UITypeEditor设置属性的时候，使用了同一个对象

public class CheckedListBoxUITypeEditor : System.Drawing.Design.UITypeEditor
{
    CheckedListBoxUITypeEditor()
    {
        cbx = new CheckedListBox();
    }

    private CheckedListBox _cbx;

    public CheckedListBox cbx
    {
        [MethodImpl(MethodImplOptions.Synchronized)]
        get
        {
            return _cbx;

            }
        }
    }

    private IWindowsFormsEditorService es;

    public new override System.Drawing.Design.UITypeEditorEditStyle GetEditStyle(System.ComponentModel.ITypeDescriptorContext context)
    {
        return System.Drawing.Design.UITypeEditorEditStyle.DropDown;
    }

    public new override bool IsDropDownResizable

    }

    private void bx_Leave(object sender, System.EventArgs e)
    {
        My.Settings.UrlsList.Clear();

        {
            var withBlock = cbx;
            for (int i = 0; i <= withBlock.Items.Count - 1; i++)
            {
                string txt = withBlock.Items(i).ToString;
                string chk = withBlock.GetItemChecked(i).ToString;

                string combined = Strings.LCase(txt) + "," + Strings.LCase(chk);
                if (withBlock.Items(i).ToString != "")
                    My.Settings.UrlsList.Add(combined);
            }
        }

        My.Settings.Save();
    }

    private void LoadListBoxItems()
    {
        ArrayList a = new ArrayList();
        foreach (string s in My.Settings.UrlsList)
            a.Add(Strings.Split(s, ","));

        Hashtable h = new Hashtable();

        for (int i = 0; i <= a.Count - 1; i++)
            h.Add((Array)a.Item(i).GetValue(0).ToString, (Array)a.Item(i).GetValue(1).ToString);
        a = null/* TODO Change to default(_) if this is not a reference type */;

        cbx.Items.Clear();

        foreach (DictionaryEntry de in h)
            cbx.Items.Add(de.Key, System.Convert.ToBoolean(de.Value));
        h = null/* TODO Change to default(_) if this is not a reference type */;
    }
}

如上代码，属性 CheckedListBoxCollectionProperty 和 CheckedListBoxCollectionProperty2 单独是可以使用的，但是，CheckedListBoxCollectionProperty 里变更时，在 CheckedListBoxCollectionProperty2 属性里也变更成和 CheckedListBoxCollectionProperty 一样了。看起来 CheckedListBoxUITypeEditor 只生成了一个对象，被两个属性共用，希望两个属性单独使用自己的 CheckedListBoxUITypeEditor 对象，需要怎么修改呢？
