JSON字符串转换为对象的C＃列表（字符串来自请求为NULL） [英] convert json string to c# list of objects (string comes from request as NULL)

问题描述

我有以下的code到JSON字符串转换成列表中的对象：

I have the following code to convert json string to list of objects:

        public class rest_all
        {
            public string restaurants { get; set; } 
        }


        public class rest_all_data
        {
            public string RestaurantName { get; set; }
            public string CategoryName { get; set; }
            public string FourSquareID { get; set; } 
        }


        public class rest_collection 
        {
            public IEnumerable<rest_all_data> rest_all_data { get; set; }
        }

和这里的主要功能是：

public void AddRestaurantMultiple (rest_all rest_all)
        {
            JavaScriptSerializer serializer = new JavaScriptSerializer();
            rest_collection collection = serializer.Deserialize<rest_collection>(rest_all.restaurants);
        }

问题是，当我提出一个JSON字符串像这样的HTTP请求：

the problem is that when I make an http request with a json string like this:

{"restaurants" : [{"RestaurantName":"a","CategoryName":"b","FourSquareID":"c"},{"RestaurantName":"d","CategoryName":"e","FourSquareID":"f"}]

它总是给我空的 AddRestaurantMultiple 函数...它是什么我做错了？

it always gives me null at the AddRestaurantMultiple function...what is it am i doing wrong??

推荐答案

您模式应该是

public class Restaurant
{
    public string RestaurantName { get; set; }
    public string CategoryName { get; set; }
    public string FourSquareID { get; set; }
}

public class rest_collection
{
    public List<Restaurant> restaurants { get; set; }
}

---

var result = new JavaScriptSerializer().Deserialize<rest_collection>(yourjson);
