Sharepoint Object model

Sharepoint Object model

To programmatically deal with your Sharepoint services or officer server you need to
add the references Microsoft.Office.Server or Microsoft.Sharepoint to your
project.
You can find this references under
C:\Program Files\Common Files\microsoft shared\Web Server Extensions\12\ISAPI

Sharepoint Website Collection.

Listing all the websites from the share point site and its owner.

SPSite site = new SPSite("http://localhost");
SPWeb web=site.AllWebs;
foreach(SPWeb web in collection)
        {
            DropDownList1.Items.Add(web.Author.ToString());
        }

Listing all lists in the website
SPSite site = new SPSite("http://localhost/SiteDirectory/IT"); //IT-site name
        SPWeb web = site.OpenWeb();
        SPList list = web.Lists["Posts"]; // a List in the site
        foreach(SPListItem col in list.Items)
        {
            DropDownList2.Items.Add(col.Title.ToString()); // Item in the List
        }
