Example

Följande kodexempel visar hur du implementerar Create metoden i en utökad klass. Det här kodexemplet är en del av ett större exempel för AsymmetricAlgorithm klassen.

// The create function attempts to create a CustomCrypto object using
// the assembly name. This functionality requires modification of the
// machine.config file. Add the following section to the configuration
// element and modify the values of the cryptoClass to reflect what is
// installed in your machines GAC.
//        <cryptoClass CustomCrypto="Contoso.CustomCrypto, 
//          CustomCrypto, 
//          Culture=neutral,
