Merhaba,<\/p>\n

Kod yazarken class tiplerini yahut metod, property veya field isimlerini string olarak ifade etmemiz gereken noktalar olabilir. \u0130\u015fte b\u00f6yle durumlar i\u00e7in geli\u015ftirilmi\u015f olan C# 6.0 ile gelen nameof keyword\u00fcne de\u011finece\u011fiz.<\/p>\n

\u00d6rnek olarak ArgumentNullException s\u0131n\u0131f\u0131n\u0131 ele alabiliriz. Bu s\u0131n\u0131ftan bir nesne olu\u015ftururken constructer\u0131nda “paramName” isimli parametre ile, kontrol edilen parametrenin ismini string olarak vermekteyiz.<\/p>\n
