但是linq无法达到预期的结果，可以循环实现结果而不是linq吗？ （对不起，我是C＃的初学者）
来源1＆amp;中的项目2完全相同
Source1：分组表
ItemCode|TotalQty|Shipment|Remarks|Line
=========================================
ITEM01 | 1000 | S001 | R001 | 1 <==10 items here
ITEM01 | 400 | S002 | R002 | 2 <==4 items here
ITEM02 | 2000 | S003 | R003 | 3 <==2 items here
Source2：详情表（14项＆amp;行）
RefNo|ItemCode|Quantity|Weight|From
=======================================
R001 | ITEM01 | 100 | 50 | US
R002 | ITEM01 | 100 | 50 | US
R003 | ITEM01 | 100 | 50 | US
. | . | . | . | .
. | . | . | . | .
R013 | ITEM01 | 100 | 50 | US
R014 | ITEM01 | 100 | 50 | US
R015 | ITEM02 | 1000 | 100 | US
R015 | ITEM02 | 1000 | 100 | US
我想将source1和source2结合起来，得到如下结果
Shipment|Line|Remarks|ItemCode|TotalQty|RefNo|Quantity|Weight|From

对此有何想法？谢谢你的帮助。
