public:
 virtual cli::array <System::Byte> ^ GetSerialNumber();
public virtual byte[] GetSerialNumber ();
abstract member GetSerialNumber : unit -> byte[]
override this.GetSerialNumber : unit -> byte[]
Public Overridable Function GetSerialNumber () As Byte()

Devoluciones

Byte[]

Número de serie del certificado X.509 en forma de matriz de bytes en orden little-endian.

Excepciones

El contexto de certificado no es válido.

Ejemplos

En el ejemplo siguiente se usa el método para devolver el GetSerialNumber número de serie de un certificado como una matriz de bytes y se muestra en la consola.

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->GetSerialNumber();
   
   // 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.GetSerialNumber();

        // 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.GetSerialNumber()
      
      ' Display the value to the console.
      Dim b As Byte
      For Each b In  results
         Console.Write(b)
