How do I retrieve text from an item displayed in a ComboBox?

I am using Delphi 10.3, and need to retrieve the Text from a ComboBox. The ComboBox was loaded earlier via:

for PLCIndex := 0 to numDoorPLCs - 1 do
begin
if (tmpDoorMng.returnDoorPLCController(tmpDoorPLC,PLCIndex)) then
begin
plc_name := tmpDoorPLC.get_Comm.get_name;
cbDoorPLC.Items.Add(plc_name);
end;
end;

When the user later selects an item from the ComboBox, I need to get the text for that item. How is it done?

You get the index of the current selected item and then access it through Items property.

If you're adding plain primitive types then just cast to the data type, but if it's a data structure you'd have to cast to the data structure type.

I am using primitive types and am trying to retrieve data from the ComboBox after loading it earlier in the program.

SelectedPLCStr is defined as a String.
I tried the following two statements, and neither one worked.
SelectedPLCStr := cbDoorPLC.GetItemIndex.Text;
SelectedPLCStr := cbDoorPLC.ItemIndex.Text;
