X509Certificate Class

ASN.1 DER is the only certificate format supported by this class.

For most scenarios, you should use the X509Certificate2 class instead.

The following example loads an X.509 certificate from a file, calls the ToString method, and displays the results to the console.

using namespace System;
using namespace System::Security::Cryptography::X509Certificates;
int main()
{

   // The path to the certificate.
   String^ Certificate = L"Certificate.cer";

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

   // Get the value.
   String^ resultsTrue = cert->ToString( true );

   // Display the value to the console.
   Console::WriteLine( resultsTrue );

   // Get the value.
   String^ resultsFalse = cert->ToString( false );

   // Display the value to the console.
   Console::WriteLine( resultsFalse );
}
