我正在尝试遵循以下帖子中介绍的模式：
我遇到了一个问题。我已将代码完全按照显示的方式复制到我自己的应用程序中，但是当表单回发时，模型的角色集合的 RoleName 属性为 null。从复选框发布的值是正确的，但 RoleName 不具有约束力。
下面是我正在使用的代码：
注册.cshtml
@model SimpleMembershipTest.Models.RegisterViewModel
@{
ViewBag.Title = "Register";
}
<hgroup class="title">
<h1>@ViewBag.Title.</h1>
<h2>Create a new account.</h2>
</hgroup>
@using (Html.BeginForm()) {
@Html.AntiForgeryToken()
@Html.ValidationSummary()
<fieldset>
<legend>Registration Form</legend>
<ol>
<li>
@Html.LabelFor(m => m.UserName)
@Html.TextBoxFor(m => m.UserName)
</li>
<li>
@Html.LabelFor(m => m.FirstName)
@Html.TextBoxFor(m => m.FirstName)
</li>
<li>
@Html.LabelFor(m => m.LastName)
@Html.TextBoxFor(m => m.LastName)
</li>
<li>
@Html.LabelFor(m => m.Password)
@Html.PasswordFor(m => m.Password)
</li>
<li>
@Html.LabelFor(m => m.ConfirmPassword)
@Html.PasswordFor(m => m.ConfirmPassword)
</li>
<li>
@Html.LabelFor(m => m.Email)
@Html.TextBoxFor(m => m.Email)
</li>
</ol>
<div class="roleCheckBoxes">
@Html.EditorFor(m => m.Roles)
</div>
<input type="submit" value="Register" />
</fieldset>
}
@section Scripts {
@Scripts.Render("~/bundles/jqueryval")
}
RegisterViewModel.cs
namespace SimpleMembershipTest.Models
{
public class RegisterViewModel
{
[Required]
[Display(Name = "User name")]
public string UserName { get; set; }
[Required]
[Display(Name = "First name")]
public string FirstName { get; set; }
[Required]
[Display(Name = "Last name")]
public string LastName { get; set; }
[Required]
[StringLength(100, ErrorMessage = "The {0} must be at least {2} 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; }
[Required]
[EmailAddress]
[Display(Name = "Email")]
public string Email { get; set; }
public IEnumerable<RoleViewModel> Roles { get; set; }
}
}
角色视图模型.cs
@model SimpleMembershipTest.Models.RoleViewModel
@Html.CheckBoxFor(m => m.Selected)
@Html.LabelFor(m => m.Selected, Model.RoleName)
AccountController.cs
[AllowAnonymous]
public ActionResult Register()
{
var roles = Roles.GetAllRoles();
var model = new RegisterViewModel
{
Roles = roles.Select(role => new RoleViewModel
{
RoleName = role,
Selected = false
})
};
return View(model);
}
我可能遗漏了一些明显的东西，但我似乎看不到它。任何帮助将不胜感激。
