Get Maximum ID of a SharePoint List/Library

I have googled a lot for finding a simple method that will give the maximum ID of a SharePoint list/library. But I have found lots of complex codes and those are also large in lines. I was very astonished that it should be a very simple task. Then I have tried it in my way and it was working:

 private int GetMaxID()

        {

            SPList listName = spWeb.Lists["ListName"];

            int maxID = 0;

            SPListItemCollection listCollection = listName.Items;

            foreach (SPListItem item in listCollection)

            {

                maxID = Convert.ToInt32(item["ID"]);

            }

                

            return maxID;

        }  

It was so simple. Isn't it...........!!
