Here you are confused between List<T> and item in the List<T>, Lets clear the confusion first.

List : Represents a strongly typed list of objects

T : The type of elements in the list i.e item in the List

In your case, List<Barang> is a list and Barang is type of element.

List<Barang> barangnya = new List<Barang> ();

Above line creates instance of List<Barang>, now you can add elements to it, here element will be instance of your Barang class.

Here is the code to add new element to your List.

barangnya.Add(new Barang() {IdBarang = 10, NamaBarang = "Prasad", HargaBarang = 6299857});

Your question is a little unclear, but this is one of the ways to create and add something into the list:

 //creating a list
 List<Barang> barangnya = new List<Barang>();

 //adding items to list
 barangnya.Add(new Barang {IdBarang = 1, NamaBarang = "Buku Tulis", HargaBarang = 5000});

[EDIT] When you insert something into the List, it doesn't become a list. It is just a member of it.

[EDIT n.2] You can refer to the members like this:

//getting the value of the member
var firstBarangInList = barangnya[0];

//changing a member's attribute
barangnya[1].NamaBarang = "New name";

//removing member from list
barangnya.RemoveAt(3);
