C# 使用SelectMany从列表中提取值并传递给组

我有下面的查询，我在列表中使用SelectMany，然后按列表的“Name”和“Count”分组，并将值存储在“Name”和“Count”中

var groups = originalList.SelectMany(fullList => fullList.ListOfItems, (fullList, details) => new { fullList.Name, fullList.ListOfItems })
                               .GroupBy(x => x.Name,
                                x => x.ListOfItems.Count())
                               .Select(g => new { Name = g.Key, Count = g.Count()});

//Do something with results        
foreach (var item in groups)
{
    var name = item.Name;
    var count = item.Count;
}

现在，我想将原始列表中的另一个参数传递给结果组，我们称之为fullList.SomeOtherValue

我如何修改上述内容，使其也能通过

我想以这个结尾：

foreach (var item in groups)
{
    var name = item.Name;
    var count = item.Count;
    var someother = item.SomeOtherValue;  <-- I want this as well
}

foreach（组中的变量项）
{
var name=item.name；
var count=项目计数；
var someother=item.SomeOtherValue；听起来像这样的东西应该可以工作：

originalList.SelectMany(fullList => fullList.ListOfItems)
                .GroupBy(x => new { x.Name, x.SomeOtherValue})
                .Select(g => new { g.Key.Name, g.Key.SomeOtherValue, Count = g.Count()});

听起来像这样的东西应该有用：

originalList.SelectMany(fullList => fullList.ListOfItems)
                .GroupBy(x => new { x.Name, x.SomeOtherValue})
                .Select(g => new { g.Key.Name, g.Key.SomeOtherValue, Count = g.Count()});
