How would you guys go about looping through an arraylist, and erasing indexes based on an if statement. I'm drawing a blank on how to do it. Everytime you erase the length is smaller and the stack is dropped down an index.

For example:

ArrayList Gartfeild = new ArrayList();

Gartfeild.Push(1);
Gartfeild.Push(2);
Gartfeild.Push(1);
Gartfeild.Push(3);
Gartfeild.Push(1);

//ArrayList 0 - 4  = {1,2,1,3,1}

for(int i; i < Gartfeild.Length; i++)
{
	if(Gartfeild.Get(i) == 1)
	{
		Gartfeild.Erase(i);
	}
}

Start the loop from the back

Also you shouldn't use functions inside loop's condition check.
You can replace it with:

int iLength = Gartfeild.Length;
for (int i = 0; i < iLength; i++)

or even with

for (int i = 0, iLength = Gartfeild.Length; i < iLength; i++)

And in your case, as 8guawong said, you can do backward iteration:

for (int i = Gartfeild.Length - 1; i >= 0; i--)
