정의

네임스페이스:

System.Windows.Forms

어셈블리:

System.Windows.Forms.dll

컬렉션에서 지정된 인덱스의 탭 페이지를 제거합니다.

public:
 virtual void RemoveAt(int index);

public void RemoveAt (int index);

abstract member RemoveAt : int -> unit
override this.RemoveAt : int -> unit

Public Sub RemoveAt (index As Integer)

매개 변수

index

Int32

제거할 TabPage의 인덱스(0부터 시작)입니다.

구현

RemoveAt(Int32)

예제

다음 코드 예제에서는 처음에 3TabPage을 사용하여 TabControl 만듭니다. 이 예제에서는 메서드를 RemoveAt 사용하여 컨트롤 컬렉션에서 인덱스로 지정된 메서드를 tabControl1 제거tabPage1합니다. 이 속성은 TabPages 이 컬렉션에서 tabControl1 탭 페이지를 추가하고 제거할 컨트롤 컬렉션을 가져옵니다.
