linq to sql select as command
From your previous question, I guess you have a query like, below. You can use select new to create an anonymous type object and then use OrderBy like:
var query = (from activeWO in context.ActiveWOs join activeWOUpdated in context.ActiveWOUpdatedTimes on activeWO.PW_ID equals activeWOUpdated.PW_ID into dj from activeWOUpdated in dj.DefaultIfEmpty() where activeWO.WODC.Contains("IDC") select new { TimeLeft = activeWO.StartTime * 60 * 60 * 24 - dj.ElapsedTime }).Orderby(r=> r.TimeLeft);
Use anonymous types:
var results = ... //your query .Select(a => new { TimeLeft = a.StartTime * 60 * 60 * 24 - a.ElapsedTime });
