流参数始终为空

Question

I am sending post request from my client (ASP.NET MVC) to a webapi service, however, the webapi service controller needs a Stream parameter which is always null .

Request from ASP.NET MVC app:

using(var client = new HttpClient())
{
    Token token = GetToken();
    client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue(token.TokenType, token.AccessToken);
    var content = new StreamContent(stream);
    content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
    content.Headers.ContentDisposition = new ContentDispositionHeaderValue("form-data") { Name = "keliaStream" };
    var res = client.PostAsync(GetSdcUri(), content).Result;
}

WebApi Controller:

// POST: api/Publication
[HttpPost]
[Route("whatever-route")]
[RequireHttps]
public System.Web.Mvc.ActionResult GenerateSDCFromTBox([FromBody]Stream keliaStream)
{
    // whatever
}

keliaStream is always null, what am I missing?

Thanks to your comments, I've been able to find a solution.
In case anyone struggles with the same problem here is my solution :

Client (ASP.NET MVC) :

using(var client = new HttpClient())
{
    Token token = GetToken();
    client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue(token.TokenType, token.AccessToken);
    var content = new StreamContent(stream);
    content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
    var res = client.PostAsync(GetSdcUri(), content).Result;
}

SERVEUR (WebApi) :

public System.Web.Mvc.ActionResult GenerateSDCFromTBox()
{
    Stream stream = Request.Content.ReadAsStreamAsync().Result;
    // return do what ever with stream
}
