您的退货类型似乎有问题。试试这个：

    // changed result type to JsonResult
    public JsonResult UploadUiLogo()
    {
        try
        {
            if (Request.Files != null)
            {
                foreach (string file in Request.Files)
                {
                    HttpPostedFileBase hpf = Request.Files[file] as HttpPostedFileBase;

                    if (hpf.ContentLength == 0)
                        continue;
                    string savedFileName = Path.Combine(Server.MapPath("~/Content/uploadlogo"), Path.GetFileName(Guid.NewGuid() + hpf.FileName));
                    hpf.SaveAs(savedFileName);

                    //create a c# object rather than writing the string
                    var result = new { name = savedFileName };
                    //json result return
                    return Json(result);
                }
            }

            return null;
        }
        catch (Exception ex)
        {
            throw ex;
        }
    }
