检查foreach是否大于1
本文关键字:大于 是否 foreach 检查 | 更新日期: 2023-09-27 18:08:59
这是我的观点:
<form class="form-horizontal">
<div class="portlet-body form">
<div class="form-group">
@{
int i = 0;
}
@foreach (var group in ((List<DateTime>)ViewBag.MissingDays).GroupBy(x => x.Month))
{
i++;
var month = CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName(group.Key);
<div class="panel-group accordion" id="accordion1">
<div class="panel panel-default">
<div class="panel-heading">
<h4 class="panel-title">
<a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion1" href="#collapse_@i">
@month
</a>
</h4>
</div>
<div id="collapse_@i" class="panel-collapse collapse">
<div class="panel-body">
<div class="col-md-12">
@foreach (var date in group)
{
var isoDate = date.ToString("yyMMdd");
<label>
<input type="checkbox" id="isoDate" name="isoDate" value="@isoDate" />
@date.ToString("ddd").Substring(0, 2)
@isoDate
</label>
}
</div>
</div>
</div>
</div>
</div>
}
</div>
</div>
我在这里做的是将日期按月份分组,然后我有一个foreach来打印正确月份下的所有日期,所以所有属于may的日期都在may标签下,所有属于august的日期都在august标签下。
但是我想做的是,如果只有1个月,我不想打印出一个带有月份的标签,我只想打印出日期。
我想把它做成这样。如果一个组包含超过1个月的时间,那么就这样做。
在组中添加一个变量:
var groups = ((List<DateTime>)ViewBag.MissingDays).GroupBy(x => x.Month)
然后你可以检查它的计数:
<form class="form-horizontal">
<div class="portlet-body form">
<div class="form-group">
@{
int i = 0;
}
@foreach (var group in groups)
{
i++;
var month = CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName(group.Key);
<div class="panel-group accordion" id="accordion1">
<div class="panel panel-default">
@if(groups.Count() > 1)
{
<div class="panel-heading">
<h4 class="panel-title">
<a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion1" href="#collapse_@i">
@month
</a>
</h4>
</div>
}
<div id="collapse_@i" class="panel-collapse collapse">
<div class="panel-body">
<div class="col-md-12">
@foreach (var date in group)
{
var isoDate = date.ToString("yyMMdd");
<label>
<input type="checkbox" id="isoDate" name="isoDate" value="@isoDate" />
@date.ToString("ddd").Substring(0, 2)
@isoDate
</label>
}
</div>
</div>
</div>

</div>
}
</div>
