DatePart中的SQL到LINQ转换错误

Question

请帮我将以下SQL转换为LINQ：

SELECT Row_Number() OVER (ORDER BY NewHireID) AS RowNo,
       NewHireID, 
       SUM(HoursWorked) WeeklyWorkedHours, 
       CONVERT(varchar, DATEPART(WK, (WORKDATE))) WeekNo
FROM dbo.TBLTIMESHEET
GROUP BY NewHireID, DATEPART(WK, (WORKDATE))

使用LINQPAD但是出现以下错误 SQL语法错误：函数DATEPART的参数WK无效。

提前致谢。
