         Parser Error Message: Type 'System.Web.UI.WebControls.CreateUserWizard' does
           not have a public property named 'LayoutTemplate'.

        Source Error:


            Line 6:  <asp:Content ID="BodyContent" runat="server"

    </WizardSteps>
</asp:CreateUserWizard>

我如何从形式上解决这个错误？

Answer 1

LayoutTemplate从4.0版开始提供。如果您从代码中注释掉代码中的相应行，您应该能够成功编译它。

编辑：我注意到您的代码不包含安全问题和答案字段的声明，这会导致抛出异常。您可以添加必需的字段，如MSDN上的code sample版本3.5所示。
