Hello. Who knows, tell me how to display createdby in the vknet library.
the date and the text of the post itself are displayed, but the name of the publisher is not.

var wallsearch = vk.Wall.Search(new WallSearchParams

            {
                Fields=GroupsFields.All,
                OwnerId= -118780401,
                Query = searchstring,
                Extended = true,
                Count=1
              

            });

            foreach (var items in wallsearch.WallPosts)
            {

                {

                    checkedListBox4.Items.Add(items.CreatedBy + "---" + items.Date + "---" + items.Text);
                }
            }

the output is like this:

and before the date, there should also be the name of the publisher.

Answer 1

var item = $"{items.CreatedBy}---{items.Date}---{items.Text}";
// put debug point here
checkedListBox4.Items.Add(item);
