Exemples

L’exemple de code suivant importe des informations de clé RSAParameters créées à partir RSACryptoServiceProvider d’un objet dans un objet.The following code example imports key information created from an RSAParameters object into an RSACryptoServiceProvider object.

try
{
   //Create a new RSACryptoServiceProvider object. 
   RSACryptoServiceProvider^ RSA = gcnew RSACryptoServiceProvider;
   
   //Export the key information to an RSAParameters object.
   //Pass false to export the public key information or pass
   //true to export public and private key information.
   RSAParameters RSAParams = RSA->ExportParameters( false );
   
   //Create another RSACryptoServiceProvider object.
   RSACryptoServiceProvider^ RSA2 = gcnew RSACryptoServiceProvider;
   
   //Import the key information from the other 
   //RSACryptoServiceProvider object.  
   RSA2->ImportParameters( RSAParams );
}
catch ( CryptographicException^ e ) 
{
   //Catch this exception in case the encryption did
   //not succeed.
   Console::WriteLine( e->Message );
}
try
{
    //Create a new RSACryptoServiceProvider object. 
    using (RSACryptoServiceProvider RSA = new RSACryptoServiceProvider())
    {
        //Export the key information to an RSAParameters object.
        //Pass false to export the public key information or pass
        //true to export public and private key information.
        RSAParameters RSAParams = RSA.ExportParameters(false);

        //Create another RSACryptoServiceProvider object.
        using (RSACryptoServiceProvider RSA2 = new RSACryptoServiceProvider())
        {
        //Import the key information from the other 
        //RSACryptoServiceProvider object.  
        RSA2.ImportParameters(RSAParams);
        }
    }


}
catch (CryptographicException e)
{
    //Catch this exception in case the encryption did
    //not succeed.
    Console.WriteLine(e.Message);

}
