动态对象的列名

Question

How can I get the header (columns Name) of a dynamic List ?

here is my code

  var Participants = Newtonsoft.Json.JsonConvert.DeserializeObject<List<dynamic>>(obj.ToString());  

and I need to get the name of all the column inside the var Participants

Any ideas ?

Use Newtonsoft.Json.Linq.JProperty , take for example you have the following json object:

{ "summary" : { "123": {}, "456": {} } }

You want to deserialize to a list of the following:

class SomeClass {
  public string ID {get;set;}
}

Your code would be:

dynamic responseDynamic = Newtonsoft.Json.JsonConvert.DeserializeObject(json);

List<SomeClass> someList = new List<SomeClass>();

foreach (var item in responseDynamic.summary)
{
    string id = ((Newtonsoft.Json.Linq.JProperty)item).Name;

    someList.Add(new SomeClass(){ID = id});
}
