dynamic JContainer (JSON.NET) & Iterate over properties at runtime
提问by Alex
I'm receiving a JSON string in a MVC4/.NET4 WebApi controller action. The action's parameter is dynamicbecause I don't know anything on the receiving end about the JSON object I'm receiving.
我在 MVC4/.NET4 WebApi 控制器操作中收到一个 JSON 字符串。动作的参数是dynamic因为我对接收端的 JSON 对象一无所知。
public dynamic Post(dynamic myobject)
The JSON is automatically parsed and the resulting dynamicobject is a Newtonsoft.Json.Linq.JContainer. I can, as expected, evaluate properties at runtime, so if the JSON contained something like myobject.myproperty then I can now take the dynamic object received and call myobject.mypropertywithin the C# code. So far so good.
JSON 会自动解析，结果dynamic对象是Newtonsoft.Json.Linq.JContainer. 正如预期的那样，我可以在运行时评估属性，因此如果 JSON 包含类似 myobject.myproperty 的内容，那么我现在可以获取接收到的动态对象并myobject.myproperty在 C# 代码中调用。到现在为止还挺好。
Now I want to iterate over all properties that were supplied as part of the JSON, including nested properties. However, if I do myobject.GetType().GetProperties()it only returns properties of Newtonsoft.Json.Linq.JContainerinstead of the properties I'm looking for (that were part of the JSON).
现在我想遍历作为 JSON 一部分提供的所有属性，包括嵌套属性。但是，如果我这样做，myobject.GetType().GetProperties()它只会返回 的属性Newtonsoft.Json.Linq.JContainer而不是我正在寻找的属性（这是 JSON 的一部分）。
Any idea how to do this?
知道如何做到这一点吗？

I think this can be a starting point
我认为这可以作为一个起点
dynamic dynObj = JsonConvert.DeserializeObject("{a:1,b:2}");
//JContainer is the base class
var jObj = (JObject)dynObj;
foreach (JToken token in jObj.Children())
{
if (token is JProperty)
{
var prop = token as JProperty;
Console.WriteLine("{0}={1}", prop.Name, prop.Value);
}
}
EDIT
编辑
this also may help you
这也可以帮助你
var dict = JsonConvert.DeserializeObject<Dictionary<string, object>>(jObj.ToString());
