 static cli::array <System::String ^> ^ GetUsersInRole(System::String ^ roleName);

public static string[] GetUsersInRole (string roleName);

static member GetUsersInRole : string -> string[]

Public Shared Function GetUsersInRole (roleName As String) As String()

매개 변수

roleName: String

사용자 목록을 가져올 역할입니다.

String[]

지정된 역할의 멤버에 해당하는 모든 사용자의 이름이 포함된 문자열 배열입니다.

예외

ArgumentNullException

roleName이(가) null인 경우

ArgumentException

roleName이 빈 문자열이거나 쉼표(,)를 포함하는 경우

역할 관리가 사용되지 않는 경우

예제

다음 코드 예제에서는 메서드를 GetUsersInRole 사용하여 특정 역할의 사용자 목록을 가져와 결과를 컨트롤에 GridView 바인딩합니다. 역할 관리를 사용 하도록 설정 하는 Web.config 파일의 예제를 참조 하세요. Roles합니다.
