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

Parameters

includePrivateParameters: Boolean

true to include private parameters; otherwise, false.

Returns

RSAParameters

The parameters for RSA.

Exceptions

CryptographicException

The key cannot be exported.

Examples

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
