Örnekler

Aşağıdaki örnek, sabit listesi değerlerini ConsoleColor bir diziye kaydeder ve ve ForegroundColor özelliklerinin geçerli değerlerini BackgroundColor değişkenlere depolar. Ardından ön plan rengini, geçerli arka planla eşleşen renk dışında numaralandırmadaki ConsoleColor her renkle değiştirir ve arka plan rengini, geçerli ön planla eşleşen renk dışında numaralandırmadaki ConsoleColor her renge değiştirir. (Ön plan rengi arka plan rengiyle aynıysa, metin görünmez.) Son olarak, özgün konsol renklerini geri yüklemek için yöntemini çağırır ResetColor .

Windows tabanlı bir uygulama için bir konsolun mevcut olmadığı bir get işlemi döndürürConsoleColor.Black. Unix sistemleri, geçerli konsol renklerini getirmek için genel bir mekanizma sağlamaz. Bu nedenle, BackgroundColor açık bir şekilde ayarlanana kadar döndürür (ConsoleColor)-1 (ayarlayıcı kullanılarak).
