#c# #razor
Вопрос:
Сейчас я разрабатываю текстовый редактор razor base, все, что я хочу сделать, это один раз прочитать данные CSV, использовать эти данные в следующем посте. Это будет означать создание глобальных переменных после открытия страницы, используйте эти переменные в полном объеме исходного кода программирования. Я пытался это сделать, однако мне нужна перезагрузка csv-файлов после публикации, Как я могу использовать один раз для чтения csv-данных (списка) по всему миру, как это.

Ответ №1:
измените общедоступный список doc1 = новый список(); на общедоступный статический список doc1 = новый список(); решена проблема.
