You can find it in 2007 ;-). Here is a sample for 2006.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Entity tmpEnt = (Entity)myT.GetObject(entid, OpenMode.ForRead);
//highlight the entity
ObjectId[] ids = new ObjectId[1];
ids[0] = entid;
SubentityId index = new SubentityId(SubentityType.Edge, 0);
FullSubentityPath path = new FullSubentityPath(ids, index);
tmpEnt.Highlight(path, true);
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
