Help With Maze Pathfinding AI.

I have made a level that is more or less a maze. I am trying to make an AI that, when spawned, will navigate through the maze to the player. I have done a lot of research on something like this but i couldn't find anything that would do what i need. I have been working with a*pathfinder project path finding to a static target such as a cube but i can't figure out how to make it follow the character. I use C# so it would be greatly appreciated if all of the scripts were in C#.
