Question

我仍然使用asp.net MVC找到了我的脚。

我想从viewModel生成一个详细信息视图，但我没有让控制器正确，所以它说我将错误类型的模型传递给视图。

控制器目前是：

    public ActionResult ClubDetails(int clubId)
    {
        //Populate the view
        var clubs = from s in db.Clubs
                    orderby s.Name
                    select s;
        var viewModel = clubs.Select(t => new ClubDetailsViewModel
        {
            Name = t.Name,
            ShortName = t.ShortName,
            Founded = t.Founded,
            ContactName = t.FirstName + " " + t.LastName,
            Address1 = t.Address1,
            Address2 = t.Address2,
            City = t.City,
            County = t.County,
            Postcode = t.Postcode,
            Telephone = t.Telephone,
            Email = t.Email,
            Bio = t.Bio,
            Website = t.Website,
        });
        return View(viewModel);
    }

viewModel是：

    public class ClubDetailsViewModel
{
    [Display(Name = "Club Name")]
    public string Name { get; set; }

    [Display(Name = "Abbreviation")]
    public string ShortName { get; set; }

    [Display(Name = "Founded")]
    [DataType(DataType.Date)]
    [DisplayFormat(DataFormatString = "{0:dd/MM/yyyy}", ApplyFormatInEditMode = true)]
    public DateTime? Founded { get; set; }

    [Display(Name = "Contact Name")]
    public string ContactName { get; set; }

    [Display(Name = "Address 1")]
    public string Address1 { get; set; }

    [Display(Name = "Address 2")]
    public string Address2 { get; set; }

    [Display(Name = "City")]
    public string City { get; set; }

    [Display(Name = "County")]
    public string County { get; set; }

    [Display(Name = "PostCode")]
    public string Postcode { get; set; }

    [Display(Name = "Telephone")]
    public string Telephone { get; set; }

    [EmailAddress]
    [Display(Name = "Email")]
    public string Email { get; set; }

    [Display(Name = "Website")]
    [Url]
    public string Website { get; set; }

    [Display(Name = "Bio")]
    public String Bio { get; set; }
}

观点是：

@model GRCWebApp.ViewModels.ClubDetailsViewModel

@{
ViewBag.Title = "ClubDetails";
}

<h2>ClubDetails</h2>

<div>
<h4>ClubDetailsViewModel</h4>
<hr />
<dl class="dl-horizontal">

Answer 1

您传递的是IEnumerable<ClubDetailsViewModel>，而不是ClubDetailsViewModel。你可能想要过滤你的球杆并选择一个，而不是对所有球杆进行这样做。像这样：

var viewModel = db.Clubs
    .Where(t => t.ClubID == clubID)
    .Select(t => new ClubDetailsViewModel
    { .. })
    .FirstOrDefault();
return View(viewModel);

Answer 2

或添加

 @Model List<ClubDetailsViewModel>

到你的观点并循环俱乐部

详细信息使用viewModel查看Controller方法
