Açıklamalar

Geçerli yöntem, geçerli örnekten belirtilen karakter aralığını kaldırır. (startIndex + length) konumundaki karakterler öğesine startIndextaşınır ve geçerli örneğin dize değeri ile lengthkısaltılır. Geçerli örneğin kapasitesi etkilenmez.

Not

Remove yöntemi geçerli StringBuilder örneğin değerini değiştirir ve bu örneği döndürür. Yeni StringBuilder bir nesne oluşturmaz ve döndürmez.
