Я новый WCF и услужливый сервис. Я изучаю, как передавать объекты в службе WCF.Проходящие объекты в службе WCF
У меня есть код вставки и файл web.config. Я не знаю, почему я вижу эту ошибку.
Пожалуйста, помогите ..
Operation 'saveDataGet' in contract 'IRestServiceImpl' has a query variable named ' param1' of type 'GainSoft.TaskManager.Service.InputData', but type 'GainSoft.TaskManager.Service.InputData' is not convertible by 'QueryStringConverter'. Variables for UriTemplate query values must have types that can be converted by 'QueryStringConverter'.
Description: An unhandled exception occurred during the execution of the current web request.
Please review the stack trace for more information about the error and where it
originated in the code.
