Example

In This Topic
    GetNetworkDiagram Method (DiagramManager)
    In This Topic
    Retrieves the NetworkDiagram with the specified name. This method must be called on the MCT. Use QueuedTask.Run.
    Syntax
    public NetworkDiagram GetNetworkDiagram( 
       string name
    )
    Public Function GetNetworkDiagram( _
       ByVal name As String _
    ) As NetworkDiagram

    Parameters

    name
    The name of the network diagram.

    Return Value

    The NetworkDiagram with the specified name.
    Exceptions
    ExceptionDescription
    A geodatabase-related exception has occurred.
    This method or property must be called within the lambda passed to QueuedTask.Run
    Example
    Get Network Diagrams
    using (DiagramManager diagramManager = utilityNetwork.GetDiagramManager())
    {
      // get all the diagrams
      IReadOnlyList<NetworkDiagram> diagrams = diagramManager.GetNetworkDiagrams();
    
      // get a diagram by name
      NetworkDiagram diagram = diagramManager.GetNetworkDiagram(diagrameName);
    
      // get diagrams by extent
      diagrams = diagramManager.GetNetworkDiagrams(extentOfInterest);
    
      // get diagrams from a set of utility network feature GlobalIDs
      diagrams = diagramManager.GetNetworkDiagrams(globalIDs);
    
      // get diagrams from a set of utility network feature GlobalIDs within an extent
      diagrams = diagramManager.GetNetworkDiagrams(extentOfInterest, globalIDs);
    }
    Change the Layout of a Network Diagram
    public void DiagramElementQueryResultAndNetworkDiagramSubsetClasses(Geodatabase geodatabase, DiagramManager diagramManager, string diagramName)
    {
      // Retrieve a diagram
      using (NetworkDiagram diagramTest = diagramManager.GetNetworkDiagram(diagramName))
      {
        // Create a DiagramElementQueryByElementTypes query object to get the diagram elements we want to work with
        DiagramElementQueryByElementTypes query = new DiagramElementQueryByElementTypes();
        query.QueryDiagramJunctionElement = true;
        query.QueryDiagramEdgeElement = true;
        query.QueryDiagramContainerElement = true;
    
        // Retrieve those diagram elements
        DiagramElementQueryResult elements = diagramTest.QueryDiagramElements(query);
    
        // Create a NetworkDiagramSubset object to edit this set of diagram elements
        NetworkDiagramSubset subset = new NetworkDiagramSubset();
        subset.DiagramJunctionElements = elements.DiagramJunctionElements;
        subset.DiagramEdgeElements = elements.DiagramEdgeElements;
        subset.DiagramContainerElements = elements.DiagramContainerElements;
    
        // Edit the shapes of the diagram elements - left as an exercise for the student
        TranslateDiagramElements(subset);
    
        // Save the new layout of the diagram elements
        diagramTest.SaveLayout(subset, true);
      }
    }
