Read values from a Dynamic Object C#

Question

I'm trying to read values from System.Web.Helpers.DynamicJsonObject. I can see the values in the debugger but I can't figure out how to access them. I have tried this

item.GetType().GetProperty("batch_id").GetValue(item, null);

but when I try that I get this response in the debugger "item.GetType().GetProperty("batch_id")' is null"

I have attached a picture from my solution

Thank you, -Tesh

Solution 1

It is dynamic so you can just do:

string batchId = item.batch_id;

If for some reason you have the property name in a string, and don't know it at compile time, the indexing operator will work:

string value = item["batch_id"];

Solution 2

Try enumerating the values DynamicJsonObject.GetDynamicMemberNames Method. It returns an IEnumerable of string.

Solution 3

It doesn't work because they are fields, not properties. And, yeah, it is dynamic, so you can use just item.batch_id.

Thanks driss, that worked perfectly. I'm glad you mentioned the item["batch_id"], because that was my next question :).

Please can you explain in which case property names would be in "string" and in which case as normal properties ?
