How to edit an Item in Code Behind (Sitecore v6.5) – 5

Sitecore will throw exception when editing an item if the item is not in editing mode. 
There are two ways where you can put an item in editing mode.
1.       Sitecore.Data.Items.ItemEditing
2.       Sitecore.Data.Items.EditContext
To begin editing
Using(new Sitecore.Data.Items.EditContext(item))
To Commit/End Changes
If previous statement passes, automatically item changes will be committed.
To Cancel Edit
If previous statement fails, automatically item changes will be rolled back.
1.       Sitecore.Data.Items.ItemEditing
Unless and until, we call EndEdit() or CancelEdit(), Sitecore does not commit the changes.
            //Getting Master Database
            Sitecore.Data.Database masterDB = Sitecore.Configuration.Factory.GetDatabase("master");
            //Getting a Sitecore Item
            Sitecore.Data.Items.Item home = masterDB.GetItem("/sitecore/content/Home");
            //Begin Editing Sitecore Item
                home["Title"] = "Title from Code";
                //Commit the changes
            catch (Exception)
                //Revert the Changes
2.       Sitecore.Data.Items.EditContext
Closure of Using in EditContext will implicitly commit any changes within that segment of code and also calls dispose().
            //Getting Master Database
            Sitecore.Data.Database masterDB = Sitecore.Configuration.Factory.GetDatabase("master");
            //Getting a Sitecore Item
            Sitecore.Data.Items.Item home = masterDB.GetItem("/sitecore/content/Home");
            //Using EditContext to edit an Item
            using (new Sitecore.Data.Items.EditContext(home))
                home["Text"] = "Modified Text from Code";
