List<T>.InsertRange(Int32, IEnumerable<T>) 메서드

정의

List<T>의 지정된 인덱스에 컬렉션의 요소를 삽입합니다.Inserts the elements of a collection into the List<T> at the specified index.

public:
 void InsertRange(int index, System::Collections::Generic::IEnumerable<T> ^ collection);
public void InsertRange (int index, System.Collections.Generic.IEnumerable<T> collection);
member this.InsertRange : int * seq<'T> -> unit
Public Sub InsertRange (index As Integer, collection As IEnumerable(Of T))

매개 변수

index
Int32

새 요소가 삽입되어야 하는 0부터 시작하는 인덱스입니다.The zero-based index at which the new elements should be inserted.

collection
IEnumerable<T>

요소가 List<T>에 삽입되어야 하는 컬렉션입니다.The collection whose elements should be inserted into the List<T>. 컬렉션 자체가 null일 수는 없지만 null형식이 참조 형식인 경우 T인 요소를 포함할 수 있습니다.The collection itself cannot be null, but it can contain elements that are null, if type T is a reference type.

예외

collectionnull입니다.collection is null.

index가 0보다 작은 경우index is less than 0.

또는-or- indexCount보다 큰 경우index is greater than Count.

예제

다음 예제에서는 InsertRange 메서드와 범위에서 작동 하는 List<T> 클래스의 여러 다른 메서드를 보여 줍니다.The following example demonstrates InsertRange method and various other methods of the List<T> class that act on ranges. 목록이 만들어지고 여러 여 dinosaurs 이름으로 채워진 후에는 인덱스 위치 3에서 시작 하 여 ferocious의 세 가지 배열을 목록에 삽입 하는 데 InsertRange 메서드가 사용 됩니다.After the list has been created and populated with the names of several peaceful plant-eating dinosaurs, the InsertRange method is used to insert an array of three ferocious meat-eating dinosaurs into the list, beginning at index location 3.

설명

List<T>은 참조 형식에 대해 유효한 값으로 null을 허용 하며 중복 요소를 허용 합니다.List<T> accepts null as a valid value for reference types and allows duplicate elements.

Count (현재 Count 및 컬렉션 크기)가 Capacity보다 큰 경우 새 요소를 수용할 수 있도록 내부 배열을 자동으로 재할당 하 여 List<T> 용량이 늘어나고 새 요소가 추가 되기 전에 기존 요소가 새 배열에 복사 됩니다.If the new Count (the current Count plus the size of the collection) will be greater than Capacity, the capacity of the List<T> is increased by automatically reallocating the internal array to accommodate the new elements, and the existing elements are copied to the new array before the new elements are added.

index Count와 같으면 요소가 List<T>끝에 추가 됩니다.If index is equal to Count, the elements are added to the end of List<T>.

컬렉션의 요소 순서는 List<T>에서 유지 됩니다.The order of the elements in the collection is preserved in the List<T>.

이 메서드는 O (n * m) 연산입니다. 여기서 n 은 추가할 요소의 수이 고 mCount입니다.This method is an O(n * m) operation, where n is the number of elements to be added and m is Count.
