How to get deserialized xml attribute from dynamic object

Question

I can get the element innertext from expandoobject without any problem. I can't figure out how to get the attribute's value.

By doing Console.WriteLine(obj.Message.Body), I can get the expected string inside the body element.

    private void TestXML()
    {
        string xmlString = @"<?xml version=""1.0"" encoding=""utf-8""?><Message important=""yes"" recevied=""2019-2-12""><Body>Hi there fella!</Body></Message>";
        XDocument doc = XDocument.Parse(xmlString);
        string json = JsonConvert.SerializeXNode(doc);
        dynamic obj = JsonConvert.DeserializeObject<ExpandoObject>(json);

        Console.WriteLine(obj.Message);

    }

I did a debug and and under obj.Message I can see 3 fields:

@important with value "yes"
@received with value "2019-2-12"
Body with value "Hi there fella!"

Is there a way to retrieve the first 2 fields' values with a @ prefix? I have no idea how to deal with this @ character on dynamic objects.

I got it from here: https://stackoverflow.com/questions/13171525/converting-xml-to-a-dynamic-c-sharp-object and for me is the easiest way as I am also working with json format. — Marcus Aurelius, Feb 12 '19 at 03:23

To deal with special characters, such as "@" in dynamic object, you must cast it to ` (IDictionary). And then you can get the recevied attribute as bellow:

var received = ((IDictionary<string, object>)obj.Message)["@recevied"];

This worked. I can successfully get the value. What if I want to return the attribute "recevied" (just realized the spelling mistake), how am I going to do that? – Marcus Aurelius Feb 12 '19 at 06:23
You should check keys in the dictionary to make sure that there is exactly your expected attribute. – Nhan Phan Feb 12 '19 at 06:42

Beat me to it. I used `List keys = new List(((IDictionary)obj.Message).Keys)` Thanks for the help. – Marcus Aurelius Feb 12 '19 at 06:54
