Collision Detection with certain object using CharacterController(C#)

Hi How would I detect collision between a capsule(player) and a block(floor) in C# using a Character Controller instead of a rigid body. Iv been looking around and could Not find anything. I decided to to go To Unity Script References and found this. I have used C# for XNA so I would Like to keep using C# for now. All I would Like to happen is if the capsule is colliding with the block then print out something like "Capsule is colliding". Thanks

Unity Script Reference

     void OnControllerColliderHit(ControllerColliderHit hit) {
         hit.controller.detectCollisions = false;
     }
