DirectoryServices.AccountManagement 扩展 Class WCF 应用程序中的序列化

Question

我有一个 class 我创建的名为 EmployeeData 的继承自 System.DirectoryServices.AccountManagement.UserPrincipal。它允许我使用 .但我现在正在尝试将其移至 WCF Web 服务。有没有办法让我序列化我的 Employee class 即使 UserPrincipal 不可序列化？ IE：只是序列化某些属性或创建不同的架构？我是这个过程的新手，如果这是一个可怕的问题，请原谅我。

对于 WCF，有没有一种方法可以仅在某些属性上使用 DataMember，从而使 UserPrincipal class 不需要可序列化？

根据建议，我停止继承 UserPrincipal 和性别化方法来获取在传入时验证它们的属性。然后我能够使用数据契约属性和数据方法来序列化 class，没有任何问题.
