Unable to send files to ASP.NET WEB API using HttpClient

Question

I need to send file to WEB API using HttpClient and using the below code to achieve it. I couldn't figure out why am not revcieving any files in WEB API, but the request hits the APIcontroller.

Client Side Code

            var fs = new FileStream(@"C:\SomLocation\ExcelFile.xlsx", FileMode.Open, FileAccess.Read);
            MemoryStream ms = new MemoryStream();
            fs.CopyTo(ms);
            var client = new HttpClient();                
            client.BaseAddress = new Uri(GetAPIBaseAddress());
            HttpContent content = new StreamContent(ms);
            var data = new MultipartFormDataContent();  
            data.Add(content, "file1");
            var response = client.PostAsync(GetImportAPIURL(), data).Result;

In API

       System.Web.HttpFileCollection hfc = System.Web.HttpContext.Current.Request.Files;
       foreach(System.Web.HttpPostedFile file in hfc)
       {
           // do some processing;
       }

Any help would be greatly appreciated.

you better send it as a byte array instead of MultipartFormDataContent — Frebin Francis, Jul 21 '16 at 11:23
@FrebinFrancis - I tried sending it as ByteArrayContent but still it is of no use. — Unknown, Jul 21 '16 at 11:33
instead of byte array content you can create a model and create a property with datatype byte[] and post value into that byte array — Frebin Francis, Jul 21 '16 at 11:34
or if you want to use the current method then refer this link https://dotnetcodr.com/2013/01/10/how-to-post-a-multipart-http-message-to-a-web-service-in-c-and-handle-it-with-java/ — Frebin Francis, Jul 21 '16 at 11:36
