The name of a certificate file represented as a string.

This method uses a certificate file (such as a file with a .cer extension) that represents an X.509 certificate, and populates the X509Certificate object with the certificate that the file contains.

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;
   cert->Import(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 );
}
