如何覆盖Silvelright 4 RIA服务的AuthenticationService User.IsInRole [英] How to override Silvelright 4 RIA Service AuthenticationService User.IsInRole

问题描述

我已经开始了与Silverlight 4的导航应用程序模板（启用RIA服务）。 （因为我真的不喜欢臃肿的商务应用模板）
我已经添加了一种验证服务，我能够对用户进行认证，
但是想覆盖User.IsInRole方法。

I've started out with the Silverlight 4 Navigation Application template (RIA Services enabled). (As I really don't like the bloated Business Application Template) I've added an Authentication Service and I'm able to authenticate users, but want to override the User.IsInRole method.

WebContext.Current.User.IsInRole("Guest");

但我找不到任何地方重写的行为。

But I cannot find any place to override the behaviour.

推荐答案

你到底想干什么？ User.IsInRole是IPrincipal.IsInRole的实现，真的不应该被忽略。

What are you trying to do? User.IsInRole is an implementation of IPrincipal.IsInRole and really shouldn't be overridden.

如果你想设置的用户角色，你可以做到这一点通过overridding的GetAuthenticatedUser或GetAnonymousUser方法在你的AuthenticationService服务器上。

If you want to set the user roles, you can do it on the server in your AuthenticationService by overridding the GetAuthenticatedUser or GetAnonymousUser methods.

如果你想类似于IsInRole方法，你可以在客户端上的部分类扩展的用户类型，并添加任何方法才有意义。

If you want a method similar to IsInRole, you can extend the User type with a partial class on the client and add whatever methods make sense.
