C#子成员中的JSON解析
我试图解析Instagram API中的JSON数据,但在解析子元素时遇到问题。例如,一个Instagram响应如下所示:C#子成员中的JSON解析,c#,json,json.net,C#,Json,Json.net,我试图解析Instagram API中的JSON数据,但在解析子元素时遇到问题。例如,一个Instagram响应如下所示: { "pagination": { "next_url": "https://api.instagram.com/v1/users/273112457/followed-by?access_token=1941825738.97584da.3242609045494207883c900cbbab04b8&cursor=143909084544

}
我的代码如下:
dynamic d = JObject.Parse(response);
foreach (var result in d["data"])
{
string userName = (string)result["username"];
list.Add(userName);
}
foreach (var res in d["pagination"])
{
string nexturl = (string)res["next_url"];
string nextcursor = (string)res["next_cursor"];
}
这一部分工作得很好,但是当我尝试提取分页时,会出现子错误访问错误
我的代码如下:
dynamic d = JObject.Parse(response);
foreach (var result in d["data"])
{
string userName = (string)result["username"];
list.Add(userName);
}
foreach (var res in d["pagination"])
{
string nexturl = (string)res["next_url"];
string nextcursor = (string)res["next_cursor"];
}
如何从C#中的“分页”中提取下一个_url和下一个_curosr?谢谢。与
数据
属性值不同,分页
属性值不是数组,因此不需要foreach
循环:
var res = d["pagination"];
string nexturl = (string)res["next_url"];
string nextcursor = (string)res["next_cursor"];
或者不使用中间变量res
:
string nexturl = (string)d["pagination"]["next_url"];
string nextcursor = (string)d["pagination"]["next_cursor"];
