我收到错误：

错误1名称空间'LocalGarageFinder.Membership'中不存在类型或命名空间名称'CreateUser'（您是否缺少程序集引用？）

我检查过命名空间。全押.Security.Web.Security;缺什么？请帮忙

}

Answer 1

你在这里发生了一个命名空间冲突。我想你正试图通过调用Membership.CreateUser来访问asp.net会员提供者，但它找不到它，因为它只是在你的LocalGarageFinder.Membership命名空间中查找。

如果您无法将名称空间更改为更容易使用的名称空间，则可以使用其完整名称空间将您的调用前缀添加到成员资格提供程序。

这会将您的电话更改为：

MembershipUser newUser = System.Web.Security.Membership.CreateUser(Username.Text, Password.Text, Email.Text, passwordQuestion, SecurityAnswer.Text, true, out createStatus);

Answer 2

试试MembershipUser newUser = System.Web.Security.Membership.CreateUser(...)。似乎编译器正在查看LocalGarageFinder.Membership，其中确实没有CreateUser类型。

ASP.net C＃。 Membership.CreateUser方法 - 缺少引用或汇编。堆叠
