Exemplos

O exemplo de código a seguir abre o repositório de certificados pessoal do usuário atual, permite que você selecione um certificado e, em seguida, grava informações de cadeia de certificados e certificados no console. A saída depende do certificado selecionado.

//Output chain information of the selected certificate.
X509Chain ^ ch = gcnew X509Chain;
ch->ChainPolicy->RevocationMode = X509RevocationMode::Online;
ch->Build( certificate );
Console::WriteLine( "Chain Information" );
Console::WriteLine( "Chain revocation flag: {0}", ch->ChainPolicy->RevocationFlag );
Console::WriteLine( "Chain revocation mode: {0}", ch->ChainPolicy->RevocationMode );
Console::WriteLine( "Chain verification flag: {0}", ch->ChainPolicy->VerificationFlags );
Console::WriteLine( "Chain verification time: {0}", ch->ChainPolicy->VerificationTime );
Console::WriteLine( "Chain status length: {0}", ch->ChainStatus->Length );
Console::WriteLine( "Chain application policy count: {0}", ch->ChainPolicy->ApplicationPolicy->Count );
Console::WriteLine( "Chain certificate policy count: {0} {1}", ch->ChainPolicy->CertificatePolicy->Count, Environment::NewLine );

X509Chain(Boolean)

Origem:

X509Chain.cs

Inicializa uma nova instância da classe X509Chain especificando um valor que indica se o contexto do computador deve ser usado.

public:
 X509Chain(bool useMachineContext);

public X509Chain (bool useMachineContext);

new System.Security.Cryptography.X509Certificates.X509Chain : bool -> System.Security.Cryptography.X509Certificates.X509Chain

Public Sub New (useMachineContext As Boolean)

Parâmetros

useMachineContext

Boolean

true para usar o contexto do computador, false para usar o contexto do usuário atual.

Comentários

Esse construtor pode ser usado quando o perfil do usuário não é carregado e o contexto do computador precisa ser usado. Quando o useMachineContext parâmetro é definido como true, o contexto do computador local (HCCE_LOCAL_MACHINE sinalizador) é usado para criar a cadeia. Se o parâmetro for definido como false, o contexto do usuário atual (HCCE_CURRENT_USER sinalizador) será usado.

X509Chain(IntPtr)

Origem:

X509Chain.cs

Inicializa uma nova instância da classe X509Chain usando um identificador IntPtr para uma cadeia X.509.

[<System.Runtime.Versioning.SupportedOSPlatform("windows")>]
new System.Security.Cryptography.X509Certificates.X509Chain : nativeint -> System.Security.Cryptography.X509Certificates.X509Chain

Public Sub New (chainContext As IntPtr)
