How to dynamically override all properties of dynamic object?

Question

I have two dynamic objects and I'd want to overwrite values of object A with values of object B

The problem is that both are of type dynamic

I managed to extract names of the properties with

TypeDescriptor.GetProperties(oldObject);

but I'm not sure how can I read & set dynamic property of dynamic object

something like oldObject.GetType().GetProperty("Test") won't work since even GetType().GetProperties() return empty collection

Thanks in advance

Does this answer your question? [How to override get accessor of a dynamic object's property](https://stackoverflow.com/questions/29923280/how-to-override-get-accessor-of-a-dynamic-objects-property) I guess, that you should inherit `DynamicObject` and override its members — Pavel Anikhouski, Jun 15 '20 at 07:26
@PavelAnikhouski Those objects & their classes are external, I'm unable to modify them — Joelty, Jun 15 '20 at 07:36
Although not a satisfying answer, `dynamic` mostly points to a design issue somewhere else. I'd first look at the design reasons for the use of dynamic, before pushing the problem down the road — TheGeneral, Jun 15 '20 at 08:04

Below way you can get all the properties and their values.

dynamic dynamicObj = //define it
object obj = dynamicObj;
string[] propertyNames = obj.GetType().GetProperties().Select(p => p.Name).ToArray();
foreach (var name in propertyNames)
{
    object value = obj.GetType().GetProperty(name).GetValue(obj, null);
}

Use this for private fields.

obj.GetType().GetProperties(BindingFlags.NonPublic);

Unfortunely `propertyNames` is also empty :P damn those dynamics – Joelty Jun 15 '20 at 07:34
then I think you debug and check the dynamic object, does it really have properties? – Vivek Nuna Jun 15 '20 at 07:36
I used your code, with the only difference at `dynamicObj = myDynamicObj` – Joelty Jun 15 '20 at 07:36
Yea, in `Watch Window` I'm able to see it's properties like `myDynamic.Id` = `800` – Joelty Jun 15 '20 at 07:38
Are these properties `public`? – Vivek Nuna Jun 15 '20 at 07:39
Oh, as I see they have no access modifier defined, so they're all private. Btw. Here's pic of how does it look like: https://i.imgur.com/snsTOY6.png – Joelty Jun 15 '20 at 07:48
Its returns all the public properties – Vivek Nuna Jun 15 '20 at 07:50
Unfortunely, the result is the same - empty array of prop names – Joelty Jun 15 '20 at 08:21
