我有一个 CreateUserWizard 供用户注册新帐户。
我添加了我的文本字段和必填字段验证器
但是，当我使用空用户名单击注册按钮时，出现错误：
异常详细信息：System.ArgumentException：成员的用户名必须不同于空字符串
参数名称：登录名
用户名字段有它的 requiredfieldvalidator 所以它应该可以工作。我还添加了
用户名RequiredErrorMessage
属性给向导，但它没有任何区别。
上面错误信息中提到的loginName是 LoginView 的一个控件。我在同一页面上有这个，但在注册 CreateUserWizard 期间没有使用它。
为什么会这样？

在后面的代码中：

{
string email = cuwRegister.UserName;
string username = cuwRegister.UserName;
string password = cuwRegister.Password;
Page.Validate("CreateUserWizard");
if(Page.IsValid)
CreateUser(email, username, password);
}

Login lwPanelLogin = (Login)lwLogin.FindControl("lwLoginPanel");
if (lwPanelLogin != null)
{

lwPanelLogin.UserNameLabelText = "Email";
}
}
protected void CreateUser(string email, string username, string password)
{
bool isLoggedIn = System.Web.HttpContext.Current.User.Identity.IsAuthenticated;
if (Membership.GetUserNameByEmail(email) == null)
{
MembershipUser member = Membership.CreateUser("aaa", password, email);
}
if(!isLoggedIn)
if (System.Web.Security.Membership.ValidateUser(username, password))
{
FormsAuthentication.SetAuthCookie(username, true);
}
}
（请注意，我使用用户名字段获取电子邮件，然后使用电子邮件登录）
