Определение
Важно!
Некоторые сведения относятся к предварительной версии продукта, в которую до выпуска могут быть внесены существенные изменения. Майкрософт не предоставляет никаких гарантий, явных или подразумеваемых, относительно приведенных здесь сведений.
Внимание!
Strong name signing is not supported and throws PlatformNotSupportedException.
Возвращает или задает пару открытого и закрытого ключей шифрования, которая используется для создания подписи со строгим именем для сборки.

Public Property KeyPair As StrongNameKeyPair
Значение свойства
Пара открытого и закрытого ключей шифрования, которая должна использоваться для создания подписи со строгим именем для сборки.
- Атрибуты
Исключения
Только .NET 6 и более поздних версий: во всех случаях.
Примеры
В следующем примере создается динамическая сборка и она сохраняется в текущем каталоге. При создании сборки KeyPair свойство используется для задания открытых и закрытых криптографических ключей сборки.

Комментарии
Когда среда выполнения загружает сборку, она не задает KeyPair свойство . Метод получения свойства полезен только в том случае, если пользователь задал свойство перед использованием AssemblyName объекта для создания динамической сборки, а затем хочет получить пару ключей.
