 SPSiteDataQuery query = new SPSiteDataQuery();

 query.Lists = "<Lists ServerTemplate=\"301\" />";

query.ViewFields = "<ProjectProperty Name=\"Title\" />";

 DataTable dt = new DataTable();
                dt = web.GetSiteData(query);

                foreach (DataRow row in dt.Rows)
                {
                    string a = row["ProjectProperty.Title"].ToString();

                 }
