Beispiel

Im folgenden Codebeispiel wird veranschaulicht, wie die Create -Methode in einer erweiterten Klasse implementiert wird. Dieses Codebeispiel ist Teil eines größeren Beispiels, das für die AsymmetricAlgorithm-Klasse bereitgestellt wird.

    // 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 isinstalled 
    // in your machines GAC.
    //        <cryptoClass CustomCrypto="Contoso.CustomCrypto,
    //          CustomCrypto,
    //          Culture=neutral,
