How can I check a players inventory for an item, get the amount of that item in that inventory and remove a certain amount of it from that inventory?

////Check if player has item///// 

private bool CanRemoveResource(Player player, string resource, int amount)
        {
            // Check player's inventory
            var inventory = player.CurrentCharacter.Entity.GetContainerOfType(CollectionTypes.Inventory);

            // Check how much the player has
            var foundAmount = 0;
            foreach (var item in inventory.Contents.Where(item => item != null))
            {
                if (item.Name == resource)
                {
                    foundAmount = foundAmount + item.StackAmount;
                }
            }

            if (foundAmount >= amount) return true;
            return false;
        }

/////removing items from player/////
public void RemoveItemsFromInventory(Player player, string resource, int amount)
        {
            ItemCollection inventory = player.GetInventory().Contents;

            int removeAmount = 0;
            int amountRemaining = amount;

            foreach (InvGameItemStack item in inventory.Where(item => item != null))
            {
                if (item.Name != resource) continue;

                removeAmount = amountRemaining;
                if (item.StackAmount < removeAmount) removeAmount = item.StackAmount;
                inventory.SplitItem(item, removeAmount);
                amountRemaining = amountRemaining - removeAmount;
            }
        }​
