Question

i want to create a property into a dynamic Object, just before it is accessed.
for e.g let’s say, there is an object X. a non existing property “SomeProperty” is accessed on X as follows,

var testProperty = X.SomeProperty;

i want to create X.SomeProperty, while it is accessed.
is it possible in C# dynamics?

Answer 1

public class X : DynamicObject
{
    Dictionary<string, object> dictionary = new Dictionary<string, object>();

    public override bool TryGetMember(
        GetMemberBinder binder, out object result)
    {
        string name = binder.Name.ToLower();

        return dictionary.TryGetValue(name, out result);
    }

    public override bool TrySetMember(SetMemberBinder binder, object value)
    {
        dictionary[binder.Name.ToLower()] = value;
        return true;
    }
}


dynamic obj = new X();
obj.SomeProperty = "Test";
Console.WriteLine(obj.SomeProperty);
