설명
새 인스턴스를 만들려면이 메서드를 사용 합니다 X509EnhancedKeyUsageExtension 클래스입니다. 인스턴스를 만든 후 사용할 수는 EnhancedKeyUsages 속성을 개체 식별자 (Oid) 키를 사용 하는 애플리케이션을 나타내는 컬렉션을 가져옵니다.
적용 대상
X509EnhancedKeyUsageExtension(AsnEncodedData, Boolean)
X509EnhancedKeyUsageExtension 개체와 확장이 중요한지 여부를 식별하는 값을 사용하여 AsnEncodedData 클래스의 새 인스턴스를 초기화합니다.
public:

new System.Security.Cryptography.X509Certificates.X509EnhancedKeyUsageExtension : System.Security.Cryptography.OidCollection * bool -> System.Security.Cryptography.X509Certificates.X509EnhancedKeyUsageExtension
Public Sub New (enhancedKeyUsages As OidCollection, critical As Boolean)
매개 변수
- enhancedKeyUsages
- OidCollection
OidCollection 컬렉션입니다.
- critical
- Boolean
중요한 확장이면 true
이고, 그렇지 않으면 false
입니다.
예외
