У меня есть проблема с foreach тегами <SimpleField> и <SimpleData>, как я могу их использовать?
Я пытался зациклить его, но он не работает, я использовал sharpKML, потому что код перед использованиемэта библиотека для генерации файла kml
У меня есть код для зацикливания данных из базы данных, чтобы добавить их в XML-файл с помощью SharpKML, и я генерирую его в файл в контроллере
это мой код
