In This Topic
    GetControllerDatasets Method
    In This Topic
    Gets a IReadOnlyList of controller datasets of a specific Dataset type that this table or feature class participates in. This method must be called on the MCT. Use QueuedTask.Run.
    Syntax
    public IReadOnlyList<Dataset> GetControllerDatasets()
    Public Function GetControllerDatasets() As IReadOnlyList(Of Dataset)

    Return Value

    A IReadOnlyList of controller datasets of a specific Dataset type that this table or feature class participates in.
    Exceptions
    ExceptionDescription
    This table does not support controller datasets.
    A geodatabase-related exception has occurred.
    Remarks
    If IsControllerDatasetSupported returns false, calling this method will result in an exception.
    Example
    Get parcel fabric from table
    public static ParcelFabric GetParcelFabricFromTable(Table table)
    {
      ParcelFabric myParcelFabricDataset = null;
      if (table.IsControllerDatasetSupported())
      {
        // Tables can belong to multiple controller datasets, but at most one of them will be a parcel fabric
    
        IReadOnlyList<Dataset> controllerDatasets = table.GetControllerDatasets();
        foreach (Dataset controllerDataset in controllerDatasets)
        {
          if (controllerDataset is ParcelFabric)
          {
            myParcelFabricDataset = controllerDataset as ParcelFabric;
          }
          else
          {
            controllerDataset.Dispose();
          }
        }
      }
      return myParcelFabricDataset;
    }
    Get a Utility Network from a Table
    public static UtilityNetwork GetUtilityNetworkFromTable(Table table)
    {
      UtilityNetwork utilityNetwork = null;
    
      if (table.IsControllerDatasetSupported())
      {
        // Tables can belong to multiple controller datasets, but at most one of them will be a UtilityNetwork
        IReadOnlyList<Dataset> controllerDatasets = table.GetControllerDatasets();

          {

            controllerDataset.Dispose();
          }
        }
      }
      return utilityNetwork;
    }
    Get a Utility Network from a Layer
    // This routine obtains a utility network from a FeatureLayer, SubtypeGroupLayer, or UtilityNetworkLayer
    public static UtilityNetwork GetUtilityNetworkFromLayer(Layer layer)
    {
      UtilityNetwork utilityNetwork = null;
    
      if (layer is UtilityNetworkLayer)
      {
        UtilityNetworkLayer utilityNetworkLayer = layer as UtilityNetworkLayer;
        utilityNetwork = utilityNetworkLayer.GetUtilityNetwork();
      }
    
      else if (layer is SubtypeGroupLayer)
      {
        CompositeLayer compositeLayer = layer as CompositeLayer;
        utilityNetwork = GetUtilityNetworkFromLayer(compositeLayer.Layers.First());
      }
    
      else if (layer is FeatureLayer)
      {
        FeatureLayer featureLayer = layer as FeatureLayer;
        using (FeatureClass featureClass = featureLayer.GetFeatureClass())
        {
          if (featureClass.IsControllerDatasetSupported())
          {
            IReadOnlyList<Dataset> controllerDatasets = new List<Dataset>();
            controllerDatasets = featureClass.GetControllerDatasets();
            foreach (Dataset controllerDataset in controllerDatasets)
            {
              if (controllerDataset is UtilityNetwork)
              {
                utilityNetwork = controllerDataset as UtilityNetwork;
              }
              else
              {
                controllerDataset.Dispose();
              }
            }
          }
        }
      }
