu vermektedir.Bir metodun nereden(hangi metod taraf\u0131ndan) \u00e7a\u011fr\u0131ld\u0131\u011f\u0131 bilgisine ula\u015fabilmemizi sa\u011flayan yap\u0131d\u0131r.Bu yap\u0131n\u0131n kullan\u0131m alanlar\u0131na de\u011findikten sonra programatik yap\u0131s\u0131n\u0131 inceleyelim.

Herhangi bir i\u015flem i\u00e7in olu\u015fturdu\u011fumuz bir fonksiyonu projemizin \u00e7o\u011fu yerinde \u00e7a\u011f\u0131r\u0131p kulland\u0131\u011f\u0131m\u0131z\u0131 farz edelim.Proje derlenip \u00e7al\u0131\u015ft\u0131\u011f\u0131 a\u015famada fornksiyonumuz i\u00e7erisinde bir hata verirse e\u011fer, nerede hata ald\u0131\u011f\u0131m\u0131z\u0131 zor kestirebiliriz.\u00c7\u00fcnk\u00fc \u00e7o\u011fu yerde bu fonksiyonu kulland\u0131\u011f\u0131m\u0131zdan dolay\u0131 hangi kod dosyas\u0131nda oldu\u011funu, hangi metod da ya da hangi sat\u0131rda oldu\u011funu bulabilmek i\u00e7in debug modunda \u00e7al\u0131\u015ft\u0131r\u0131p sat\u0131r sat\u0131r incelemeniz gerekmektedir.<\/p>\n

\u0130\u015fte bu gibi durumlar\u0131n \u00fcstesinden rahat bir \u015fekilde gelebilmek i\u00e7in Caller Informations ile fonksiyonumuzu tam olarak sat\u0131r numaras\u0131ndan tutun dosya yoluna kadar, nereden(hangi metoddan) \u00e7a\u011fr\u0131ld\u0131\u011f\u0131 bilsine ula\u015fabiliriz.<\/p>\n

\u015eimdi programatik olarak konuyu irdelememize devam edelim.<\/p>\n

Caller Info \u00f6z niteli\u011fine eklenmi\u015f 3 farkl\u0131 \u00f6zellik bulunmaktad\u0131r.Bu \u00f6zellikler; “CallerMemberName”, “CallerFilePath” ve “CallerLineNumber” \u00f6zellikleridir.<\/p>\n

Bu \u00f6zellikleri a\u00e7\u0131klayal\u0131m.<\/p>\n

CallerMemberName :<\/span> Bu \u00f6zelli\u011fin kullan\u0131ld\u0131\u011f\u0131 metod, hangi metod taraf\u0131ndan \u00e7a\u011fr\u0131l\u0131yorsa, o metodun ismini d\u00f6ner.
\nCallerFilePath :<\/span> Bu \u00f6zelli\u011fin kullan\u0131ld\u0131\u011f\u0131 metod, hangi metod taraf\u0131ndan \u00e7a\u011fr\u0131l\u0131yorsa, o metodun dosya yolunu g\u00f6nderir.
\nCallerLineNumber :<\/span> Bu \u00f6zelli\u011fin kullan\u0131ld\u0131\u011f\u0131 metodun, sat\u0131r numaras\u0131n\u0131 d\u00f6ner.<\/p>\n

Bu \u00fc\u00e7 \u00f6zelli\u011fi kullanarak, fonksiyonumuzun parametrelerine Attribute olarak tan\u0131mlamam\u0131z bu bilgilere eri\u015fmemiz i\u00e7in yeterlidir.Bu \u00f6zellikler, “System.Runtime.CompilerServices” k\u00fct\u00fcphanesi alt\u0131nda bulunmaktad\u0131r.<\/p>\n

\r\n        static void Main(string[] args)\r\n        {\r\n            OrnekMetod("\u00d6rnek \u00e7al\u0131\u015fan metod.");\r\n        }\r\n        static void OrnekMetod(string GelenDeger, [CallerMemberName]string MetodAdi = "", [CallerFilePath]string MetodYolu = "", [CallerLineNumber]int MetodSatirYolu = 0)\r\n        {\r\n            Console.WriteLine("\u00c7a\u011f\u0131ran Metodun Ad\u0131 : " + MetodAdi);\r\n            Console.WriteLine("\u00c7a\u011f\u0131ran Metodun Yolu : " + MetodYolu);\r\n            Console.WriteLine("\u00c7a\u011f\u0131ran Metodun Sat\u0131r Numaras\u0131 : " + MetodSatirYolu);\r\n            Console.WriteLine("Gelen De\u011ferimiz : " + GelenDeger);\r\n            Console.Read();\r\n        }\r\n<\/pre>\n
Yukar\u0131daki kodu derleyip \u00e7al\u0131\u015ft\u0131rd\u0131ktan sonra a\u015fa\u011f\u0131daki gibi \u00e7\u0131kt\u0131 al\u0131yoruz.

Son olarak dikkat etmemiz gereken bir husus var.Olu\u015fturdu\u011fumuz metod, basit bir \u015fekilde bir property(\u00f6zellik) ya da bir metod i\u00e7inde kullan\u0131l\u0131yorsa, o metodlar\u0131n isimleri neyse g\u00f6nderecektir.E\u011fer Constructor(Yap\u0131c\u0131 metod) gibi \u00f6zel metodlar i\u00e7erisinde \u00e7a\u011f\u0131r\u0131l\u0131rsa, bu sefer “CallerMemberName” \u00f6zellikleri “.ctor” ismini geri d\u00f6necektir.<\/p>\n
