필드

AfterBegin	1	현재 요소 뒤, 현재 요소의 다른 모든 콘텐츠 앞에 요소를 삽입합니다.
AfterEnd	3	현재 요소 뒤, 현재 요소의 다른 모든 콘텐츠 뒤에 요소를 삽입합니다.
BeforeBegin	0	현재 요소 앞에 요소를 삽입합니다.
BeforeEnd	2	현재 요소 뒤에 요소를 삽입합니다.

예제

다음 코드 예제에서는 삽입을 DIV ADatum.com 서버 외부에서 볼 수 있는 모든 페이지의 맨 위에 있는 요소입니다. 폼이 예제는 WebBrowser 라는 컨트롤 WebBrowser1합니다. 예제의 네임 스페이스를 가져와야도 System.Text.RegularExpressions합니다.
