IBaseNetwork Interface

Provides access to members that specify the properties of a base network.


Name Description
Read-only property AssociationsTable Returns the associations table.
Method CreateQuery Creates query object.
Method CreateTracer Creates tracer.
Read-only property DiagramDataset Returns the diagram dataset of the utility network.
Read-only property DirtyAreaTable Returns the dirty area table.
Read-only property ScaleDelta Returns the scale delta.
Read-only property SearchTolerance Returns the search tolerance.

IBaseNetwork.AssociationsTable Property

IBaseNetwork.DirtyAreaTable Property

Returns the dirty area table.

Public ReadOnly Property DirtyAreaTable As ITable
public ITable DirtyAreaTable {get;}
// Get Utility Network from the helper method

Dataset unDataset = GetUNDatasetFromYourHelperMethod()

IWorkspace workspace = (IWorkspace)unDataset.Workspace;

// Get all the dirty areas

IBaseNetwork baseNetwork = (IBaseNetwork)unDataset;

ITable dirtyAreaTable = baseNetwork.DirtyAreaTable;

// Get dirty table's fields

string shapeFieldName = ((IFeatureClass)dirtyAreaTable).ShapeFieldName;

int areaFieldIndex = dirtyAreaTable.FindField(shapeFieldName);

int creatorFieldIndex = dirtyAreaTable.FindField("CREATOR");

IBaseNetwork.ScaleDelta Property
