我必须这样列出：
@foreach($user->contact as $contact)

<i style="font-size: 13px;" class="icon-user"></i>
@elseif($contact->role[0]->slug =='organizations')
<i style="font-size: 13px;" class="icon-hotel-restaurant-172 u-line-icon-pro fa- fa-lg"></i>
@endif

@break;
@endforeach

我想将列表合并为一个。将文章与所有度量单位组合在一个交流列表中，仅使用名称文章，ID度量单位，Name度量单位。
您可以为列表中的每个项目执行两个循环，但是我想知道是否有一种方法可以使linq变得更简单。
Foreach示例：
IEnumerable<Entities.Article> articlelist;
IEnumerable<Entities.MeasureUnit> measureList
答案 0 :(得分：0)
您可以使用SelectMany来构建此笛卡尔积：
IEnumeable<Models.SearchItem> searchItems = articlelist
.SelectMany(article => measureList, (a, m)
=> new Models.SearchItem() { IDItem = m.IDMeasureUnit, PrincipalProperty = a.Description, SecondaryProperty = m.Description });
