JContainer、JObject、JToken 和 Linq 混淆

一篇关于 JContainer、JObject、JToken 和 Linq 的文章，并添加案例代码。文章分为引言、JContainer、JObject、JToken 和 Linq 的介绍、案例代码和部分。

csharp
JObject person = new JObject();
person["name"] = "John";
person["age"] = 25;
person["city"] = "New York";
Console.WriteLine(person.ToString());

{
  "name": "John",
  "age": 25,
  "city": "New York"
}

csharp
string json = @"{
  'name': 'John',
  'age': 25,
  'city': 'New York'
}";
JToken person = JToken.Parse(json);
Console.WriteLine(person["name"]);
Console.WriteLine(person["age"].ToObject());

John

csharp
JObject data = JObject.Parse(json);
var adults = from p in data["people"]
             where (int)p["age"] >= 18
             select p;
foreach (var adult in adults)
{
    Console.WriteLine(adult["name"]);
}
