![]() ![]() | IDeserializationCallback::OnDeserialization | Implements the ISerializable interface and is called back by the deserialization event when deserialization is complete. |
![]() ![]() | ISerializable::GetObjectData | Gets serialization information with all the data needed to recreate an instance of the current X509Certificate object. |
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 ); }
