.Net Core Web API - uploading multiple files. Postman returns empty Json.

[TheBugSlayer]

Hello,

Have written code to upload multiple files through one zip file and it works. In Postman I am able to download the zip file. However, I am trying to implement an alternative solution where the files are added to a multipart content then to the response. The code works...but in Postman I receive an OK status but the body of the response is empty.

Please help me figure out what I am missing or doing wrong. Thank you.

C# CODE

[HttpGet("/results2/{resultcount}")]
public ActionResult GetFiles(int results)
{
var fi = ReadFiles(results);

if (fi.Count() > 0)
{
var content = new MultipartContent();


var objectContent = new StringContent(Newtonsoft.Json.JsonConvert.SerializeObject(fi.Select(f => f.FullName)));
content.Add(objectContent);

foreach (FileInfo f in fi)
{
var fileContent = new StreamContent(new FileStream(f.FullName, FileMode.Open));
fileContent.Headers.ContentType = System.Net.Http.Headers.MediaTypeHeaderValue.Parse("text/plain");
fileContent.Headers.ContentDisposition = new System.Net.Http.Headers.ContentDispositionHeaderValue("attachment");
content.Add(fileContent);
}

var response = new HttpResponseMessage();
response.Content = content;
return Ok(response);
}
else
return BadRequest("Number of files must be greater than zero (0)!");
}
