Site Architecture Object Model:All Site Architecture objects and collections are available in the “Microsoft.SharePoint” namespace.

1.        Site Collection: This collection of sites is known as “Site Collection”.

SPSite object can be instantiated by following methods

·   SPSite objSPSite = new SPSite("Site URL");

·   SPSiteCollection objSiteCollection = objWebApplication.Sites;

int index = 0;

SPSite objSite = objSiteCollection[index];

2.    Sub Sites: Each SharePoint website is represented by SPWeb object whether it is a top level website or a sub site. SPWeb object has a Webs property that returns a collection of other SPWeb objects

  SPWeb object can be instantiated by following methods

 a.        SPSite objSPSite = new SPSite("Site  URL");

SPWeb myWeb = objSPSite.OpenWeb();

3.                 3.  List(Each SPList object has members that are used to manage the list or access items in the list)

                            SPList myList = myWeb.Lists["My First List"];

4.                 4.  Fields: Each SPField object has members that contain settings for the field

         SPList mylist = myweb.Lists.TryGetList("Announcements");

                                               SPField fld = mylist.Fields[SPBuiltInFieldId.Expires];

5.                5.  List Item: Represents a single row in the list

          SPList myList = myWeb.Lists["My First List"];

                                               SPListItem myListItem = myList.Items[5];
