How can I read JSON from a file stored locally?

Question

I am attempting to use JSON.Net to load in a JSON file stored locally on an ASP.Net MVC 4 site, but am having trouble pointing to the file. Here is what I am trying to do:

Answer 1

You are passing in the path and filename as your JSON payload. You need to open the file (eg. FileStream) and read the contents into a variable (eg. StreamReader) and pass the file contents as the payload to the deserializer.

Answer 2

You need to read in the JSON first using a FileStream.

Try this.

using(StreamReader sr = new StreamReader(Server.MapPath("~/Content/treatments.json")))
{
      treatments = JsonConvert.DeserializeObject<List<Treatment>>(sr.ReadToEnd());
}
