Question

我想按“TimeName”字段对返回的项目进行分组，所以我不想在每一行重复字段TimeName，代码如下：

@foreach (var item in Model) {


      tim = item.MealTime;


 @Html.DisplayFor(modelItem => item.TimeName)
<text> , </text>        
   @Html.DisplayFor(modelItem => item.MealTime)

        <br />      
            @Html.DisplayFor(modelItem => item.FoodName)
            @Html.DisplayFor(modelItem => item.Quantity)
            @Html.DisplayFor(modelItem => item.FoodUnit)

            @Html.DisplayFor(modelItem => item.MealDate)
            @Html.DisplayFor(modelItem => item.MealTimeSpecific)
            @Html.DisplayFor(modelItem => item.IsActive)
            @Html.DisplayFor(modelItem => item.InsertDate)
            @Html.DisplayFor(modelItem => item.InsertUser)

    <br />
 }

我试图制作嵌套for循环，但它不起作用，有没有办法解决这个问题？

我找到了一个解决方案，但我希望能有更好的解决方案，

 @{
      tim = Model.FirstOrDefault().MealTime;
  }

     @Model.FirstOrDefault().TimeName
    <br />

@foreach (var item in Model) {
    if (tim != item.MealTime)
    {
 @Html.DisplayFor(modelItem => item.TimeName)
        <br />
}

    tim = item.MealTime;


          @Html.DisplayFor(modelItem => item.MealTime)
            @Html.DisplayFor(modelItem => item.FoodName)
            @Html.DisplayFor(modelItem => item.Quantity)
            @Html.DisplayFor(modelItem => item.FoodUnit)

            @Html.DisplayFor(modelItem => item.MealDate)
            @Html.DisplayFor(modelItem => item.MealTimeSpecific)
            @Html.DisplayFor(modelItem => item.IsActive)
            @Html.DisplayFor(modelItem => item.InsertDate)
            @Html.DisplayFor(modelItem => item.InsertUser)

    <br />

}

for循环中每个特定字段的组项（无sql）
