    Example
    Get a list of Network Diagrams with inconsistent ConsistencyState
    public List<NetworkDiagram> GetInconsistentDiagrams(UtilityNetwork utilityNetwork)
    {
      // Get the DiagramManager from the utility network
    
      using (DiagramManager diagramManager = utilityNetwork.GetDiagramManager())

        List<NetworkDiagram> myList = new List<NetworkDiagram>();
    
        // Loop through the network diagrams in the diagram manager
    
        foreach (NetworkDiagram diagram in diagramManager.GetNetworkDiagrams())
        {
          NetworkDiagramInfo diagramInfo = diagram.GetDiagramInfo();
    
          // If the diagram is not a system diagram and is in an inconsistent state, add it to our list
    
          if (!diagramInfo.IsSystem && diagram.GetConsistencyState() != NetworkDiagramConsistencyState.DiagramIsConsistent)
          {
            myList.Add(diagram);
          }

          {

    Editing Network Diagram
    public void EditDiagram(NetworkDiagram diagram, List<Guid> globalIDs)
    {
      //     These routines generate their own editing transaction, and therefore cannot be wrapped
      //     in a separate transaction. Because the editing performed by these routines cannot
      //     be undone, thise routines can also not be called within an editing session. All
      //     edits in the current edit session must be saved or discarded before calling these
      //     routines.
    
      // refresh the diagram - synchronizes it based on the latest network topology
      diagram.Update();
    
      // append features to the diagram
      diagram.Append(globalIDs);
    
      // overite the diagram with a set of features 
      diagram.Overwrite(globalIDs);
    
      NetworkDiagramInfo info = diagram.GetDiagramInfo();
      if (info.CanExtend)
      {
        diagram.Extend(NetworkDiagramExtendType.ExtendByContainment);
    
        // or extend for only a set of utility network globalIDs
        diagram.Extend(NetworkDiagramExtendType.ExtendByContainment, globalIDs);
      }
      // delete a diagran
      diagram.Delete();
    }
