Get and set only public List<> member/field in a class/object

Question

I have an object/class, and I would like to get a list/array of any public List<> members/fields only for it. And at a later point set those members.

currently I can get all the public fields with :

var fieldValues = obj[index].GetType().GetFields(BindingFlags.Instance | BindingFlags.Public);

and a bit of research says I can test GetGenericTypeDefinition() == typeof(List<>), tho I can't test this directly against the values returned in fieldValues.

So in summation, I want to get all the public fields for an object. Sort out the List<>, and set those members.

Thanks for any help provided!

Answer 1

How about something like this,

var fieldValues = test.GetType().GetFields(BindingFlags.Instance | BindingFlags.Public);

foreach(var fieldValue in fieldValues)
{
    if (fieldValue.FieldType.IsGenericType && fieldValue.FieldType.GetGenericTypeDefinition() == typeof(List<>))
    {
        fieldValue.SetValue(test, new List<string>()
        {
            "List Item 1",
            "List Item 2"
        });
    }
}
