如何检测ExpandoObject与动态对象？

Question

How to I determine if a Type is an ExpandoObject vs a Dynamic object?

This is returning true for both:

public static bool IsDynamicObject(Type type)
{
    return typeof(IDynamicMetaObjectProvider).IsAssignableFrom(type);
}

Example Code for Dynamic Object:

public class Entity
{
    public Guid Id { get; set; }
    public String Name { get; set; }
}

Delta<Entity> x = new Delta<Entity>();
dynamic dynamicX = x;
dynamicX.Name = nameof(Entity);
dynamicX.Id = typeof(Entity).GUID;

Example Code for Expando Object:

dynamic childX = new ExpandoObject();
childX.A = 1;

The ExpandoObject can be casted to a dictionary to get the member names and values

public static bool IsExpandoObject(object objectValue)
{
    if (objectValue == null)
        return false;

    if (IsDynamicObject(objectValue.GetType()))
    {
        IDictionary<string, object> expandoPropertyValues = objectValue as IDictionary<string, object>;
        return expandoPropertyValues != null;
    }

    return false;
}

public static bool IsDynamicObject(Type type)
{
    return typeof(IDynamicMetaObjectProvider).IsAssignableFrom(type);
}
