join 2 query results orderby two different values

Assuming this object:

DXMessage
{
    public byte[] msg;
    public int time;
    public int millisecond;
}

and assuming that I have 2 sorted lists:

public static SortedList<long, DXMessage> brimstoneMessages = 
            new SortedList<long, DXMessage>();

publi开发者_如何学Goc static SortedList<long, DXMessage> gpsMessages =
            new SortedList<long, DXMessage>();

I have executed 2 queries on 2 different lists of messages:

var bsQuery = GlobalObjects.bsMessages.Where(t =>
            ((t.Value.Time >= eventStart))).ToList();

var gpsQuery = GlobalObjects.gpsMessages.Where(t =>
            ((t.Value.Time >= eventStart))).ToList();

I would like to take the results of these 2 queries, and join them in ascending order by Time and millisecond.

By "join" do you mean "concatenate" rather than a sort of SQL join? I suspect you just want:

var combined = bsQuery.Concat(gpsQuery)
                      .OrderBy(x => x.Value.time)
                      .ThenBy(x => x.Value.millisecond);

It's not clear why you've got so many brackets in your queries by the way - and in this case it looks like you could actually perform the combination earlier:

var combined = GlobalObjects.bsMessages
                            .Concat(GlobalObjects.gpsMessages)
                            .Where(t => t.Value.Time >= eventStart)
                            .OrderBy(t => t.Value.Time)
                            .ThenBy(t => t.Value.Millisecond);
