必需属性在 ASP.NET 中不起作用

Question

我创建了这个 C# 文件以在 ASP.NET 5.0 中搭建脚手架。问题是我不希望需要家庭号码，但生成的页面（带有 Entity Framework 的控制器）Create 仍然将其计算在内。知道为什么会发生这种情况吗？

public class Patient
    {
        [Key]
        public string MRN { get; set; }
        [Required]
        public string FirstName { get; set; }
        [Required]
        public string MiddleName { get; set; }
        [Required]
        public string LastName { get; set; }
        [Required]
        public string Address { get; set; }
        [Required]
        public string Gender { get; set; }
        [Required]
        [Display(Name = "Mobile Number")]
        public int MobNumber { get; set; }       
        [Display(Name = "Home Number")]
        public int HomeNumber { get; set; }      
        [Required]
        public string Nationality { get; set; }
            

    }

这里是 Create.cshtml 的代码，以前它运行起来很奇怪，现在每次我尝试生成控制器和视图时，都需要家庭号码。

@{
    ViewData["Title"] = "Create";
}

<h1>Create</h1>

<h4>Patient</h4>
<hr />
<div class="row">
    <div class="col-md-4">
        <form asp-action="Create">
            <div asp-validation-summary="ModelOnly" class="text-danger"></div>
            <div class="form-group">

                <input asp-for="MRN" class="form-control" />

<div>
    <a asp-action="Index">Back to List</a>
</div>

@section Scripts {
    @{await Html.RenderPartialAsync("_ValidationScriptsPartial");}
}

如果您不希望值是必需的，您应该使它们可以为空：

[Display(Name = "Home Number")]
public int? HomeNumber { get; set; }
