INetworkDataset.Attribute Property

Network dataset attribute by index.

Public Function get_Attribute ( _
    ByVal Index As Integer _
) As INetworkAttribute

public INetworkAttribute get_Attribute (
    int Index
);

Remarks

Returns the attribute at the specified index. The indexes go from 0 to AttributeCount -1.

INetworkDataset.AttributeByID Property

Network dataset attribute corresponding to the specified ID.

Public Function get_AttributeByID ( _
    ByVal ID As Integer _
) As INetworkAttribute

public INetworkAttribute get_AttributeByID (
    int ID
);

INetworkDataset.AttributeByName Property

Network dataset attribute corresponding to the specified name.

Public Function get_AttributeByName ( _
    ByVal Name As String _
) As INetworkAttribute

public INetworkAttribute get_AttributeByName (
    string Name
);

Remarks

The AttributeByName property will return a reference to the attribute with the specified name. Attribute names are not case sensitive.

INetworkDataset.AttributeCount Property

Number of attributes in the network dataset.

Public ReadOnly Property AttributeCount As Integer

public int AttributeCount {get;}

Remarks

Returns the number of attributes assigned to the network dataset.

INetworkDataset.Buildable Property

Indicates if this network dataset is buildable.

Public ReadOnly Property Buildable As Boolean

public bool Buildable {get;}

Remarks

Returns a boolean value indicating if the network dataset can be built using the INetworkBuild:BuildNetwork method. This method will return true for Geodatabase and Shapefile network datasets. Use the INetworkDataset:NetworkType property to determine the type of network dataset.

INetworkDataset.DirtyArea Property

The dirty area polygon of the network dataset.

Public Function get_DirtyArea ( _
    ByVal Location As IPolygon _
) As IPolygon

public IPolygon get_DirtyArea (
    IPolygon Location
);

INetworkDataset.NetworkType Property

The type of the network dataset.

Public ReadOnly Property NetworkType As esriNetworkDatasetType

public esriNetworkDatasetType NetworkType {get;}

Remarks

Returns the type of network dataset; geodatabase, shapefile, SDC or unknown. Use this property to handle properties that differ based on the type of network dataset.

SDC networks are no longer supported so you should never see that value.

INetworkDataset.Source Property

Network dataset source by index.

Public Function get_Source ( _
    ByVal Index As Integer _
) As INetworkSource

public INetworkSource get_Source (
    int Index
);

Remarks

Returns the source at the specified index. The indexes go from 0 to SourceCount -1.

INetworkDataset.SourceByID Property

Network dataset source corresponding to the specified ID.

Public Function get_SourceByID ( _
    ByVal ID As Integer _
) As INetworkSource

public INetworkSource get_SourceByID (
    int ID
);

Remarks

Returns the source with the specified ID. The ID is not equal to the index. Rather it is the internal ID of the source as stored in the metadata tables. It can be retrieved from the INetworkSource::ID property.

INetworkDataset.SourceByName Property

Network dataset source corresponding to the specified name.

Public Function get_SourceByName ( _
    ByVal Name As String _
) As INetworkSource

public INetworkSource get_SourceByName (
    string Name
);

Remarks

The SourceByName property will return a reference to the source with the specified name. Source names are not case sensitive. For ArcSDE Geodatabases, both the fully qualified name and unqualified name can be used to return topologies.

INetworkDataset.SourceCount Property

Number of sources in the network dataset.

Public ReadOnly Property SourceCount As Integer

public int SourceCount {get;}

Remarks

Returns the number of sources in the network dataset.

INetworkDataset.State Property

Indicates whether the network dataset is built or not.

Public ReadOnly Property State As esriNetworkDatasetState

public esriNetworkDatasetState State {get;}

Remarks

The State property indicates the current status of the network dataset; whether the network dataset is unbuilt, built or empty. Network analysis may be performed on unbuilt network datasets, but the results cannot be guaranteed to be correct and will depend on the edits that have been made.

INetworkDataset.SupportsTurns Property

Indicates if this network dataset supports network turn elements.

Public ReadOnly Property SupportsTurns As Boolean

public bool SupportsTurns {get;}

Description

Returns a boolean value indicating if the network dataset supports turns. For shapefile and geodatabase networks, this property is set on the IDENetworkDataset interface of the data element.

Once a network dataset is created, turn support cannot be added. This can only be specified when the network is created.

Classes that implement INetworkDataset

Classes	Description

Remarks

A NetworkDataset is a collection of feature classes that participate in a network relationship. Each feature class has a topological role in the network and a network may have multiple feature classes in the same role. A feature dataset may have multiple networks but a feature class can only belong to one network, either a network dataset or geometric network. A Feature class in the network dataset is called a network source. Network datasets may also have attributes which are used for solving against a network dataset. Network dataset sources can also participate within an ITopology

The IDatasetContainer2 interface should be used for creating and opening network datasets. The INetworkBuild interface should be used for adding or removing sources or attributes from a network dataset and for building a network dataset.
