Declaration

Source position: classesh.inc line 864

public property TStringList.Duplicates : TDuplicates read FDuplicates write FDuplicates;

Duplicates describes what to do in case a duplicate value is added to the list:

dupIgnore	Duplicate values will not be added to the list, but no error will be triggered.
dupError	If an attempt is made to add a duplicate value to the list, an EStringListError exception is raised.
dupAccept	Duplicate values can be added to the list.

If the stringlist is not sorted, the Duplicates setting is ignored.
