  ISet* anObjectSet
);
[C++]

anObjectSet is a parameter of type ISet

Remarks

The DeleteRelationshipsForObjectSet method is used for removing all relationships in a particular relationship class for the specified set of objects.

This method works in the same way as the DeleteRelationshipsForObject method, except on a set of objects rather than a single one. If a cursor is used to populate the set with objects, ensure that a non-recycling cursor is used.

This method should be called within an edit session.

[C#]

    //e.g., nameOfRelClass="relclass"
    //      nameOfOriginTable="origintable"
    public void IRelationshipClass__DeleteRelationshipsForObjectSet(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();
        IWorkspaceEdit workspaceEdit=(IWorkspaceEdit)workspace;
        workspaceEdit.StartEditing(true);
        workspaceEdit.StartEditOperation();
        relationshipClass.DeleteRelationshipsForObjectSet(objectSet);
        workspaceEdit.StopEditOperation();
        workspaceEdit.StopEditing(true);
        objectSet=null;
    }
