Ausnahmen

Ausnahmetyp	Bedingung
CryptographicException	Der Schlüssel kann nicht exportiert werden.

Beispiel

Im folgenden Codebeispiel werden Schlüsselinformationen von einem DSACryptoServiceProvider-Objekt in ein DSAParameters-Objekt exportiert.

Try
    'Create a new DSACryptoServiceProvider object.
    Dim DSA As New DSACryptoServiceProvider()


    'Export the key information to an DSAParameters object.
    'Pass false to export the public key information or pass
    'true to export public and private key information.
    Dim DSAParams As DSAParameters = DSA.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 DSACryptoServiceProvider object.
    DSACryptoServiceProvider DSA = new DSACryptoServiceProvider();


    //Export the key information to an DSAParameters object.
    //Pass false to export the public key information or pass
    //true to export public and private key information.
    DSAParameters DSAParams = DSA.ExportParameters(false);


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

}

try
{
   //Create a new DSACryptoServiceProvider object.
   DSACryptoServiceProvider^ DSA = gcnew DSACryptoServiceProvider;
   
   //Export the key information to an DSAParameters object.
   //Pass false to export the public key information or pass
   //true to export public and private key information.
   DSAParameters DSAParams = DSA->ExportParameters( false );
}
catch ( CryptographicException^ e ) 
{
   //Catch this exception in case the encryption did
   //not succeed.
   Console::WriteLine( e->Message );
}

try {
    // Create a new DSACryptoServiceProvider object.
    DSACryptoServiceProvider dsa = new DSACryptoServiceProvider();

    // Export the key information to an DSAParameters object.
    // Pass false to export the public key information or pass
    // true to export public and private key information.
    DSAParameters dsaParams = dsa.ExportParameters(false);
}
catch (CryptographicException e) {
    // Catch this exception in case the encryption did
    // not succeed.
    Console.WriteLine(e.get_Message());
}
