ReadOnlyDictionary<TKey,TValue>.KeyCollection.ICollection.CopyTo(Array, Int32) 方法
定義
從特定的陣列索引開始,將集合的元素複製到陣列中。Copies the elements of the collection to an array, starting at a specific array index.
virtual void System.Collections.ICollection.CopyTo(Array ^ array, int index) = System::Collections::ICollection::CopyTo;
void ICollection.CopyTo (Array array, int index);
abstract member System.Collections.ICollection.CopyTo : Array * int -> unit
override this.System.Collections.ICollection.CopyTo : Array * int -> unit
Sub CopyTo (array As Array, index As Integer) Implements ICollection.CopyTo
參數
- array
- Array
從集合複製項目之目的端一維陣列。The one-dimensional array that is the destination of the elements copied from the collection. 陣列必須有以零為起始的索引。The array must have zero-based indexing.
- index
- Int32
array
中以零起始的索引,即開始複製的位置。The zero-based index in array
at which copying begins.
實作
例外狀況
array
為 null
。array
is null
.
index
小於 0。index
is less than 0.
array
是多維的。array
is multidimensional.
-或--or-
來源集合中的項目數目大於從 index
到目的端 array
結尾的可用空間。The number of elements in the source collection is greater than the available space from index
to the end of the destination array
.
備註
這個成員是明確介面成員實作,This member is an explicit interface member implementation. 只有在 ReadOnlyDictionary<TKey,TValue>.KeyCollection 執行個體轉換成 ICollection 介面時,才能使用這個成員。It can be used only when the ReadOnlyDictionary<TKey,TValue>.KeyCollection instance is cast to an ICollection interface.
