在 CreatedUser 事件上填写个人资料会得到：无法为匿名用户设置此 属性。？

Question

我正在尝试用来自用户的数据填充 Profile 属性，就在访问该网站之后。

ASPX:

<form id="form1" runat="server">
<div class="center SignUp">
    <asp:CreateUserWizard ID="CreateUserWizard" runat="server" OnCreatedUser="CreateUserWizard_CreatedUser">
        <WizardSteps>
            <asp:CreateUserWizardStep ID="CreateUserWizardStep1" runat="server">
            </asp:CreateUserWizardStep>
            <asp:CompleteWizardStep ID="CompleteWizardStep1" runat="server">
            </asp:CompleteWizardStep>
        </WizardSteps>
    </asp:CreateUserWizard>
</div>
</form>

代码隐藏：OnCreatedUser 事件

protected void CreateUserWizard_CreatedUser(object sender, EventArgs e)
{
    MembershipUser newUser = System.Web.Security.Membership.GetUser(CreateUserWizard.UserName);
    Profile.UserName = newUser.UserName;     // Get and Set the user name after sign up.
    Guid Id = (Guid)newUser.ProviderUserKey; // Get the UserId after sign up.
    Profile.UserId = Id;                     // Set the UserId after sign up.
}

填写数据后点击"Create User"。我得到：

Server Error in '/' Application.

This property cannot be set for anonymous users.

在 CreateUserWizard_CreatedUser 事件处理程序的开头添加此行：

Profile.Initialize(CreateUserWizard.UserName,true); 这样就变成了：

protected void CreateUserWizard_CreatedUser(object sender, EventArgs e)
{
    if (Page.IsValid)
    {
        Profile.Initialize(CreateUserWizard.UserName,true);
        MembershipUser newUser = System.Web.Security.Membership.GetUser(CreateUserWizard.UserName);
        Profile.UserName = newUser.UserName;     // Get and Set the user name after sign up.
        Guid Id = (Guid)newUser.ProviderUserKey; // Get the UserId after sign up.
        Profile.UserId = Id;                     // Set the UserId after sign up.
    }
}
