Example Version

AssociationDescription Constructor(AssociationType,RowHandle,Int64,RowHandle)
Creates a new utility network AssociationDescription of the specified type. Use this constructor for
Syntax
public AssociationDescription( 
   AssociationType type,
   RowHandle row1,
   long terminalID1,
   RowHandle row2
)

Parameters

type
The association type.
row1
The first row in the association.
terminalID1
The terminal on the first row to connect.
row2
The second row in the association.
Remarks
A utility network connectivity association is defined by two junction rows that are not geometrically coincident. A utility network junction-edge "from side" object connectivity association represents a junction or non-spatial junction object (row1) connecting to the "from" side of a non-spatial edge object (row2). A utility network junction-edge "to side" object connectivity association represents a junction or non-spatial junction object (row1) connecting to the "to" side of a non-spatial edge object (row2).

If type is ArcGIS.Core.Data.UtilityNetwork.AssociationType.Attachment, the overloaded AssociationDescription Constructor(AssociationType,RowHandle,RowHandle) should be used instead.

If type is ArcGIS.Core.Data.UtilityNetwork.AssociationType.Containment, the overloaded AssociationDescription Constructor(AssociationType,RowHandle,RowHandle,Boolean) should be used instead.

If type is ArcGIS.Core.Data.UtilityNetwork.AssociationType.JunctionEdgeObjectConnectivityMidspan, the overloaded AssociationDescription Constructor(AssociationType,RowHandle,RowHandle,Double) should be used instead.
Example
Create utility network features and associations in a single edit operation
// Create an EditOperation
EditOperation editOperation = new EditOperation();
editOperation.Name = "Create pole; create transformer bank; attach transformer bank to pole";

// Create the transformer bank
RowToken transformerBankToken = editOperation.Create(transformerBankLayer, transformerBankAttributes);

// Create a pole
RowToken poleToken = editOperation.Create(poleLayer, poleAttributes);

// Create a structural attachment association between the pole and the transformer bank
RowHandle poleHandle = new RowHandle(poleToken);
RowHandle transformerBankHandle = new RowHandle(transformerBankToken);

AssociationDescription poleAttachment = new AssociationDescription(AssociationType.Attachment, poleHandle, transformerBankHandle);

editOperation.Create(poleAttachment);

// Execute the EditOperation
editOperation.Execute();
