The selection set contains the entitys in the order selected.
For instance these lines were drawn left to right and selected right to left.
The enames in the selection set are numbered highest to lowest, demonstrating that the selection order is retained in the selection set.

Perhaps you could demonstrate this with some .NET code

Sometimes the question is more important than the answer.

afterthought:
What is the total number of objects you are selecting ?
Would you be better served making some single selections ??

Thank you very much! I had thought that the order in the selection set is random before.
What I want to do is that according to the select order by the user,give the lines some proper Identifier.
