Get Origin and destination feature class names from relationship class

RoobeshModi — Thu, 19 Jan 2012 17:28:07 GMT

Hi,

I was trying to find the Origin featureclass name and the Destination feature class name programatically through vb.net but could not see while implementing Irelationshipclass Interface to get the Feature class name.

We could find the property which specifies the alias name but one cannot reach to the feature class using alias name.

Please suggest how to fetch the information.

Thanks,
Roobesh

the origin and destination featureclass are returned of type IFeatureclass interface but they are a FeatureClass class. You need to cast the IFeatureClass to an IDataset which has the name property.

Thanks!!

How do I cast so that I get the Featureclass name related to my other featureclass though relationship class.

Well assuming you have the relationship class object, the IRelationshipClass.OriginClass property is an IFeatureclass that you cast to IDataset. The syntax depends on your language of choice.

VB.NET
dim originDataset as IDataset = DirectCast(relClass.OriginClass, IDataset)
dim name as string = originDataset.Name

C#
IDataset originDataset = (IDataset)relClass.OriginClass
string name = originDataset.Name
