由属性值组合对象 [英] Grouping objects by property value

问题描述

我有一点麻烦搞清楚了这一点。我有一个对象具有两个属性的列表：别名和值

I'm having a bit of trouble figuring this out. I have a list of objects with two properties: Alias and Value

我需要证明这些对象所在的别名属性由值字符串值分组列表。像这样的：

I need to show a list of these objects where the Alias property is grouped by the Value string value. Like this:

MyAlias1, MyAlias2, MyAlias3
     - Value string which is the same for above three aliases

MyAlias4, MyAlias5
     - Value string which is the same for above three aliases

我至今是：

var groups = lst.GroupBy(x => new { x.Alias, x.Value });
foreach(var group in groups)
{
    @group.Value
}

但我不知道该怎么从那里做，实际显示他们作为分组的项目。

But I'm not sure what to do from there, to actually show them as grouped items.

任何帮助是极大AP preciated！

Any help is greatly appreciated!

推荐答案

我觉得你的价值需要组，然后每个组可以打印出你所需要的：

I think you need to group by the value, then for each group you can print out what you need:

@{ var groups = lst.GroupBy(x => x.Value); }

@foreach (var group in groups)
{
    var aliasString = String.Join(",", group.Select(x => x.Alias));
    <p>@aliasString</p>
    <p>- @group.Key</p>
}
