AddAllAsync<TItem>(int, ICollection<TItem>)

Inserts all of the elements in the specified collection into this list at the specified position.

Declaration

Task<bool> AddAllAsync<TItem>(int index, ICollection<TItem> items) where TItem : T

Parameters

int	index	index at which to insert the first element from the specified collection
ICollection<TItem>	items	collection containing elements to be added to this list

Returns

Task<bool>

true if this list changed as a result of the call

Type Parameters

TItem

Remarks

Shifts the element currently at that position (if any) and any subsequent elements to the right (increases their indices). The new elements will appear in this list in the order that they are returned by the specified collection's iterator. The behavior of this operation is undefined if the specified collection is modified while the operation is in progress. (Note that this will occur if the specified collection is this list, and it's nonempty.)
