学习了飞狐兄的程序；使用后发现图形中编组很多时运行速度成几何级别变慢
稍作修改，恳请指正。
///
///查找编组数组,返回实体所在编组数组
///
public List GetGroups(Entity ent)
{
//获得当前文档
Document acDoc = Application.DocumentManager.MdiActiveDocument;
Editor acDocED = acDoc.Editor;
Database acCurDB = acDoc.Database;
List gs = new List();
DBObject Dbobj = (DBObject)ent;
ObjectIdCollection objcol = Dbobj.GetPersistentReactorIds();
using (Transaction acTrans = acCurDB.TransactionManager.StartTransaction())
{
foreach (ObjectId ObjIds in objcol)
{
DBObject Pdbobj = (DBObject)acTrans.GetObject(ObjIds, OpenMode.ForRead, false);
if (Pdbobj.GetType().ToString().Replace("Autodesk.AutoCAD.DatabaseServices.", "") == "Group")
{
Group g = (Group)Pdbobj;
gs.Add(g);
}
}
}
return gs;
}
