Örnekler

Aşağıdaki örnekte , , , , BufferWidthWindowWidthWindowHeight, BufferHeightve CursorVisible özellikleri ile SetWindowPosition, SetBufferSizeve ReadKey yöntemleri gösterilmektedir.WindowLeftWindowTop Örnek, ekran arabelleği genişliğine göre ekran arabelleğine bir kılavuz deseni çizer. Ardından örnek, konsol penceresini YUKARı OK, AŞAĞI OK, SOL OK veya SAĞ OK konsol tuşlarından hangisine basıldığına yanıt olarak taşır. Kılavuz deseni, konsol penceresinin ekran arabelleğine göre hareketini görmenize yardımcı olur.
