我有个视图，v_ep_alarm_log 有（BeginTime、EndTime、AreaId[区域]）等字段，我需要统计 最近7天各区域报警数量变化，请问下面的sql脚本如果转换成linq或Lamda？我转了几次运行都报错，提示无法翻译linq/lamda语句

SELECT CONVERT(VARCHAR(10), BeginTime, 120) AS DayDate ,
COUNT(CASE WHEN ( AreaID = 'FS' ) THEN 1
END) AS Fs4Count ,
COUNT(CASE WHEN ( AreaID = 'FSV' ) THEN 1
END) AS Fs5Count ,
COUNT(CASE WHEN ( AreaID = 'CA' ) THEN 1
END) AS CpCount ,
COUNT(CASE WHEN ( AreaID = 'Gygc' ) THEN 1
END) AS GCount
FROM dbo.v_ep_alarm_log
WHERE BeginTime >= '2021-07-01 00:00:00'
AND BeginTime < '2021-07-08 00:00'
GROUP BY CONVERT(VARCHAR(10), BeginTime, 120)
ORDER BY DayDate;
