SslStream.RemoteCertificate Właściwość

Definicja

Pobiera certyfikat używany do uwierzytelniania zdalnego punktu końcowego.

public:
 virtual property System::Security::Cryptography::X509Certificates::X509Certificate ^ RemoteCertificate { System::Security::Cryptography::X509Certificates::X509Certificate ^ get(); };
public virtual System.Security.Cryptography.X509Certificates.X509Certificate? RemoteCertificate { get; }
public virtual System.Security.Cryptography.X509Certificates.X509Certificate RemoteCertificate { get; }
member this.RemoteCertificate : System.Security.Cryptography.X509Certificates.X509Certificate
Public Overridable ReadOnly Property RemoteCertificate As X509Certificate

Wartość właściwości

Obiekt X509Certificate, który reprezentuje certyfikat dostarczony do uwierzytelniania lub null jeśli nie podano certyfikatu.

Wyjątki

Uwierzytelnianie nie powiodło się lub nie wystąpiło.

Przykłady

Poniższy przykład kodu pokazuje wyświetlanie certyfikatu zwróconego przez tę właściwość.

   static void DisplayCertificateInformation( SslStream^ stream )
   {
      Console::WriteLine( L"Certificate revocation list checked: {0}", stream->CheckCertRevocationStatus );
      X509Certificate^ localCertificate = stream->LocalCertificate;
      if ( stream->LocalCertificate != nullptr )
      {
         Console::WriteLine( L"Local cert was issued to {0} and is valid from {1} until {2}.", 
             localCertificate->Subject, 
             localCertificate->GetEffectiveDateString(), 
             localCertificate->GetExpirationDateString() );
      }
      else
      {
         Console::WriteLine( L"Local certificate is null." );
      }

      X509Certificate^ remoteCertificate = stream->RemoteCertificate;
      if ( stream->RemoteCertificate != nullptr )
      {
         Console::WriteLine( L"Remote cert was issued to {0} and is valid from {1} until {2}.",

         Console::WriteLine( L"Remote certificate is null." );
      }
   }


private:
static void DisplayCertificateInformation(SslStream stream)
{
    Console.WriteLine("Certificate revocation list checked: {0}", stream.CheckCertRevocationStatus);

    X509Certificate localCertificate = stream.LocalCertificate;
    if (stream.LocalCertificate != null)
    {
        Console.WriteLine("Local cert was issued to {0} and is valid from {1} until {2}.",

            localCertificate.GetExpirationDateString());
     } else
    {
        Console.WriteLine("Local certificate is null.");
    }
    // Display the properties of the client's certificate.
    X509Certificate remoteCertificate = stream.RemoteCertificate;
    if (stream.RemoteCertificate != null)
    {

        Console.WriteLine("Remote certificate is null.");
    }
}
Private Shared Sub DisplayCertificateInformation(stream As SslStream)
    Console.WriteLine("Certificate revocation list checked: {0}", stream.CheckCertRevocationStatus)
    Dim localCertificate As X509Certificate = stream.LocalCertificate

    If stream.LocalCertificate IsNot Nothing Then
        Console.WriteLine("Local cert was issued to {0} and is valid from {1} until {2}.", localCertificate.Subject, localCertificate.GetEffectiveDateString(), localCertificate.GetExpirationDateString())
    Else
        Console.WriteLine("Local certificate is null.")
    End If

    ' Display the properties of the client's certificate.
    Dim remoteCertificate As X509Certificate = stream.RemoteCertificate

    If stream.RemoteCertificate IsNot Nothing Then
        Console.WriteLine("Remote cert was issued to {0} and is valid from {1} until {2}.", remoteCertificate.Subject, remoteCertificate.GetEffectiveDateString(), remoteCertificate.GetExpirationDateString())
    Else
        Console.WriteLine("Remote certificate is null.")
    End If
End Sub

Uwagi

Jeśli dostęp do właściwości jest uzyskiwany, certyfikat zdalny nie zostanie usunięty, gdy wystąpienie SslStream zostanie usunięte. Obiekt wywołujący właściwości jest odpowiedzialny za dysponowanie zwróconego X509Certificate obiektu.
