Определение

Экспортирует объект RSAParameters.Exports the RSAParameters.

public:
 override System::Security::Cryptography::RSAParameters ExportParameters(bool includePrivateParameters);
public override System.Security.Cryptography.RSAParameters ExportParameters (bool includePrivateParameters);
override this.ExportParameters : bool -> System.Security.Cryptography.RSAParameters
Public Overrides Function ExportParameters (includePrivateParameters As Boolean) As RSAParameters

Параметры

includePrivateParameters
Boolean Boolean Boolean Boolean

Значение true для включения закрытых параметров; в противном случае — значение false.true to include private parameters; otherwise, false.

Возвраты

Параметры для RSA.The parameters for RSA.

Исключения

Невозможно экспортировать ключ.The key cannot be exported.

Примеры

В следующем примере кода выполняется экспорт сведений о ключе, RSACryptoServiceProvider созданных с RSAParameters помощью, в объект.The following code example exports the key information created using the RSACryptoServiceProvider into an RSAParameters 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 );
}
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);
    }


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

}
     Try

         'Create a new RSACryptoServiceProvider object. 
         Dim RSA As 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.
         Dim RSAParams As RSAParameters = RSA.ExportParameters(False)


     Catch e As CryptographicException
         'Catch this exception in case the encryption did
         'not succeed.
         Console.WriteLine(e.Message)
     End Try
