For loop doesn't work as expected

Hello everybody, I am currently trying to create a recursive function, but i found out that it isn't working and i dont really understand why this happens or how i could fix it. I use the following function: public AIMove RecursiveMiniMaxAI(int Depth, int MaxDepth, gamestate StateOfBoard, int Player) { //Some general code if (Player == 2) { for (int i = 0; i < MoveList.Count; i++) //foreach (int i in MoveList) { //Some code //Recursive function ReturnMove = RecursiveMiniMaxAI(Depth + 1, MaxDepth, AIStates[Depth + 1, j], 1); //Some code } } else { for (int k = 0; k < MoveList.Count; k++) //foreach (int k in MoveList) { //Some code //Recursive function call ReturnMove = RecursiveMiniMaxAI(Depth + 1, MaxDepth, AIStates[Depth + 1, j], 2); //Some code } } //Some code return ReturnMove; } The problem is that both for loops only loop once. Even if i or k are 3,4 or 5, the loop runs once for i =0 and then doesn't loop again. This happens with both the for statement and the foreach statement. If i remove the recursive function call, the loop runs just fine, so it must have something to do with that. I would be really happy if anyone could point me in the right direction. PS. i already posted this topic in the Artificial Intelligence forum, but since this doesn't really concern AI anymore I als posted it here. For reference, here is the link to my older post with my complete code in it. http://www.gamedev.net/topic/622037-connect-four-ai/

All right, this is the point where i feel relieved but stupid

I finally got the code to work and also realised which mistakes i made:

1. When using the "foreach int k in MoveList" statement, i failed to adapt MoveList[k] to k, which makes sure the program goes in an endless loop.

2. I somehow overlooked the fact that the for loop was indeed connecting when debugging, I really don't understand it since i checked it a few dozen times before posting here, but in the end it appeared to work and since i didnt change anything in my code, i really must have overlooked it.

Anyhow, i got the code working and also fixed another mistake which caused the bad results to appear. Thank you very much again for helping me learn!

Now on to the next problem, which should be easier to solve. My girlfriend hates the fact that the stones in my Connect Four game just appear instead of falling down nicely, so i will try to fix that now
