如何做过滤操作
PromptSelectionResult ProSset = null;
TypedValue[] filList = new TypedValue[1] { new TypedValue((int)DxfCode.LayerName, name) };
SelectionFilter sfilter = new SelectionFilter(filList);
Editor ed = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.Editor;
ProSset = ed.SelectAll(sfilter);
ProSset Status为e为Error，Value为null
求解决方案
