    includePrivateParameters As Boolean _
) As RSAParameters
'Usage
Dim instance As RSACryptoServiceProvider
Dim includePrivateParameters As Boolean
Dim returnValue As RSAParameters

returnValue = instance.ExportParameters(includePrivateParameters)

public override RSAParameters ExportParameters (
    bool includePrivateParameters
)

public:
virtual RSAParameters ExportParameters (
    bool includePrivateParameters
) override

    boolean includePrivateParameters
)

Parameter

true, wenn private Parameter angegeben werden sollen, andernfalls false.

Rückgabewert

Die Parameter für RSA.

Ausnahmen

Ausnahmetyp	Bedingung
CryptographicException	Der Schlüssel kann nicht exportiert werden.

Beispiel

Im folgenden Codebeispiel werden die mit dem RSACryptoServiceProvider erstellten Schlüsselinformationen in ein RSAParameters-Objekt exportiert.

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

try
{
    //Create a new RSACryptoServiceProvider object.
    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*.
   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.
    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.get_Message());
}
