Programmatically storing a list into my combobox's item collection

I am working on a Windows Form right now, specifically, a combo box.

Traditionally, one can use/access/define items or strings into the collection through Visual Studio's GUI in the Properties menu. With that said, I would like to do this programatically.

I have two List<string>. Let's say the first List are names, and the second List are ages.

  1. How does one store the entire first List into the collection, so I can use the comboBox to access them?

  2. Upon clicking on an item in this collection, for example, the fifth name, how do I get the index of this item?

So far, I have created my form, and laid the skeleton of the win forms application, but the part of storing the list into the collection is stopping me from moving forward - thank you.

You can try:

for (int i = 0; i < list.count; i++)
{
    combobox.Items.Add(list[i]);
}

And to get the index you could use:

combobox.selectedindex;

I just typed this straight up so use it as a guide more than a copy + paste job :)

For the list of strings it can be done like this

comboBox.DataSource = myList;

If you don't want to tie your list in Datasource, still one line

comboBox.DataSource = myList.ToArray().Clone();

Now, if this is list of Strings you can get the whole string

string s = (string)comboBox.SelectedItem; // vs comboBox.SelectedIndex
