Question

I want to do a foreach loop while taking out members of that foreach loop, but that’s throwing errors. My only idea is to create another list inside of this loop to find which Slices to remove, and loop through the new list to remove items from Pizza.

foreach(var Slice in Pizza)
{
    if(Slice.Flavor == "Sausage")
    {
        Me.Eat(Slice); //This removes an item from the list: "Pizza"
    }
}

Answer 1

You can do this, by far the simplest way I have found (like to think I invented it, sure that’s not true though ;))

foreach (var Slice in Pizza.ToArray())
{
    if (Slice.Flavor == "Sausage") // each to their own.. would have gone for BBQ
    {
        Me.Eat(Slice);
    }
}

..because it’s iterating over a fixed copy of the loop. It will iterate all items, even if they are removed.

Handy isn’t it!

(By the way guys, this is a handy way of iterating through a copy of a collection, with thread safety, and removing the time an object is locked: Lock, get the ToArray() copy, release the lock, then iterate)

Hope that helps!
