PromptPointOptions的问题求助

<p><strong>我想通过下列语句</strong></p><p><strong>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Editor ed = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.Editor;<br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; PromptPointOptions ppo = new PromptPointOptions("指定插入点\n:");<br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; double x = ed.GetPoint(ppo).Value.X;<br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; double y = ed.GetPoint(ppo).Value.Y; </strong></p><p><strong>获取指定点的X值和Y值。</strong></p><p><strong>但是出现个问题，就是要点2次才能获得X,Y的值，我试过单独获取X值把double y = ed.GetPoint(ppo).Value.Y; 去掉，就只需点一下了。</strong></p><p><strong>有什么办法可以让我只点一下 就获取2个值？</strong></p>
