flag 매개 변수에 지정된 특징을 사용하여 고유 이름을 디코딩합니다.

public:
 System::String ^ Decode(System::Security::Cryptography::X509Certificates::X500DistinguishedNameFlags flag);

public string Decode (System.Security.Cryptography.X509Certificates.X500DistinguishedNameFlags flag);

member this.Decode : System.Security.Cryptography.X509Certificates.X500DistinguishedNameFlags -> string

Public Function Decode (flag As X500DistinguishedNameFlags) As String

매개 변수

flag

X500DistinguishedNameFlags

고유 이름의 특성을 지정하는 열거형 값의 비트 조합입니다.

반환

String

디코딩한 고유 이름입니다.

예외

CryptographicException

인증서의 이름이 잘못되었습니다.
