            {
                var DisplayFileName = Request.Form.Files[0];

                string DirectoryCreate = myValue1 + "\\"  + fileName;
                string exportPath = myValue2 + "\\"  + fileName;

                if (!Directory.Exists(DirectoryCreate))
                {
                    Directory.CreateDirectory(DirectoryCreate);

                }

                if (DisplayFileName.Length > 0)
                {
                    var filedata = ContentDispositionHeaderValue.Parse(Request.Form.Files[0].ContentDisposition).FileName.Trim('"');
                    var dbPath = Path.Combine(DirectoryCreate, fileName);

                    using (var stream = new FileStream(dbPath, FileMode.Create))
                    {
                        Request.Form.Files[0].CopyTo(stream);
                    }

                        if (exportPath != "")
                        {
                           ex.DownloadOutPut(exportPath);
                        }


                    }
                    return Ok(new { dbPath });
                }
                else
                {
                    return BadRequest();
                }
            }

            {
                return StatusCode(500, $"Internal server error: {ex}");
            }
        }
  public FileStreamResult DownloadOutPut(string path)
        {


                var filename = System.IO.Path.GetFileName(path);
                var mimeType = "application/octet-stream";
                var stream = System.IO.File.OpenRead(path);


            return new FileStreamResult(stream, mimeType) { FileDownloadName = filename };

angular 7 client side

public uploadFile = (files) => {
    if (files.length === 0) {
      return;
    }

    let fileToUpload = files[0];
    const formData = new FormData();
    formData.append('file', fileToUpload, fileToUpload.name);

    this.http.post('https://localhost:44396/api/ApprovalQuality/', formData, {reportProgress: true, observe: 'events'})
      .subscribe(event => {
        if (event.type === HttpEventType.UploadProgress)
        {
          this.progress = Math.round(100 * event.loaded / event.total);
        }
        else if (event.type === HttpEventType.Response) {
          this.message = 'Upload success.';
          this.onUploadFinished.emit(event.body);
        }
      });
