   [HttpPost("UploadSingleFile"), Route("[action]")]
    public async Task UploadSingleFile([FromForm(Name = "file")] IFormFile file)
    {


        // Process uploaded files

        string folderName = "Uploads";
        string webRootPath = hostingEnvironment.WebRootPath;
        string newPath = Path.Combine(webRootPath, folderName);
        if (!Directory.Exists(newPath))
        {
            Directory.CreateDirectory(newPath);
        }

        Repository.Models.File fileModel = new Repository.Models.File();
        fileModel.Name = ContentDispositionHeaderValue.Parse(file.ContentDisposition).FileName.Trim('"');
        fileModel.Path = $"{folderName}/{file.FileName}";
        fileModel.Size = file.Length;
        fileModel.Type = file.ContentType;

        string fullPath = Path.Combine(newPath, fileModel.Name);

        fileModel.Extension = Path.GetExtension(fullPath);
        fileModel.CreatedDate = Utility.Common.GetDate;
        fileModel.CreatedBy = 1;

        //fileModel save to db

        using (var stream = new FileStream(fullPath, FileMode.Create))
        {
            //file.CopyTo(stream);
            await file.CopyToAsync(stream);
        }

        return Ok(new { count = 1, path = filePath });
    }
