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()

Beispiele

Im folgenden Beispiel wird die -Methode verwendet, um die GetSerialNumber Seriennummer eines Zertifikats als Bytearray zurückzugeben und in der Konsole anzuzeigen.

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;

        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);
