我检查了命名空间。所有英寸Security.Web.Security;什么不见​​了？请帮助

Answer 1

尝试MembershipUser newUser = System.Web.Security.Membership.CreateUser(...)。看起来编译器正在寻找LocalGarageFinder.Membership，其中确实没有CreateUser类型。

Answer 2

你已经遇到了命名空间冲突。 我想你想访问与您的来电Membership.CreateUser的asp.net成员资格提供程序，但它无法找到，因为它只是看着你的LocalGarageFinder.Membership命名空间。

如果你不能改变你的命名空间的东西有点更容易使用，你可以前缀你与它的完整的命名空间的成员资格提供电话。

这将您的电话更改为：

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