Hinweise

Diese Methode ist in .NET 5 und höheren Versionen veraltet.

Example

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 is
// installed in your machines GAC.
//        <cryptoClass CustomCrypto="Contoso.CustomCrypto, 
//          CustomCrypto, 
//          Culture=neutral, 
//          PublicKeyToken=fdb9f9c4851028bf, 
//          Version=1.0.1448.27640" />
//      <nameEntry name="Contoso.CustomCrypto" class="CustomCrypto" />
//      <nameEntry name="CustomCrypto" class="CustomCrypto" />
new static public CustomCrypto Create() 
{
    return Create("CustomCrypto");
}
