以下示例向 实体添加新 SalesOrderHeader 实体 Contact 。 然后，它从 Contact 实体获取所有相关端，并显示每个相关端的关系名称、源角色名称和目标角色名称。

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);
    }
}
