The following example uses the GetExpirationDateString method to get the expiration date of a certificate and displays it to the console.
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. String^ results = cert->GetExpirationDateString(); // Display the value to the console. Console::WriteLine( results ); }
