更新会员资格属性.不支持的方法

Question

我试图研究我现在几个小时获得的例外，但没有进展。

我只是尝试使用以下代码更新会员资料：

MembershipUser user = Membership.GetUser(username);
user.IsApproved = false;
Membership.UpdateUser(user);

因此，问题在上述代码样本中的最后一行。服务器正在抛出一个例外，指出不支持指定的方法。我没有构建错误，我相信我正在使用正确的库。

知道为什么会发生这样的事情？

顾名思义，简单的缩写非常简单，并且没有实现所有成员的方法；只是MVC基本身份验证和授权所需的。如果您尝试使用未实现的方法，则会得到例外。您可以从头开始创建自己的成员Hipprovider，也可以从SimpleMembership继承并实现未实现的方法。
