ArcGIS Pro 3.1 API Reference Guide
ArcGIS.Core.Data.NetworkDiagrams Namespace / DiagramManager Class / GetNetworkDiagrams Method / GetNetworkDiagrams(Envelope) Method
The extent ArcGIS.Core.Geometry.Envelope of interest where to search for overlapping network diagrams.
Example

In This Topic
    GetNetworkDiagrams(Envelope) Method
    In This Topic
    Gets the list of NetworkDiagrams which overlap with the specified extent. This method must be called on the MCT. Use QueuedTask.Run.
    Syntax
    Public Overloads Function GetNetworkDiagrams( _
       ByVal extentOfInterest As Envelope _
    ) As IReadOnlyList(Of NetworkDiagram)

    Parameters

    extentOfInterest
    The extent ArcGIS.Core.Geometry.Envelope of interest where to search for overlapping network diagrams.

    Return Value

    A list of NetworkDiagrams.
    Exceptions
    ExceptionDescription
    A geodatabase-related exception has occurred. For example, the diagram manager is invalid.
    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);
    }
    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);
          }
          else
          {
            diagram.Dispose(); // If we are not returning it we need to Dispose it
          }
        }
    
        return myList;
      }
    }
