Example

En el ejemplo de código siguiente se muestra cómo implementar el Create método en una clase extendida. Este ejemplo de código forma parte de un ejemplo más grande proporcionado para la AsymmetricAlgorithm clase .

// 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, 
//          PublicKeyToken=fdb9f9c4851028bf, 
//          Version=1.0.1448.27640" />

//      <nameEntry name="CustomCrypto" class="CustomCrypto" />
