看起來你的返回類型可能有問題。試試這個：

// 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; 
     } 
    }
