c# - MVC动态模型查看

Question

the model item passed into the dictionary is of type 'System.Collections.Generic.Dictionary2[CapacityPlanner2.Models.Segment, CapacityPlanner2.Models.Product]', but this dictionary requires a model item of type 'System.Collections.Generic.Dictionary2[System.Object,System.Object]

我的 View 有@model Dictionary<dynamic, dynamic>

我正在传递以下 Dictionary<Project, Segment>

这不可行吗？

我的局部 View :

@model Dictionary<dynamic, Dictionary<dynamic, List<dynamic>>>

我的主视图

@model  Dictionary<dynamic, Dictionary<dynamic, Dictionary<dynamic, List<dynamic>>>>


@foreach (var kvp in Model) 
{   
    @Html.Partial("_part", kvp.Value)
}

我想添加部分 View ，因为我想重用它。但在此之前一切正常。

如评论中所述，您必须在创建模型时传递 dynamic 类型。这是一个工作示例。但正如评论中提到的，请检查您是否真的需要dynamic，可能interfaced model 就足够了。

    public ActionResult Testing()
    {
        var data = new Dictionary<dynamic, Tuple<dynamic, dynamic>>
        {
            {1, new Tuple<dynamic, dynamic>(new Project{Name = "P1"}, new Segment{Id = "S1"})},
        };

        return View(data);
    }

    @foreach (var d in @Model)
          {
                  var item1 = @d.Value.Item1 as Project;
                  var item2 = @d.Value.Item2 as Segment;
                  <p> @d.Key + ": "  + @item1.Name + " - " + @item2.Id</p>
          }
