You populate combo boxes by setting their DataSource property (see here for more details on what you can bind to them).

To do this you'll need to expose the list first, so put it into a property. This is how the form will access it, after creating a new instance of the class.

public string[] TransactionCodes
{
    get { return strTransactionCodes; }
    set { strTransactionCodes = value; }
}

Then do this on the FormLoad event

eg

private void Form1_Load(object sender, EventArgs e)
{
    TansactionCode trans = new TansactionCode();    // Create new instance
    combobox.DataSource = trans.TransactionCodes;   // Access the list property
}
