尝试将模型添加到视图但不显示

Question

为什么我在图像上找不到模型：

ContactViewModel类是：

using System.ComponentModel.DataAnnotations;

namespace Moran.ViewModels
{
    public class ContactViewModel
    {
        [Required]
        [StringLength(255, MinimumLength = 5)]
        public string Name { get; set; }
        [Required]
        [EmailAddress]
        public string Email { get; set; }
        [Required]
        [StringLength(1024, MinimumLength = 5)]
        public string Message { get; set; }
    }
}

Contact.cshtml：

行：@model BazarMoran.ViewModels.ContactViewModel无法识别。

提前谢谢

Answer 1

您只是使用了错误的命名空间。

您的ViewModel被定义为Moran.ViewModels命名空间而不是BazarMoran.ViewModels。

然后你必须使用

@model Moran.ViewModels.ContactViewModel 

而不是

@model BazarMoran.ViewModels.ContactViewModel

或者只是将名称空间更改为ContactViewModel班级为BazarMoran.ViewModels。
