A web API need to be created to read from a json file and write output to stream.

What I have tried:

[ApiController]
public class ValuesController : ControllerBase
{
// GET api/values
[HttpGet]
public object Get()
{
string allText = System.IO.File.ReadAllText("/data.json");
object jsonObject = JsonConvert.DeserializeObject(allText);
return jsonObject;
}
}

this only outputs json file..how will i do data streaming.

i have a large json file .reading it in one stretch is time consuming. so the same json should be output using data streaming.

In what format? What are you attempting to do with the data at the other end?

Need more information then ... are you talking SignalR type data streaming? Are you tryping to do this from an app? from a webserver? how big are the files that you're trying to push? can they be zipped and compressed before sending? etc...
