Another workaround, not beautiful buy workable.

I have an XML file with an element called "MEMDES" with two attribute as "GRADE" and "SPD" to record the RAM module information. There are lot of dupelicate items in SPD.

So here is the code I use to remove the dupelicated items:

        IEnumerable MList =
            from RAMList in PREF.Descendants("MEMDES")
            where (string)RAMList.Attribute("GRADE") == "DDR4"
            select RAMList;

        List sellist = new List();

        foreach (var MEMList in MList)
        {
            sellist.Add((string)MEMList.Attribute("SPD").Value);
        }

        foreach (string slist in sellist.Distinct())
        {
            comboBox1.Items.Add(slist);
        }
