Açıklamalar

IndentedTextWriter, sekme dizesi ekleyen ve geçerli girinti düzeyini izleyen yöntemler sağlayarak bir TextWriter genişletir. Birden çok girinti düzeyiyle biçimlendirilmiş metin, oluşturulan kod için kullanışlıdır, bu nedenle bu sınıf CodeDOM kod oluşturucu uygulamaları tarafından kullanılır.

Sekme dizesi, her girintinin oluşturduğu dizedir. Genellikle sekme dizesi boşluk içerir.
