Using SPContext Class

SPContext class is used to return context information about the current Web application, site collection, site, list, or a list item.

SPList myCurrentList = SPContext.Current.List;
SPWeb myWeb = SPContext.Current.Web;
SPSite mySite = SPContext.Current.Site;
SPWebApplication myCurrentWebApp = SPContext.Current.Site.WebApplication;

To return the top-level web site of the current site collection:
SPWeb myTopLevelSite = SPContext.Current.Site.RootWeb;

To return the current list item:
SPListItem myCurrentItem = (SPListItem)SPContext.Current.Item;

Opening a web in the current site collection and  returning the current user:
using(SPWeb myWeb = SPContext.Current.Site.OpenWeb(GUID Web))
    SPUser currentUser = SPContext.Current.Web.CurrentUser;

Using SPContext you can also obtain a reference to any web other than the current one. The following code returns the context of any specified site:
SPWeb myWeb = SPContext.Current.Site.AllWebs["AnyOtherSite"];

Hope this helps–

    Quick tip, you can get the current context SPListItem without the cast: SPContext.Current.ListItem will return it.
