В итоге я просто передал информацию на веб-сервер с помощью сценария PHP.
Приведенные выше варианты просто не сработали для моей ситуации.
Вот суть.У меня есть некоторый код с индикаторами выполнения и различными проверками и обработчиками, не связанными с простой отправкой файла, но я уверен, что вы можете выбрать его.Я удалил свой код аутентификации как из C #, так и из PHP, но при необходимости не должно быть слишком сложно свернуть свой собственный.
в C #:
/*
* Here's the short+sweet about how I'm doing this
* 1) Copy the file from mobile device to web server by querying PHP script with paramaters for each line
* 2) PHP script checks 1) If we got the whole data file 2) If this is a duplicate data file
* 3) If it is a duplicate, or we didn't get the whole thing, it goes away. The mobile
* device will hang on to it's data file in the first case (if it's duplicate it deletes it)
* to be tried again later
* 4) The server will then process the data files using a scheduled task/cron job at an appropriate time
