Hi Wilsoftson,

Basically just call ::web::json::value::parse(...) with a string or a stringstream. Take a look at the documentation for examples.

Thank you stevegates,

by the way, I am a newbie, so I need some detailed answer to help me.

As for my case, I have a file named "data.json". I would like to know how to make a call to this json file and parse it and use the value to my local c++ application.

Kindly looking forward to your reply with some full sample code.

Thank you in advance.....

Hi Wilsoftson,

There are many different ways you can do this. Like I mentioned all you need to do is get the json data into string or a stream. Here is one such example using a std::istream:
    std::ifstream inputStream("json.data", std::ifstream::in);
    ::web::json::value v = ::web::json::value::parse(inputStream);
