C# 如何从模型中访问第二个iCollection并迭代该集合以获取其数据类型？

在我看来，有没有一种方法作为它的模型Exer_锻炼，来访问：Exer_Set_Pivot的深嵌套ICollection，并在foreach循环中获取其成员的数据类型？ 头等舱：

public partial class Exer_Workout
{
    public Exer_Workout()
    {
        this.Exer_Routine = new HashSet<Exer_Routine>();
    }

    public int ObjID { get; set; }
    public string Name { get; set; }
    public string Description { get; set; }
    public string Notes { get; set; }
    public System.DateTime StartTime { get; set; }
    public Nullable<System.DateTime> EndTime { get; set; }

    public virtual ICollection<Exer_Routine> Exer_Routine { get; set; }
}

第二款车型第一款车型的一对多：

public partial class Exer_Routine
{
    public Exer_Routine()
    {
        this.Exer_Set_Pivot = new HashSet<Exer_Set_Pivot>();
    }

    public int ObjID { get; set; }
    public int WorkoutID { get; set; }
    public string Name { get; set; }
    public string Description { get; set; }
    public string Notes { get; set; }
    public Nullable<System.DateTime> StartTime { get; set; }
    public Nullable<System.DateTime> EndTime { get; set; }

    public virtual Exer_Workout Exer_Workout { get; set; }
    public virtual ICollection<Exer_Set_Pivot> Exer_Set_Pivot { get; set; }
}

我的第三个模型类与我的第二个模型类有一对多：

public Exer_Set_Pivot()
    {
        this.Exer_Set = new HashSet<Exer_Set>();
    }

    public int ObjID { get; set; }
    public int RoutineID { get; set; }
    public string Name { get; set; }
    public string Description { get; set; }
    public bool Weight { get; set; }
    public bool WeightUnit { get; set; }
    public bool Reps { get; set; }
    public bool Challenge { get; set; }
    public bool ElapsedTime { get; set; }
    public bool Distance { get; set; }
    public bool DistanceUnit { get; set; }
    public bool Speed { get; set; }
    public bool SpeedUnit { get; set; }

    public virtual Exer_Routine Exer_Routine { get; set; }
    public virtual ICollection<Exer_Set> Exer_Set { get; set; }
}

我的局部视图，需要访问Exer_Set_Pivot成员并确定其日期类型，如果是类型BOOL，则将其设置为复选框：

@model Diabuddies.Models.Exer_Workout


<fieldset>
<legend>Set @ViewBag.SC   </legend>
<table>
    <tr>
        <td>
            Name:
        </td>
        <td>
            @Html.TextBoxFor(x => x.Exer_RoutineList[Model.RoutineCount].Exer_SetPivotList[Model.SetCount].Name)
            @* <input type="text" name="Workout.Exer_Routine[@ViewBag.RC].Exer_Set_Pivot[@ViewBag.SC].Name"> *@ 
        </td>
    </tr>
    <tr>
        <td>
            Description:
        </td>
        <td>
            @Html.TextBoxFor(x => x.Exer_RoutineList[Model.RoutineCount].Exer_SetPivotList[Model.SetCount].Description)
        </td>
    </tr>
    <tr>
        <td>Repeat Set:</td>
        <td>
           @Html.TextBoxFor(x => x.Exer_RoutineList[Model.RoutineCount].Exer_SetPivotList[Model.SetCount].RepeatSet, new { maxlength=3 }) 
        </td>
    </tr>
    >>>>>HERE<<<<< DSFSADLFSDLFK DSL FKDSLFKLDSKF
    @foreach (dfgdfgdfg)
    {

        @*This is where I am stuck.  Need to get Exer_Set_Pivot's members and determine their type *@

           <tr>
           <td>
               System.Collections.Generic.List
           </td>
           <td>
               @(listitem.GetType()) and put it into checkbox, just need to get here.
           </td> 
           </tr> 

    }   
   </table>

您可以通过反射实现所有这些，但这将导致一个非常可怕的代码。您最好访问视图模型的各个成员：

@foreach (Exer_Routine routine in Model.Exer_Routine)
{
    <tr>
    @foreach (Exer_Set_Pivot pivot in routine.Exer_Set_Pivot)
    {
        <td>
            @Html.TextBoxFor(x => x.Name)
        </td>
        <td>
            @Html.TextBoxFor(x => x.Description)
        </td>
        <td>
            @Html.CheckBoxFor(x => x.Weight)
        </td>
        <td>
            @Html.CheckBoxFor(x => x.WeightUnit)
        </td>
        ...
    }
    </tr>
}

Exer_例程无法像这样访问。而且我只在类型为bool时创建复选框。你说它不可访问是什么意思？您的视图模型是Exer_锻炼，它有一个名为Exer_例程的属性，因此正是通过model.Exer_例程，您可以访问Exer_例程中的这个集合属性。var例程有效-我的错，谢谢。但是现在我可以深入到Exer\u Set\u Pivot，如何迭代该模型，以及如果system.type==bool，如何捕获？
