Question

我有以下代码：

        if (Membership.FindUsersByName(username) == null)
        {
            Membership.CreateUser(username, password, email);
        }

        if (!Roles.RoleExists("USR"))
        {
            Roles.CreateRole("USR");
        }
        Roles.AddUserToRole(username,"USR");

数据正在aspnet_Users和aspnet_UsersInRoles中插入，但数据没有插入到aspnet_membership中，我需要这些数据，因为我正在使用asp登录控件。

有人可以帮助我吗？

试一试。我相信你没有传递所有参数。

string userName = txtUserId.Text;

//this value is either encrypted or hashed and is never displayed 
string password = txtPassword.Text; 

string email = txtEmail.Text;
string passwordQuestion = ddlPasswordQuestion.SelectedValue;

//this value is either encrypted or hashed and is never displayed 
string passwordAnswer = txtPasswordAnswer.Text;

MembershipCreateStatus result;
Membership.CreateUser(userName, password, email, passwordQuestion, passwordAnswer, true,out result);

lblResults.Visible = true;
switch (result) {
  case MembershipCreateStatus.Success:
    txtUserId.Text = null;
    txtPassword.Text = null;
    txtEmail.Text = null;
    ddlPasswordQuestion.SelectedIndex = -1;
    txtPasswordAnswer.Text = null;
    lblResults.Text = "User successfully created!";
    break;
  case MembershipCreateStatus.InvalidUserName:
    lblResults.Text = "The username format was invalid.  Please enter a different username.";
    break;
  case MembershipCreateStatus.InvalidPassword:
    lblResults.Text = "The password was invalid:  A password cannot be an empty string and must also meet the pasword strength requirements of the configured provider.  Please enter a new password.";
    break;
  case MembershipCreateStatus.InvalidEmail:
    lblResults.Text = "The email format was invalid.  Please enter a different username.";
    break;
  case MembershipCreateStatus.InvalidQuestion:
    lblResults.Text = "The password question format was invalid.  Please enter a different question.";
    break;
  case MembershipCreateStatus.InvalidAnswer:
    lblResults.Text = "The password answer format was invalid.  Please enter a different answer.";
    break;
  case MembershipCreateStatus.DuplicateUserName:
    lblResults.Text = "The username is already in use.  Please enter a new username.";
    break;
  case MembershipCreateStatus.DuplicateEmail:
    lblResults.Text = "The email address is already in use.  Please enter a different email address.";
    break;
  default:
    lblResults.Text = "An error occurred while creating the user.";
    break;
}

}

问题出在 if 语句中。它不起作用的原因是因为FindUsersByName方法返回MembershipUsers的集合。可能没有任何用户，但仍会返回一个集合。

请将声明更改为以下内容......

if (Membership.FindUsersByName(username).Count == 0)
{
    Membership.CreateUser(username, password, email);
}

应该这样做。
