再向默认index.cshtml razorpages asp.net core 2.1.0添加一个属性

我正在使用 Asp.Net Core 2.1.0 在一个项目中,我想额外添加一个 property 默认脚手架 Index.cshtml 页。

这是我的实体,请建议。

public class Role
{
    public int RoleId { get; set; }
    public string RoleName { get; set; }

    public ICollection<UserRole> UserRole { get; set; }
}
public class User
{
    [DatabaseGenerated(DatabaseGeneratedOption.None)]
    public string UserName { get; set; }
    public string Password { get; set; }
    public string MobileNumber { get; set; }
    public string Email { get; set; }

    public ICollection<UserRole> UserRole { get; set; }
}
public class UserRole
{    
    public int Id { get; set; }
    public string UserName { get; set; }
    public int RoleId { get; set; }

    [ForeignKey("RoleId")]
    public Role Role { get; set; }
    [ForeignKey("UserName")]
    public User User { get; set; }
}

现在,默认的脚手架 索引文件 显示器 RoleID 和 UserName 我想在哪里再加一个冒号,即 RoleName 哪一个在 Role entity .

清单应该是 RoleID, RoleName, UserName

这是我的脚手架页面模型。

public class IndexModel : PageModel
{
    private readonly Test.Models.TestContext _context;

    public IndexModel(Test.Models.TestContext context)
    {
        _context = context;
    }

    public IList<UserRole> UserRole { get;set; }

    public async Task OnGetAsync()
    {
        UserRole = await _context.UserRole
            .Include(u => u.Role)
            .Include(u => u.User).ToListAsync();
    }
}

请在不干扰其他页面的情况下帮助我,如 Edit, Detail, Delete.

更新:index.cshtml中的代码

    @page
@model Test.Pages.UserRoles.IndexModel

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

<h2>Index</h2>

<p>
    <a asp-page="Create">Create New</a>
</p>
<table class="table">
    <thead>
        <tr>
            <th>
                @Html.DisplayNameFor(model => model.UserRole[0].Role)
            </th>
            <th>
                @Html.DisplayNameFor(model => model.UserRole[0].User)
            </th>
            <th></th>
        </tr>
    </thead>
    <tbody>
        @foreach (var item in Model.UserRole)
        {
            <tr>
                <td>
                    @Html.DisplayFor(modelItem => item.Role.RoleId)
                </td>
                <td>
                    @Html.DisplayFor(modelItem => item.User.UserName)
                </td>
                <td>
                    <a asp-page="./Edit" asp-route-id="@item.Id">Edit</a> |
                    <a asp-page="./Details" asp-route-id="@item.Id">Details</a> |
                    <a asp-page="./Delete" asp-route-id="@item.Id">Delete</a>
                </td>
            </tr>
        }
    </tbody>
