使用 Razor 显示列表<dynamic>

Display List<dynamic> with Razor

我在 Razor 视图中使用动态(匿名对象)列表并显示它。

控制器代码:

var res = (from c in _context.DM_Suivi_Us_Servis
                       group c by new { c.designation_magasin,c.designation_uf} into g
                       select new
                       {
                           g.Key.designation_magasin,
                           g.Key.designation_uf,
                           sum = g.Sum(c => c.nbr_us_servis),
                       }).ToList();

return View(res);

查看页面(Razor 视图):

@model IEnumerable<dynamic>
@foreach (var item in Model)
{
    <tr>
        <td>@item.ToString()</td>
    </tr>
}

显示此结果:

{ designation_magasin = CO3, designation_uf = NRG, sum = 65 }
{ designation_magasin = INC, designation_uf = NRG, sum = 0 } etc..

但是当我尝试显示每个项目属性时:

@foreach (var item in Model)
{
    <tr>
        <td>@item.sum</td>
        <td>@item.designation_uf</td>
        <td>@item.designation_magasin</td>
    </tr>
}

我收到以下错误

创建新视图模型:

public class YourName
{
    public string DesignationMagasin { get; set; }
    public string DesignationUf { get; set; }
    public int SumServis { get; set; }
}

并使用投影

var res = (from c in _context.DM_Suivi_Us_Servis
            group c by new { c.designation_magasin, c.designation_uf } into g
            select new YourName
            {
                DesignationMagasin= g.Key.designation_magasin,
                DesignationUf= g.Key.designation_uf,
                SumServis= g.Sum(c => c.nbr_us_servis),
            }).ToList();

在视图中添加 @model List<YourName>
