Question

I have a stack in which certain array of strings is pushed.when I want to pop the stack I need to remove the topmost element(the last element that was in) and pop the rest….

if (simpleStack.Count > 0)
{
    simpleStack.Peek().Remove(0);
    string open = simpleStack.Pop();

    PopulateListView(open);
    complicatedStack.Push(open);
}

I’m trying to peek the element and remove but it doesn’t seems to work.

Not sure what the issue is – pop the first item. That will remove it from the stack.

Then you can pop the remaining items.

if (simpleStack.Count > 0)
{
    simpleStack.Pop(); // remove top item, discarding it
    string open = simpleStack.Pop(); // Fails if stack has only 1 element

    PopulateListView(open);
    complicatedStack.Push(open);
}
