Exporta o 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

includePrivateParameters

Boolean

true para incluir parâmetros particulares; caso contrário, false.

Retornos

RSAParameters

Os parâmetros para RSA.

Exceções

CryptographicException

A chave não pode ser exportada.

Exemplos

O exemplo de código a seguir exporta as informações de chave criadas usando o RSACryptoServiceProvider em um RSAParameters objeto .

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
