Ejemplo

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

    // 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 isinstalled 
    // in your machines GAC.
