包含 UTC 时区转换的 Linq 查询 where 子句

Question

I have a DB in Azure SQL Server where I have to compare the Date field against the current Eastern zone time, the SQL query where clause is like below

where CAST(getdate() AT TIME ZONE 'UTC' AT TIME ZONE 'Eastern Standard Time' as date) = mo.orderdate

Where current datetime in the Azure SQL DB is converted in to the EST time. I am not sure how I can convert above query to the linq query so I can use it in the C# like below

 where mo.orderdate ==  CAST(getdate() AT TIME ZONE 'UTC' AT TIME ZONE 'Eastern Standard Time' as date) 

but this doent work and errors

Answer 1

My bad as I was do the UTC conversion directly in the Query. I tried like below

        var timeUtc = DateTime.UtcNow;
        var easternZone = TimeZoneInfo.FindSystemTimeZoneById("Eastern Standard Time");
        var todayDt = TimeZoneInfo.ConvertTimeFromUtc(timeUtc, easternZone);

and used the todayDt in the where clause

where mo.OrderDate.Date == todayDt.Date
