asp.net设置html控件的display属性,ASP.NET - HTML.Display不显示值

@model IEnumerable

@foreach (var item in Model.GroupBy(m => m.DayName).Distinct())

{

@Html.Display(item.Select(x => x.DayName).ToString())

ExerciseName

ExerciseTime

ExerciseRepetition

MomentOfTheDay

Routine

Week

@foreach (var test2 in item)

{

@Html.DisplayFor(modelItem => test2.ExerciseName)

@Html.DisplayFor(modelItem => test2.ExerciseTime)

@Html.DisplayFor(modelItem => test2.ExerciseRepetition)

@Html.DisplayFor(modelItem => test2.MomentOfTheDay)

@Html.DisplayFor(modelItem => test2.Routine.RoutineID)

@Html.DisplayFor(modelItem => test2.ExerciseWeek)

}

}

一切工作正常，但

@Html.Display(item.Select(x => x.DayName).ToString())

我只是想展现天名称上表因为它按天分组，但显示代码不会显示任何内容。我试过使用DisplayFor，但显然它不接受表达式。或者，也许我做错了。
