ValueInjecter - Joins multiple result sets into 1 collection LINQ?

问题

How do I use ValueInjecter with a LINQ join that joins multiple result sets? For example, this code inject result values into CombinedResult object, but I also want some of errorsAndWarning values into CombinedResult. The properties have the same name:

var combined = from result in results.DeferredItems
               join errorsAndWarning in errorsAndWarnings.DeferredItems
                on result.MeetingID equals errorsAndWarning.MeetingID
               select new CombinedResult().InjectFrom(result) as CombinedResult;

Thanks.

Use this:

var combined = from result in results.DeferredItems
               join errorsAndWarning in errorsAndWarnings.DeferredItems
                on result.MeetingID equals errorsAndWarning.MeetingID
               select new CombinedResult().InjectFrom(result)
                                          .InjectFrom(errorsAndWarning)
                                          as CombinedResult;
