Way to Deserialize JSON from HttpWebResponse
提问by user1798345
I'm trying to figure out the best way to parse incoming JSON server-side in .NET 3.5. I am receiving "title" from HttpWebResponse in JSON Formate. so i have to retrieve each title and store in the database. so please provide the code for retrieving each title.
我正在尝试找出在 .NET 3.5 中解析传入 JSON 服务器端的最佳方法。我从 HttpWebResponse 以 JSON 格式接收“标题”。所以我必须检索每个标题并存储在数据库中。所以请提供检索每个标题的代码。
public class MyObject
{
public ArrayList list { get; set; }
}
var request = WebRequest.Create("https://api.dailymotion.com/videos?fields=description,thumbnail_medium_url%2Ctitle&search=Good+Morning");
using (var twitpicResponse = (HttpWebResponse)request.GetResponse())
{
using (var reader = new StreamReader(twitpicResponse.GetResponseStream()))
{
JavaScriptSerializer js = new JavaScriptSerializer();
string objText = reader.ReadToEnd();
MyObject myojb = (MyObject)js.Deserialize(objText, typeof(MyObject));
}
}
I am receiving Title in the myojb but how to retrieve Each Title from myojb.
我在 myojb 中收到标题，但如何从 myojb 中检索每个标题。

Serialize into a dynamicobject
序列化为dynamic对象
using (var reader = new StreamReader(twitpicResponse.GetResponseStream()))
{
JavaScriptSerializer js = new JavaScriptSerializer();
var objects = js.Deserialize<dynamic>(reader.ReadToEnd());
foreach (var o in objects)
{
Console.WriteLine(o["title"]);
}
}

Use this piece of code snippet to get Titleby using dynamicobject.
使用这段代码片段来获取Title使用dynamic对象。
.NET 4.0 and above
.NET 4.0 及以上
JavaScriptSerializer js = new JavaScriptSerializer();
var obj = js.Deserialize<dynamic>(reader.ReadToEnd());
foreach (var o in obj["list"])
{
var title = o["title"];
}
.NET 3.5 and below
.NET 3.5 及以下
JavaScriptSerializer js = new JavaScriptSerializer();
var obj = js.Deserialize<Dictionary<string, object>>(reader.ReadToEnd());
foreach (var o in (ArrayList)obj["list"])
{
if (o is Dictionary<string, object>)
var title = (o as Dictionary<string, object>)["title"];
}
Using Linq:
使用 Linq：
JavaScriptSerializer js = new JavaScriptSerializer();
var obj = js.Deserialize<Dictionary<string, object>>(reader.ReadToEnd());
var titles = ((ArrayList)obj["list"]).Cast<Dictionary<string, object>>()
.Select(s => s["title"].ToString()).ToArray<string>();
