更新会员资产。 方法不受支持
我试图研究我现在几个小时没有进展的例外情况。
我只是尝试使用以下代码更新成员资格配置文件：
MembershipUser user = Membership.GetUser(username); user.IsApproved = false; Membership.UpdateUser(user); 所以问题在于上面代码示例中的最后一行。 服务器抛出exception，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。
知道为什么会出现这样的事情吗？

顾名思义，SimpleMembership非常简单，并没有实现所有MembershipProvider方法; 只是MVC基本身份validation和授权所需的那些。 如果您尝试使用未实现的方法，您将获得该exception。 您可以从头开始创建自己的MembershipProvider，也可以从SimpleMembershipinheritance并实现未实现的方法。
