Merhaba,<\/p>\n
C# programlama dilinde bir s\u0131n\u0131ftan instance talep ederken “new<\/strong><\/em>” operat\u00f6r\u00fcn\u00fc kullanmaktay\u0131z. “new” operat\u00f6r\u00fc, talep edilecek olan nesnenin hangi s\u0131n\u0131ftan olaca\u011f\u0131n\u0131 kesin bilmek ister ve dolay\u0131s\u0131yla bu ihtiyac\u0131n\u0131 ilgili s\u0131n\u0131f\u0131n taraf\u0131m\u0131zdan belirtilerek giderilmesini istemektedir.<\/p>\n
\r\nnew MyClass();\r\n<\/pre>\nYukar\u0131daki kod blo\u011funu incelerseniz e\u011fer “new” operat\u00f6r\u00fc “MyClass” isimli s\u0131n\u0131f\u0131n bir instance’ini talep etmektedir. Ama burada dikkat edilmesi gereken husus “MyClass” s\u0131n\u0131f\u0131n\u0131n taraf\u0131m\u0131zca ilgili operat\u00f6re bildiriliyor olmas\u0131d\u0131r.<\/p>\n
E\u011fer ki, “new” operat\u00f6r\u00fc kullanmaks\u0131z\u0131n bir s\u0131n\u0131f\u0131n instance’\u0131n\u0131 olu\u015fturmak istiyorsan\u0131z sizlere sunaca\u011f\u0131m iki farkl\u0131 y\u00f6ntemi uygulayabilirsiniz.<\/p>\n
