Ejemplos

En el ejemplo siguiente se emite un ensamblado dinámico y se guarda en el directorio actual. Cuando se crea el ensamblado, la KeyPair propiedad se usa para establecer las claves criptográficas públicas y privadas del ensamblado.

Comentarios

Cuando el tiempo de ejecución carga un ensamblado, no establece la KeyPair propiedad . El captador de la propiedad solo es útil si el usuario establece la propiedad antes de usar el AssemblyName objeto para crear un ensamblado dinámico y, posteriormente, desea recuperar el par de claves.
