SslStream.LocalCertificate プロパティ

定義

ローカル エンドポイントの認証に使用する証明書を取得します。Gets the certificate used to authenticate the local endpoint.

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

プロパティ値

X509Certificate

認証用に提供された証明書を表す X509Certificate オブジェクト。証明書が提供されなかった場合は nullAn X509Certificate object that represents the certificate supplied for authentication or null if no certificate was supplied.

例外

認証に失敗したか、認証が行われていません。Authentication failed or has not occurred.

次のコード例は、このプロパティによって返される証明書を表示する方法を示しています。The following code example demonstrates displaying the certificate returned by this property.

   static void DisplayCertificateInformation( SslStream^ stream )

      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." );
      }

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