Linq order by aggregate in the select { }

Question

Here is one I am working on:

var fStep =
            from insp in sq.Inspections
            where insp.TestTimeStamp > dStartTime && insp.TestTim         


        

Answer 1

You can move the select value to a let assignment and then build an order by after that.

var fStep =
    from insp in sq.Inspections
    where insp.TestTimeStamp > dStartTime && insp.TestTimeStamp < dEndTime
       && insp.Model == "EP" && insp.TestResults != "P"
    group insp by new { insp.TestResults, insp.FailStep } into grp
    let newInsp = new
    {
        FailedCount = (grp.Key.TestResults == "F" ? grp.Count() : 0),
        CancelCount = (grp.Key.TestResults == "C" ? grp.Count() : 0),
        grp.Key.TestResults,
        grp.Key.FailStep,
        PercentFailed = Convert.ToDecimal(1.0 * grp.Count() / tcount * 100)

    }
    orderby newInsp.FailedCount, newInsp.CancelCount
    // or this ...
    //orderby newInsp.FailedCount
    //orderby newInsp.CancelCount
    select newInsp;
;
