通过Linq（C#，Linq）过滤嵌套数据

Question

我有对象：

public class Cars
{
 public id CarId {get;set;}
 public ClientList[] AvaList {get;set;}
}

public class ClientList
{
 Client[] ClientData {get;set;}
}

public class Client
{
 int ClientId {get;set;}
}

在我获取汽车列表的方法中：

string cId = 10;
Cars cars = GetCars();
var carsForClientId = cars.AvaList.SelectMany(c => c.ClientData.Where(x => x.ClientId == cId));

但是

carsForClientId

是

IEnumerable<Client>

。我想得到

IEnumerable<Cars>

只包含

CliendId = 10

的数据；
