Bir koleksiyonun öğelerini içindeki ArrayListbir öğe aralığına kopyalar.

public:
 virtual void SetRange(int index, System::Collections::ICollection ^ c);

public virtual void SetRange (int index, System.Collections.ICollection c);

abstract member SetRange : int * System.Collections.ICollection -> unit
override this.SetRange : int * System.Collections.ICollection -> unit

Public Overridable Sub SetRange (index As Integer, c As ICollection)

Parametreler

index

Int32

öğelerini ckopyalamaya başlanacak sıfır tabanlı ArrayList dizin.

c

ICollection

ICollection öğelerinin öğesine kopyalanması gereken ArrayList. Koleksiyonun kendisi olamaz null, ancak olan nullöğeleri içerebilir.

Özel durumlar

ArgumentOutOfRangeException

index, sıfırdan küçüktür.

-veya-

index artı içindeki c öğelerin sayısı değerinden Countbüyüktür.

ArgumentNullException

c, null değeridir.

NotSupportedException

ArrayList salt okunurdur.
