How could I prompt a line entity from the user?

How could I prompt a "two points" line entity from the user?

Something similar to " Editor.GetPoint() " ??

I was trying to use Editor.GetPoint() method two times. But this option does not show the preview of a line.

I also tried a combination of

doc.SendStringToExecute("line ");

db.ObjectAppended += new ObjectEventHandler(LineAppended);

but this option triggers LineAppended event handler as soon as I create the first point of a line. So it does not help.

Would there be a better way?

Look at the PromptPointOptions. It allows you to specify a Basepoint, and whether to use it, so you get the drag line when picking a second point.
