如何调用多个参数? [英] How to call multiple parameters?

问题描述

我正在尝试调用querystring-data/name = key& price = 77，但它给了我一个空白数组.我是否需要在数据控制器类中添加一些内容才能使此查询正常工作?

Hi,

I am trying to call querystring -- data/name=key&price=77, but its giving me an blank array. Do I need to add something in the data controller class to make this query work?

	//User class
	public IQueryable <database_ab> getData(Query query)
        {
            var data = db.database_ab.AsQueryable();
 
            if (query.name != null)
            {
                data = data.Where(c => c.Name == query.name);
            }
 
            if (query.price != null)
            {
                data = data.Where(c => c.Price == query.price);
            }
 
            return data;
        }

		
////////////////////////////////////////////////////////////////////////////////


       //Data controller
      public HttpResponseMessage getData([FromUri] Query query)
        {
            User layer = new User();
           // if (User.IsInRole("user"))
           // {
            var result = layer.getData(query);

                if (result == null)
                {
                    // return HttpResponseMessage
                    var message = string.Format("No data was found");
                    return Request.CreateErrorResponse(HttpStatusCode.NotFound, message);
                }
                return Request.CreateResponse(HttpStatusCode.OK, result);
           // }
        }

任何帮助深表感谢.非常感谢.
