Linq with DynamicObject

I have a list where MyType: DynamicObject. The reason for MyType inheriting from DynamicObject is because I need a type that can contain an unknown amount of properties.

Everything works fine until I need to filter the List. Is there a way to make linq that will do something like this:

return all items where any of the properties is empty string or white space?

Well, if all the properties of the object are not internally unknown to yourself, you can do it.

, DynamicObject, , , GetDynamicMemberNames(), nuget ImpromptuInterface .

return allItems.Where(x=> Impromptu.GetMemberNames(x, dynamicOnly:true)
                       .Any(y=>String.IsNullOrWhiteSpace(Impromptu.InvokeGet(x,y));

, MyType, , .

return allItems.Where(x => x.MyValues.Any(y=>String.IsNullOrWhitespace(x));

( ) linq ?

, ExpandoObject:

var list = new List<ExpandoObject>();
dynamic e1 = new ExpandoObject();
e1.a = null;
e1.b = "";
dynamic e2 = new ExpandoObject();
e2.x = "xxx";
e2.y = 123;
list.Add(e1);
list.Add(e2);
var res = list.Where(
    item => item.Any(p => p.Value == null || (p.Value is string && string.IsNullOrEmpty((string)p.Value)))
);

ExpandoObject , , , .
