설명

일반적으로 이벤트는 사용자가 컨트롤의 LinkClicked 링크를 클릭할 때 작업을 수행하기 위해 처리됩니다. 이벤트에 대한 LinkClicked 이벤트 처리기는 클릭한 링크와 연결된 개체가 포함된 LinkLabel.Link 클래스의 LinkLabelLinkClickedEventArgs instance 전달됩니다. 클래스의 LinkLabel.Link 속성에 LinkData 지정된 정보를 사용하여 클릭한 링크 또는 링크를 클릭할 때 수행할 작업 유형을 확인할 수 있습니다. 예를 들어 컨트롤 LinkLabel.LinkLinkLabel 해당 속성이 문자열www.microsoft.comLinkData 설정된 개체가 있는 경우 이벤트에 대한 LinkClicked 이벤트 처리기에서 이 정보를 사용하여 웹 사이트를 표시할 수 있습니다.
