LINQ-通过配对对象的键对，然后将组合对象分成2个对象的列表？

IsApproved

IsApproved

public class Object
{
    public int Id { get; set; }
    public int MatchId { get; set; }
    public string Name { get; set; }
    public bool IsApproved { get; set; }
}

1 123ABC SomeName True

2 123ABC SomeElse False

3 321CBA Name2 True

4 321CBA Name3 False

5 987ASD NameName True

6 987ASD TestTest False

public class Program
{
    public List<PairedObject> PairedObjects { get; set; }
}

public class PairedObject
{
    public Object IsApproved { get; set; }
    public Object NotApproved { get; set; }
}

list.GroupBy(o => o.MatchId)
    .Select(g => new PairedObject
                     {
                         IsApproved = g.First(o => o.IsApproved),
                         NotApproved = g.First(o => !o.IsApproved)
                     });
