Adding items in server object-model

Question

How to add a new item to SharePoint list in server object-model using C#.

This is my code and I want to add items using textboxes

        SPWeb web = SPContext.Current.Web;
        SPListItemCollection booksListaItems = web.Lists["Books"].GetItems();
        foreach(SPListItem item in booksListaItems)
        {
            lstItems.Items.Add(item.GetFormattedValue("Title"));
        }

Answer 1

Use this:

SPListItem newItem = lstItems.AddItem();
newItem["Title"] = "New Title"; 
newItem.Update(); 

Once you get a reference to the item, update the columns, then call the Update method to save your changes.
