Assembly:  System (in System.dll)

public:
String^ Decode(
	X500DistinguishedNameFlags flag
)

Parameters

flag
Type: System.Security.Cryptography.X509Certificates::X500DistinguishedNameFlags

A bitwise combination of the enumeration values that specify the characteristics of the distinguished name.

Return Value

Type: System::String^

The decoded distinguished name.

Exception Condition
CryptographicException

The certificate has an invalid name.

This method decodes the ASN encoded distinguished name into a string value.

The following code example shows how to use the X500DistinguishedName class.

#using <System.dll>
#using <system.security.dll>

using namespace System;
using namespace System::Security::Cryptography;
using namespace System::Security::Permissions;
using namespace System::IO;
using namespace System::Security::Cryptography::X509Certificates;
int main()
{
   try
   {
      X509Store ^ store = gcnew X509Store( "MY",StoreLocation::CurrentUser );
      store->Open( static_cast<OpenFlags>(OpenFlags::ReadOnly | OpenFlags::OpenExistingOnly) );
      X509Certificate2Collection ^ collection = dynamic_cast<X509Certificate2Collection^>(store->Certificates);
      X509Certificate2Collection ^ fcollection = dynamic_cast<X509Certificate2Collection^>(collection->Find( X509FindType::FindByTimeValid, DateTime::Now, false ));
      X509Certificate2Collection ^ scollection = X509Certificate2UI::SelectFromCollection(fcollection, "Test Certificate Select","Select a certificate from the following list to get information on that certificate",X509SelectionFlag::MultiSelection);
      Console::WriteLine( "Number of certificates: {0}{1}", scollection->Count, Environment::NewLine );
      System::Collections::IEnumerator^ myEnum = scollection->GetEnumerator();
      while ( myEnum->MoveNext() )
      {
         X509Certificate2 ^ x509 = safe_cast<X509Certificate2 ^>(myEnum->Current);
         X500DistinguishedName ^ dname = gcnew X500DistinguishedName( x509->SubjectName );
         Console::WriteLine( "X500DistinguishedName: {0}{1}", dname->Name, Environment::NewLine );
         x509->Reset();
      }
      store->Close();
   }
   catch ( CryptographicException^ ) 
   {
      Console::WriteLine( "Information could not be written out for this certificate." );
   }
