我在LINQ联接中有一个非常奇怪的行为
我正在加入一个IEnumerable集合和一个我通过Entity Framework访问的视图。
例如（数字是列值）：
集合
1 1
1 2
查看
1 3
1 4
联接的结果应该是
1 1 1 3
1 1 1 4
1 2 1 3
1 2 1 4
我在管理工作室得到了T-SQL的结果，甚至在LinqPad中使用了相同的代码， 但是在VS中我得到了
1 1 1 3
1 1 1 3
1 2 1 3
1 2 1 3
或
1 1 1 4
1 1 1 4
1 2 1 4
1 2 1 4
但从未正确加入。我通过SQL Server Profiler检查Linq生成的查询并在Managment Stuiod中启动它，并得到了正确的答案。请帮助我理解这种非常奇怪的行为
var allocations = InvoicingContext.vAllocations.Where(x => auditIds.Contains(x.AuditGroupId.Value)).AsEnumerable();
var q = from a in allocations
join c in CommonCodesContext.vContainerEntity on a.ContainerId equals c.ContainerId
select new ContainerServiceModel
{
ContainerNo = a.ContainerNo,
PortATD = c.ATD,
ATA_KL = a.ServiceDate,
RateWithoutVat = a.RateWithoutVat,
DestinationCityId = c.DestinationCityId,
Quantity = 1
};
var containerServiceModels = q.ToList();
int destinationCount = containerServiceModels.Where(x => x.DestinationCityId == 14).Count();

我试图循环并根据谓词来计算结果集合
Invoicing_SPBEntities invContext = new Invoicing_SPBEntities();
CommonCodesEntities ccContext = new CommonCodesEntities();
for (int i = 0; i <= 20; i++)
{
var allocations = (from a in invContext.vAllocations
where a.AuditGroupId == 9107
select a).AsEnumerable();
var q = from a in allocations
join c in ccContext.vContainerEntity on a.ContainerId equals c.ContainerId
select new
{
ContainerNo = a.ContainerNo,
PortATD = c.ATD,
ATA_KL = a.ServiceDate,
RateWithoutVat = a.RateWithoutVat,
OrderTypeId = c.OrderTypeId,
DestinationCityId = c.DestinationCityId,
Quantity = 1
};
var result = q.ToList();
Console.WriteLine(result.Where(x=>x.DestinationCityId == 14).ToList().Count);
}
产生的控制台输出
64 62 58 58 64 62 60 60 56 60 62 60 58 54 56 64 58
非常奇怪：D
