속성 값
텍스트 상자에서 현재 선택한 텍스트를 나타내는 문자열입니다.
설명
이 속성에 텍스트를 입력하여 텍스트 상자에서 현재 선택한 텍스트를 변경할 수 있습니다. 텍스트 상자에 텍스트가 선택되어 있지 않은 경우 이 속성은 길이가 0인 문자열을 반환합니다.
예제
다음 코드 예제에서는 파생 클래스인 TextBox를 사용합니다. 이 클래스에서는 잘라내기, 복사, 붙여넣기 및 실행 취소 작업을 수행하는 MenuItem 개체의 Click 이벤트 처리기가 제공됩니다. 이 예제를 실행하려면 textBox1이라는 TextBox 컨트롤을 만들어야 합니다.
