Answer 1

You need to use ComboBox, it has autocomplete

This is simple

Answer 2

WinForms TextBox controls have an AutoComplete property. This behaves the same as the Google TextBox. Here is an example:

Answer 3

Assuming the array is sorted in alphabetical order.

Just handle the TextChanged event for the TextBox and whenever it changes you use ListBox.FindString to find the first item in the ListBox that starts with that string and then call ListBox.TopIndex with the index of that item to make that be the top visible item in the ListBox .
