\u015eimdi ise, 2.Metod ismindeki Create overload\u0131n\u0131 inceleyelim.Daha detayl\u0131 incelemek i\u00e7in bu metodu a\u015fa\u011f\u0131ya tek olarak al\u0131yorum.<\/p>\n

Kullan\u0131c\u0131 gerekli verileri girdikten sonra, Create butonuna t\u0131klayacak, bizim olu\u015fturup g\u00f6nderdi\u011fimiz Ogrenci nesnesini alanlar\u0131 doldurulmu\u015f bir \u015fekilde 2.Metod ismindeki Create metoduna geri g\u00f6nderecektir.[HttpPost] attribute u bu metodun post i\u015flemi sonucunda devreye girece\u011fini g\u00f6steriyor.<\/p>\n
Gelen nesneyi, 2.Metod isimli Create overload\u0131 FormCollection tipinden olan “collection” ismindeki parametre yakalayacakt\u0131r.Mant\u0131ken biz kullanc\u0131ya bir Ogrenci tipinden bir nesne g\u00f6ndermi\u015ftik.Eee haliyle kullan\u0131c\u0131da bize o nesneyi, verileri yerle\u015ftirilmi\u015f bir \u015fekilde geri g\u00f6nderdi.Yani, piyasada bir tane Ogrenci nesnesi mevcutken, Create FormCollection tipinden parametreyle bu nesneyi yakalayaca\u011f\u0131ma, direkt Ogrenci tipinden parametreyle yakalar\u0131m daha iyi.<\/p>\n
