  • 참조

정의

네임스페이스:
System.Web.Configuration
어셈블리:
System.Web.dll

브라우저가 웹 탐색기 검색 엔진인지 여부를 나타내는 값을 가져옵니다.

public:
 property bool Crawler { bool get(); };
public bool Crawler { get; }
member this.Crawler : bool
Public ReadOnly Property Crawler As Boolean

속성 값

Boolean

브라우저가 검색 엔진이면 true이고, 그렇지 않으면 false입니다. 기본값은 false입니다.
