I use DashStyle.Custom define dash,the code like this:
DiagramLink link = d.Factory.CreateDiagramLink(root2, root);
            link.Pen.DashStyle = DashStyle.Custom;
            link.Pen.DashPattern = new float[] { 1f, 1f };
            link.Pen.Width = 0.2f;
when I export visio , the dash link can not show ,I think the dash link can not be finded in visio .
How I should define the DashPattern to export visio?

thank you for your reply!
