使用JSON.NET循环遍历json结果 [英] Loop through json result using JSON.NET

问题描述

我使用下面的代码来获取使用JSON.NET的大厅列表。

I am using below code to get list of halls using JSON.NET.

我想知道如何我可以遍历结果来获取result_name吗？

I want to know how can I loop through the result to get result_name?

这里的代码是示例结果。

here is the code follow by sample result.

var client = new HttpClient();
client.BaseAddress = new Uri("https://www.domain.com/ws/populate_halls_in_location.php");
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
HttpResponseMessage response = await client.GetAsync("https://www.domain.com/ws/populate_halls_in_location.php");

if (response.IsSuccessStatusCode)
{
    var data = await response.Content.ReadAsStringAsync();

    dynamic storydata = JsonConvert.DeserializeObject(data);

    *************************
    *************************
    *************************

    LOOP THROUGH THE RESULT FROM storedata to get hall_name

    *************************
    *************************
    *************************
};

这里是样本输出：

[  
   {  
      "hall_id":1,
      "0":1,
      "site_id":7,
      "1":7,
      "hall_name":"Hall No. 1",
      "is_active":1,
      "3":1
   },
   {  
      "hall_id":2,
      "0":2,
      "site_id":7,
      "1":7,
      "hall_name":"Hall No. 2",
      "is_active":1,
      "3":1
   },
   {  
      "hall_id":3,
      "0":3,
      "site_id":7,
      "1":7,
      "hall_name":"Hall No. 3",
      "is_active":1,
      "3":1
   }
]

推荐答案

这是一个数组，因此
storydata [i] 应该为你提供元素，其中 i = 0..2 。

This is an array, therefore storydata[i] should give you the elements, where i=0..2.

要访问成员，请尝试
dynamic x = storydata [i] [" 1"] 或 int x等表达式=（int）storydata [i] [" 1"] ，它应该给你7。

To access the members, try expressions like dynamic x = storydata[i]["1"] or int x = (int)storydata[i]["1"], which should give you 7.
