Merhaba,<\/p>\n

Bu i\u00e7eri\u011fimizde, kendisini uygulayan s\u0131n\u0131fta kendi tipindeki nesnelere kar\u015f\u0131 nas\u0131l bir kar\u015f\u0131la\u015ft\u0131rma yap\u0131laca\u011f\u0131n\u0131 belirlemek i\u00e7in kullan\u0131lan IComparable Interface’ine de\u011finece\u011fiz.<\/p>\n

IComparable Interface’i, miras alan s\u0131n\u0131fa CompareTo metodunu uygulatmakta ve bu metot arac\u0131l\u0131\u011f\u0131yla kar\u015f\u0131la\u015ft\u0131rmay\u0131 sa\u011flamaktad\u0131r.<\/p>\n

Biliyoruz ki, Array s\u0131n\u0131f\u0131n\u0131n static Sort metodu ile elimizdeki de\u011fer tipli verileri yani basit veri tiplerini s\u0131ralabiliyoruz. Lakin referans tipli verileri yani nesneleri s\u0131ralamaya \u00e7al\u0131\u015f\u0131rken ilgili fonksiyonu kullanam\u0131yoruz. Bunun sebebi, nesnelerin hangi \u00f6zelli\u011fine g\u00f6re s\u0131ralama i\u015flemi yapaca\u011f\u0131n\u0131 Array.Sort metodunun bilememesidir.<\/p>\n
