ListBox items as AutoCompleteCustomSource for a textbox

I have populated some items into a listbox using the datasource property. Now I need to set the AutoCompleteCustomSource for a textBox from the items listed in the listbox. Precisely, the DataSource for the ListBox and the AutoCompleteCustomSource for the textBox are same. How can I set the AutoCompleteCustomSource without using the for-loops?

The AutoCompleteStringCollection takes only string[], so it should be like this:

var cc = new AutoCompleteStringCollection();
cc.AddRange(listBox1.Items.Cast<string>().ToArray());

If your ListBox is a list of strings, you should be able to do this: (untested)

textBox.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
textBox.AutoCompleteSource = AutoCompleteSource.CustomSource;
textBox.AutoCompleteCustomSource.AddRange((List<String>)listBox.DataSource);
