Merhaba,<\/p>\n

Son zamanlarda her ne kadar C# 8.0 versiyonu \u00f6zelliklerine odaklanm\u0131\u015f olsakta 7.0 versiyonunda ele almad\u0131\u011f\u0131m g\u00fczel bir manevra sa\u011flayan Deconstruct \u00f6zelli\u011fini k\u0131saca sizlerle tan\u0131\u015ft\u0131r\u0131p, esas g\u00fcncel konular\u0131m\u0131zdan yaz\u0131 ak\u0131\u015f\u0131m\u0131za devam etmek istiyorum.<\/p>\n

Deconstruct Metodu Nedir? Ne \u0130\u015flev G\u00f6r\u00fcr?<\/h3>\n

Bir s\u0131n\u0131f i\u00e7erisinde “Deconstruct<\/em>” ismiyle tan\u0131mlanan metot, compiler taraf\u0131ndan \u00f6zel olarak alg\u0131lanmakta ve s\u0131n\u0131f\u0131n nesnesi \u00fczerinden geriye h\u0131zl\u0131ca Tuple tipte bir de\u011fer d\u00f6nd\u00fcrmemizi sa\u011flamaktad\u0131r.<\/p>\n

Kullan\u0131m\u0131 \u015f\u00f6yledir;<\/p>\n

Compiler ilgili metodun \u00f6zel oldu\u011funu isminden alg\u0131layacakt\u0131r ve ilgili s\u0131n\u0131ftan olu\u015fturulan nesneler \u00fczerinde a\u015fa\u011f\u0131daki i\u015flemi yapmam\u0131za olanak tan\u0131yacakt\u0131r.<\/p>\n

Nihayetinde yine bir “Ogrenci” nesnesi Tuple kar\u015f\u0131l\u0131\u011f\u0131 olacak \u015fekilde talep edilmektedir.<\/p>\n
