X509Certificate Class

Provides methods that help you use X.509 v.3 certificates.

Namespace:  System.Security.Cryptography.X509Certificates
Assembly:  mscorlib (in mscorlib.dll)

[SerializableAttribute]
[ComVisibleAttribute(true)]
public ref class X509Certificate : IDeserializationCallback, 
	ISerializable

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 );
}
