Examples

The following example adds new SalesOrderHeader entities to the Contact entity. Then it gets all related ends from the Contact entity and displays relationship name, source role name, and target role name for each related end.

using (AdventureWorksEntities context =
    new AdventureWorksEntities())
{
    Contact contact = new Contact();

    // Create a new SalesOrderHeader.
    SalesOrderHeader newSalesOrder1 = new SalesOrderHeader();
    // Add SalesOrderHeader to the Contact.
    contact.SalesOrderHeaders.Add(newSalesOrder1);

    // Create another SalesOrderHeader.
    SalesOrderHeader newSalesOrder2 = new SalesOrderHeader();
    // Add SalesOrderHeader to the Contact.
    contact.SalesOrderHeaders.Add(newSalesOrder2);

    // Get all related ends
    IEnumerable<IRelatedEnd> relEnds =
        ((IEntityWithRelationships)contact).RelationshipManager
        .GetAllRelatedEnds();

    foreach (IRelatedEnd relEnd in relEnds)
    {
        Console.WriteLine("Relationship Name: {0}", relEnd.RelationshipName);
        Console.WriteLine("Source Role Name: {0}", relEnd.SourceRoleName);
        Console.WriteLine("Target Role Name: {0}", relEnd.TargetRoleName);
    }
}
