Question

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会员资料：

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

所以问题出在上面代码示例的最后一行。服务器抛出异常，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？

Server Error in '/' Application.

Answer 1

SimpleMembership，顾名思义，非常简单，并没有实现所有MembershipProvider方法;只是那些MVC基本认证和授权所需的。如果您尝试使用未实现的方法，您将获得该异常。您可以从头开始创建自己的MembershipProvider，也可以从SimpleMembership继承并实现未实现的方法。

更新会员资格。方法不受支持
