How to get all connections which are not in location box?
for example:

ArrayList ConnArrList = new ArrayList;
SelectionSet set = new SelectionSet();
Eplan.EplApi.DataModel.Project currentProject = set.GetCurrentProject(false);
Eplan.EplApi.DataModel.Page[] selectedPages = set.GetSelectedPages();
foreach (Eplan.EplApi.DataModel.Page page in oSelectionSet.GetSelectedPages())
{
　　DMObjectsFinder dmf = new DMObjectsFinder(oProject);
　  ConnectionsFilter oConnF = new ConnectionsFilter();
    oConnF.Page = page;
    Connection[] arrConn = dmf.GetConnections(oConnF);
　　 foreach (var conn in arrConn)
　　 {
　　　　if(conn.Properties.CONNECTION_FULLLOCATION_AUTOMATIC!=conn.page.Properties.DESTINATION_LOCATION)
　　　　{
　　　　　　ConnArrList.Add(conn);
       }
     }
}
