我正试图使用LINQ和C#从csv文件执行分组和计算行.
(样本csv)
T5,,929,,O,PPT-DAY,4,,,18.09,,ACXD:DSC,,,,,,,,,,,
T5,,929,,O,PPT-DAY,4,,,18.09,,ACXD:DSC,,,,,,,,,,,
T5,,644,,O,PPT-ANNUAL LEAVE,1,,,850.23,,INTERNAL,,,,,,,,,,,
T5,,900,,O,PPT-ANNUAL LEAVE,1,,,42.51,,INTERNAL,,,,,,,,,,,
T5,DEFAULT,674,,O,PPT-DAY,2,,,18.09,,ACXD:DSC,,,,,,,,,,,
T5,,674,,O,PPT-PERSONAL LEAVE-ON,8,,,19.9,,INTERNAL,,,,,,,,,,,
SQL等价
SELECT Col3
,Col5
,Col6
,SUM(Col7) as [hours]
,AVG(Col10) as [pay]
,Col12
FROM mytable
GROUP BY Col3, Col5, Col6, Col12
ORDER BY Col3, Col5, Col6, Col12
我使用其他线程进行了一些尝试,但我正在努力进行多列分组和计算.任何建议将不胜感激.
