Декодируйте HTML-тег, чтобы его можно было прочитать, когда он возвращается на сервер, а точнее на контроллер.

Мой движок Aspx.

Как я могу декодировать/кодировать теги html, которые находятся в моем текстовом поле. У меня есть html-тег
, чтобы сделать его более читаемым. Я пробовал ValidationRequest и htmlDecode(freqQuestion.Answer), но не повезло. Я просто продолжаю получать одно и то же сообщение.

Ошибка сервера в приложении «/Администратор».

A potentially dangerous Request.Form value was detected from the client (QuestionAnswer="...ics Phone:

Description: Request Validation has detected a potentially dangerous client input value, and processing of the request has been aborted. This value may indicate an attempt to compromise the security of your application, such as a cross-site scripting attack. To allow pages to override application request validation settings, set the requestValidationMode attribute in the httpRuntime configuration section to requestValidationMode="2.0". Example: . After setting this value, you can then disable request validation by setting validateRequest="false" in the Page directive or in the configuration section. However, it is strongly recommended that your application explicitly check all inputs in this case. For more information, see http://go.microsoft.com/fwlink/?LinkId=153133.
