StringCollection.Insert(Int32, String) 메서드

정의

지정한 인덱스에 있는 StringCollection에 문자열을 삽입합니다.Inserts a string into the StringCollection at the specified index.

public:
 void Insert(int index, System::String ^ value);
public void Insert (int index, string value);
member this.Insert : int * string -> unit
Public Sub Insert (index As Integer, value As String)

매개 변수

index
Int32

value을 삽입할 인덱스(0부터 시작)입니다.The zero-based index at which value is inserted.

value
String

삽입할 문자열입니다.The string to insert. 값은 null이 될 수 있습니다.The value can be null.

예외

index가 0보다 작은 경우index is less than zero.

-또는--or- indexCount보다 큽니다.index greater than Count.

예제

다음 코드 예제에서는 StringCollection에 새 요소를 추가 합니다.The following code example adds new elements to the StringCollection.

#using <System.dll>

using namespace System;
using namespace System::Collections;
using namespace System::Collections::Specialized;
void PrintValues( IEnumerable^ myCol );
int main()
{
   
   // Creates and initializes a new StringCollection.
   StringCollection^ myCol = gcnew StringCollection;
   Console::WriteLine( "Initial contents of the StringCollection:" );
   PrintValues( myCol );
   
   // Adds a range of elements from an array to the end of the StringCollection.
   array<String^>^myArr = {"RED","orange","yellow","RED","green","blue","RED","indigo","violet","RED"};
   myCol->AddRange( myArr );
   Console::WriteLine( "After adding a range of elements:" );
   PrintValues( myCol );
   
   // Adds one element to the end of the StringCollection and inserts another at index 3.
   myCol->Add( "* white" );
   myCol->Insert( 3, "* gray" );
   Console::WriteLine( "After adding \"* white\" to the end and inserting \"* gray\" at index 3:" );
   PrintValues( myCol );
}

void PrintValues( IEnumerable^ myCol )
{
   IEnumerator^ myEnum = myCol->GetEnumerator();
   while ( myEnum->MoveNext() )
   {
      Object^ obj = safe_cast<Object^>(myEnum->Current);
      Console::WriteLine( "   {0}", obj );
   }

   Console::WriteLine();
}

설명

StringCollection에서 중복 문자열을 사용할 수 있습니다.Duplicate strings are allowed in StringCollection.

하는 경우 index 값과 같음 Countvalue 끝에 추가 됩니다 StringCollection합니다.If index is equal to Count, value is added to the end of StringCollection.

목록처럼 연속된 요소로 구성된 컬렉션에서는 삽입 지점 다음에 있는 요소를 아래로 이동하여 새 요소로 적용합니다.In collections of contiguous elements, such as lists, the elements that follow the insertion point move down to accommodate the new element. 컬렉션에 인덱스가 지정된 경우 이동되는 요소의 인덱스도 업데이트됩니다.If the collection is indexed, the indexes of the elements that are moved are also updated. 요소가 해시 테이블 같은 버킷으로 개념적으로 그룹화되어 있는 컬렉션에는 이러한 동작이 적용되지 않습니다.This behavior does not apply to collections where elements are conceptually grouped into buckets, such as a hash table.

이 메서드는 O (n) 작업, 여기서 nCount합니다.This method is an O(n) operation, where n is Count.
