list of XmlaMessage.Description values

XmlaResultCollection oResults = svr.ExecuteCaptureLog(false,false);

foreach (XmlaResult oResult in oResults)
          foreach (XmlaMessage oMessage in oResult.Messages)
              if (oMessage.Description == Value1 OR oMessage.Description == Value2...)
                   return;

I want to stop the execution if there was an error.

What I am looking for, is the list of possible Descriptions resulting from the process in order to stop if failed.
