Esempio

Nell'esempio di codice seguente viene illustrato come aprire una chiave del Registro di sistema in un computer remoto ed enumerare i valori della chiave. Il computer remoto deve eseguire il servizio registro remoto. Specificare il nome del computer remoto come argomento della riga di comando quando si richiama il programma.

using namespace System;
using namespace System::IO;
using namespace System::Security::Permissions;
using namespace Microsoft::Win32;


int main( int argc, char *argv[] )
{
   RegistryKey ^ environmentKey;
   
   // Check that an argument was specified when the 
   // program was invoked.
   if ( argc == 1 )
   {
      Console::WriteLine( "Error: The name of the remote computer "
      "must be specified as input on the command line." );
      return  -1;
   }

   try
   {
      
      // Open HKEY_CURRENT_USER\Environment on a remote computer.
      environmentKey = RegistryKey::OpenRemoteBaseKey( RegistryHive::CurrentUser, gcnew String(argv[ 1 ]) )->OpenSubKey( "Environment" );
   }
   catch ( IOException^ e ) 
   {
      Console::WriteLine(  "{0}: {1}", e->GetType()->Name, e->Message );
      return  -1;
   }

   
   // Print the values.
   Console::WriteLine( "\nThere are {0} values for {1}.", environmentKey->ValueCount.ToString(), environmentKey->Name );
   array<String^>^valueNames = environmentKey->GetValueNames();
   for ( int i = 0; i < environmentKey->ValueCount; i++ )
   {
      Console::WriteLine(  "{0,-20}: {1}", valueNames[ i ], environmentKey->GetValue( valueNames[ i ] )->ToString() );

   }
   
   // Close the registry key.
   environmentKey->Close();
}

Commenti

RegistryHive i valori vengono utilizzati dal OpenRemoteBaseKey metodo per rappresentare il nodo di primo livello di una chiave richiesta in un computer esterno (remoto). Il nodo che può essere aperto con il metodo OpenRemoteBaseKey deve essere uno di questi elementi di primo livello RegistryKeys. È possibile accedere ulteriormente alle sottochiavi del nodo identificato usando i metodi in RegistryKey, purché l'utente disponga dell'autorizzazione appropriata.
