Be-58 pilot reported that during rotation a single engine cessna was on approach 100 feet above him ...

Narrative:

I taxied to runway 03 for departure (IFR). The tower was closed. I verified on ground [control] 'tower closed'. Someone in the tower answered 'tower closed'. I taxied to runway 03 (calm wind runway) for departure notifying tower and CTAF. After setting up waypoints in the GPS arranging charts and rwys I radioed 'beech xxxxx departing 03 - straight out'. As I heard nothing from other traffic I commenced takeoff 2 minutes prior tower opening. Just at the point of rotation; I saw a cessna single coming the opposite direction at approximately 100 feet above me. I was not sure if I could abort safely. I flew about 20 feet off the runway until the cessna was overhead. Then I continued about 20 feet above until the end of the runway. Then I began a slow climb. I then heard 'aircraft over 21 at ZZZ 1 - are you on frequency?' at that point I switched to approach for my IFR clearance to ZZZ 2. My aircraft is TCAS equipped nothing came up on TCAS on runways or takeoff roll. If the cessna had a xpdr in operation; my TCAS would have called traffic.P.south. When the tower called 'aircraft over 21 are you on frequency?' I felt it was for the other aircraft since I departed 03. Also they (tower) knew I was on frequency.

Title: BE-58 pilot reported that during rotation a single engine Cessna was on approach 100 feet above him coming in the opposite direction.

Narrative: I taxied to RWY 03 for departure (IFR). The Tower was closed. I verified on ground [control] 'Tower Closed'. Someone in the Tower answered 'Tower closed'. I taxied to RWY 03 (calm wind RWY) for departure notifying Tower and CTAF. After setting up waypoints in the GPS arranging charts and RWYs I radioed 'Beech XXXXX departing 03 - straight out'. As I heard nothing from other traffic I commenced takeoff 2 minutes prior Tower opening. Just at the point of rotation; I saw a Cessna single coming the opposite direction at approximately 100 feet above me. I was not sure if I could abort safely. I flew about 20 feet off the runway until the Cessna was overhead. Then I continued about 20 feet above until the end of the runway. Then I began a slow climb. I then heard 'aircraft over 21 at ZZZ 1 - are you on frequency?' At that point I switched to approach for my IFR clearance to ZZZ 2.
