Using an Array for a combobox datasource

I am working on a program where the user will update combobox entries. What I want to do is update an entry in an array which then updates the entry in the combobox. Because the order of the combobox must not change I believe this is the best way to do this.

However, I have been unable to find much information about linking an array as a datasource to a combobox.

Is this possible if so what is the best way to do so? Is there a better way to do what I want?
