c# - 找不到模型

Question

我已经包含了一个模型并创建了一个 View 文件以及一个 Controller 来控制所有这些

public class CreateNewUserModel
{
    [Required]
    [Display(Name = "User name")]
    public string UserName { get; set; }

    [Required(ErrorMessage = "Email required")]
    [EmailAddress(ErrorMessage = "Not a valid email")]
    public string UserEmail { 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]
    [Display(Name = "Role")]
    public string UserRole { get; set; }
    public IEnumerable<System.Web.Mvc.SelectListItem> UserRoles { get; set; }
}

在 View 文件之上

我还有@model CreateNewUserModel

这是我得到的编译错误

Answer 1

您只需完全指定模型类型的名称或导入模型的命名空间。

例如

@model MyNamespace.CreateNewUserModel

或

@using MyNamespace
@model CreateNewUserModel

显然，将上面示例中的“MyNamespace”替换为您在其中定义模型类的命名空间。
