Question

Так что я делаю это создание файла Excel с помощью epplus и сохранения его в response.outputstream

По какой-то причине код брейки дает мне ошибку. Я понятия не имею, что я делаю неправильно.

Я получаю эту ошибку

0x800a139e - Microsoft JScript ошибка выполнения: Sys.WebForms.PageRequestManagerParserErrorException: Сообщение, полученные от сервера не может быть проанализирован.

Answer 1

Вы, вероятно, называете это из UpdatePanel или из Ajax-вызова - но что вы делаете, чтобы очистить заголовок ответа и вместо json, чтобы ajax ожидал возврата, вы отправляете что-то другое (вот файл xlsx) - и вы получаете это сообщение, которое не может проанализировать это преимущество.

Ajax или UpdatePanel не могут понять, что вы пытаетесь отправить что-то другое, как этот файл. Вы должны сделать, чтобы создать обработчик эфира, который отправляет этот файл, и помещать его в гиперссылку, эфир удаляет UpdatePanel.
