Definizione

Restituisce i parametri dell'algoritmo delle chiavi per il certificato X.509v3 sotto forma di matrice di byte.Returns the key algorithm parameters for the X.509v3 certificate as an array of bytes.

public:
 virtual cli::array <System::Byte> ^ GetKeyAlgorithmParameters();
public virtual byte[] GetKeyAlgorithmParameters ();
abstract member GetKeyAlgorithmParameters : unit -> byte[]

Public Overridable Function GetKeyAlgorithmParameters () As Byte()

Restituisce

Byte[]

Parametri dell'algoritmo delle chiavi per il certificato X.509 sotto forma di matrice di byte.The key algorithm parameters for the X.509 certificate as an array of bytes.

Eccezioni

Il contesto del certificato non è valido.The certificate context is invalid.

Esempi

Nell'esempio seguente viene usato il metodo GetKeyAlgorithmParameters per restituire i parametri dell'algoritmo chiave del certificato come matrice di byte e visualizzarli nella console.The following example uses the GetKeyAlgorithmParameters method to return a certificate's key algorithm parameters as an array of bytes and displays it to the console.

using namespace System;
using namespace System::Security::Cryptography::X509Certificates;
int main()
{
   
   // The path to the certificate.
   String^ Certificate = "Certificate.cer";
   
   // Load the certificate into an X509Certificate object.
   X509Certificate^ cert = X509Certificate::CreateFromCertFile( Certificate );
   
   // Get the value.
   array<Byte>^results = cert->GetKeyAlgorithmParameters();
   
   // Display the value to the console.
   System::Collections::IEnumerator^ enum0 = results->GetEnumerator();
   while ( enum0->MoveNext() )
   {
      Byte b = safe_cast<Byte>(enum0->Current);
      Console::Write( b );
   }
}


using System;
using System.Security.Cryptography.X509Certificates;


public class X509
{

    public static void Main()
    {

        // The path to the certificate.
        string Certificate =  "Certificate.cer";

        // Load the certificate into an X509Certificate object.
        X509Certificate cert = X509Certificate.CreateFromCertFile(Certificate);

        // Get the value.
        byte[] results = cert.GetKeyAlgorithmParameters();
       
        // Display the value to the console.
        foreach(byte b in results)
        {
            Console.Write(b);
        }
  
    }

}
