HRESULT GetObjectsRelatedToObjectSet(
  ISet* anObjectSet,
  ISet** relatedObjectSet
);
[C++]

Remarks

The GetObjectsRelatedToObjectSet  method returns a set of objects that are related to the objects contained by the anObjectSet parameter. It behaves the same as GetObjectsRelatedToObject, except that it accepts a set of objects as a parameter.

If multiple objects in the input set are related to a common object, that object will only be included once in the returned set.

If the input set is constructed with a cursor, ensure that a non-recycling cursor is used.

[C#]

    //e.g., nameOfRelClass="relclass"
    //      nameOfOriginTable="origintable"
    public void IRelationshipClass__GetObjectsRelatedToObjectSet(IWorkspace workspace, string nameOfRelClass, string nameOfOriginTable)
    {
        IFeatureWorkspace featureWorkspace=(IFeatureWorkspace)workspace;
        IRelationshipClass relationshipClass=featureWorkspace.OpenRelationshipClass(nameOfRelClass);
        ITable originTable=featureWorkspace.OpenTable(nameOfOriginTable);
        ESRI.ArcGIS.esriSystem.ISet objectSet=new ESRI.ArcGIS.esriSystem.SetClass();
        objectSet.Add(originTable.GetRow(1));
        objectSet.Add(originTable.GetRow(2));
        objectSet.Add(originTable.GetRow(3));
        objectSet.Reset();
        ESRI.ArcGIS.esriSystem.ISet resultSet=relationshipClass.GetObjectsRelatedToObjectSet(objectSet);
        objectSet=null;
    }
