There are several ways in which you can achieve this:

+ Create your own bulk request class; You can use the attached file as an example:bulkdatarequestcs.txt . The initialisation routine will look like this:

     new BulkDataRequestSetup()

             .WithRics("LCOc1", ".SPX")

             .WithFields("CLOSE", "TIMESTAMP")

             .WithInterval(new Interval(IntervalType.Daily, 1))

             .WithNumberOfPoints(100)

             .OnDataReceived(DataReceivedCallback)

             .OnStatusUpdated(StatusUpdatedCallback)

             .CreateAndSend();

+ Reuse the same request object; after you received (chunk.isLast == true) in your DataReceivedCallback event, you can set up and send the next request, i.e. chain them.

I tried to access several Rics with your reference code, but I only get the first one "AUD=" rics' 24 ticks' data back, then the program stopped.

Would you please help to check why? the following is my code.

BulkDataRequestSettings RequestSettings = new BulkDataRequestSettings();
List<String> field_list = new List<string>();
List<String> rics_list = new List<string>();
RequestSettings.View = "BID";
rics_list.Add("AUD=");
rics_list.Add("AUDON =");
rics_list.Add("AUDSW =");
field_list.Add("CLOSE");
field_list.Add("TIMESTAMP");
RequestSettings.Rics = rics_list;
RequestSettings.Fields = field_list;
RequestSettings.From = new DateTime(2016, 9, 7, 15, 0, 0);
RequestSettings.To = new DateTime(2016, 9, 8, 15, 0, 0);
RequestSettings.Interval= CommonInterval.Intraday60Minutes;
RequestSettings.TimeZone = TimezoneType.GMT;
BulkDataRequest Request = new BulkDataRequest(RequestSettings);
Request.Send();

get rid of the space preceeding the equal sign, e.g., "AUDON=" not AUDON ="

What should I do if I want get multiple views at the same time, i.e. BID and ASK ?

Is it the same way as @Zhenya Kovalyov suggested?
