Ejemplos

En el ejemplo de código siguiente se muestra cómo invalidar la propiedad KeySize para comprobar que se encuentra dentro del intervalo identificado en la variable local keySizes miembro.The following code example demonstrates how to override the KeySize property to verify that it falls within the range identified in the local keySizes member variable. Este ejemplo de código forma parte de un ejemplo más extenso proporcionado para la clase AsymmetricAlgorithm.This code example is part of a larger example provided for the AsymmetricAlgorithm class.

Comentarios

Los tamaños de clave válidos se especifican mediante la implementación concreta del algoritmo asimétrico y se enumeran en la propiedad LegalKeySizes.The valid key sizes are specified by the particular implementation of the asymmetric algorithm and are listed in the LegalKeySizes property.
