X509Certificate.GetKeyAlgorithmParameters 方法

定義

傳回做為位元組陣列的 X.509v3 憑證金鑰演算法參數。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[]
override this.GetKeyAlgorithmParameters : unit -> byte[]
Public Overridable Function GetKeyAlgorithmParameters () As Byte()

傳回

Byte[]

做為位元組陣列的 X.509 憑證金鑰演算法參數。The key algorithm parameters for the X.509 certificate as an array of bytes.

例外狀況

憑證內容無效。The certificate context is invalid.

範例

下列範例會使用 GetKeyAlgorithmParameters 方法,以位元組陣列形式傳回憑證的金鑰演算法參數,並將它顯示在主控台中。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);
        }
  
    }

}
Imports System.Security.Cryptography.X509Certificates




Public Class X509
   
   
   Public Shared Sub Main()
      
      ' The path to the certificate.
      Dim Certificate As String = "Certificate.cer"
      
      ' Load the certificate into an X509Certificate object.
      Dim cert As X509Certificate = X509Certificate.CreateFromCertFile(Certificate)
      
      ' Get the value.
      Dim results As Byte() = cert.GetKeyAlgorithmParameters()
      
      ' Display the value to the console.
      Dim b As Byte
      For Each b In  results
         Console.Write(b)
      Next b
   End Sub  
End Class
