如何从Twitter获取每日趋势？

Question

我想问问，如果有人知道如何提取出“名称”和“查询”，并可能将其存储在数组列表中。

源文件：https://api.twitter.com/1/trends/daily.json

Answer 1

基于这样一个问题：Parse JSON in C#

让代表你提取JSON类，并从该JSONHelper类使用的代码从JSON中提取类链接的问题：

public class JSONHelper 
{ 
    public static T Deserialise<T>(string json) 
    { 
     T obj = Activator.CreateInstance<T>(); 
     MemoryStream ms = new MemoryStream(Encoding.Unicode.GetBytes(json)); 
     DataContractJsonSerializer serialiser = new DataContractJsonSerializer(obj.GetType()); 
     ms.Close(); 
     return obj; 
    } 
} 

Answer 2

您可以使用JObject，像： -

string response = requestData("https://api.twitter.com/1/trends/daily.json"); 
JObject jsonResponse = new JObject(); 
var name = string.Empty; 
var query = string.Empty; 
try 
{ 
     jsonResponse = JObject.Parse(response); 
     name = (string)jsonResponse["name"]; 
     query = (string)jsonRespone["query"]; 
} 
catch 
{ 
     return ""; 
} 

public string requestData(string url) 
{ 
    HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url); 
    HttpWebResponse resp = (HttpWebResponse)req.GetResponse(); 

    StreamReader sr = new StreamReader(resp.GetResponseStream()); 
    string results = sr.ReadToEnd(); 
    sr.Close(); 

    return results; 
}
