WHY SAYS ME THAT IS AN ERROR?

I have been watching burgzerg arcade tutorial #17 :http://www.youtube.com/watch?v=xBELb3ollhQ&list=SPE5C2870574BF4B06 and i make exactly that he wanted to do, but the console is saying to me error CS0542: `Skill.Skill()': member names cannot be the same as their enclosing type and in the video he puts the script exactly like me but he hasn´t got the error, PLEASE CHECK MY SCRIPT TO SEE WHY I HAVE THE ERROR.

public class Skill : ModifiedStat { private bool _known;

 public void Skill() {
     _known= false;
     ExpToLevel = 25;
     LevelModifier = 1.1f;
 }
 
 public bool Known {
     get{ return _known; }
     set{ _known = value; }
 }

}

public enum PoderName { Melee_Offence, Melee_Defence, Ranged_Offence, Range_Defence, Magic_Offence, Magic_Defence, }
