Finding the 'element' from dimension in c#

Im trying to convert one of my Custom node made in python to C#.

Im trying to get the 'element 'which is dimensioned from the dimension element.

if the tag is single tag then I can get the element directly , but if it is multi tag then I have to get the dimension element attached to and then get the rebar element attached to the dimension element.

You can do something like this:

    public static List<ElementId> TaggedRebarsInView(UIDocument uidoc)
    {
        Document doc = uidoc.Document;

        //get rebar tags
        ICollection<Element> fec1 = new FilteredElementCollector(doc, doc.ActiveView.Id).OfCategory(BuiltInCategory.OST_RebarTags).ToElements();
        List<ElementId> taggedRebarIds = new List<ElementId>();
        foreach (IndependentTag tag1 in fec1)
        {
            Element e = tag1.GetTaggedLocalElement();

            //Multirebar tags are attached to a dimension, and wee need to find what rebar the dimension is referencing.
            if (e is Dimension)
            {
                Dimension dim1 = (Dimension)e;
                ReferenceArray ref1 = dim1.References;
                HashSet<ElementId> refIds = new HashSet<ElementId>();
                foreach (Reference r in ref1)
                {
                    refIds.Add(r.ElementId);
                }
                taggedRebarIds.AddRange(refIds.ToList());
            }
            //Add the rebars to a list
            else { taggedRebarIds.Add(tag1.GetTaggedLocalElement().Id); }
        }
        return taggedRebarIds;
    }
