Я пытаюсь добавить список ролей в основном веб-приложении asp.net на страницу Razor, но я не уверен, как это сделать.Я хочу, чтобы пользователь мог выбрать роль, которую должен зарегистрировать новый пользователь.
Сама модель ввода выглядит следующим образом:
public class InputModel
{
[Required]
[DataType(DataType.Text)]
[Display(Name = "Full name")]
public string Name { get; set; }
[Required]
[Display(Name = "Payroll")]
[DataType(DataType.Text)]
public string Payroll { get; set; }
[Required]
[EmailAddress]
[Display(Name = "Email")]
public string Email { get; set; }
[Required]
public List<String> Roles { get; set; }
[Required]
[StringLength(100, ErrorMessage = "The {0} must be at least {2} and at max {1} characters long.", MinimumLength = 6)]
[DataType(DataType.Password)]
[Display(Name = "Password")]
public string Password { get; set; }
[DataType(DataType.Password)]
[Display(Name = "Confirm password")]
[Compare("Password", ErrorMessage = "The password and confirmation password do not match.")]
public string ConfirmPassword { get; set; }
}
Как показано ниже, в настоящее время у меня жестко задан кодзначения на мой взгляд (выдержка):
<div class="form-group">
<label asp-for="Input.Roles"></label>
<select asp-for="Input.Roles" class="form-control">
<option value="Administrator">Administrator</option>
<option value="NormalUser" selected>NormalUser</option>
</select>
</div>
Это работает для того, что я хочу, но я хотел бы заменить это динамическим списком ролей из моего приложения.
У меня в методе OnGet () есть следующее
var roles = _roleManager.Roles.Select(x => x.Name).ToList();
InputModel vm = new InputModel();
vm.Roles = roles;
ReturnUrl = returnUrl;
Я спрашиваю, как привести список ролей в форму, которую я могу использовать на самой странице.
Спасибо.
