Pass expression to filter.By method #33

Closed MaklaCof closed 5 years ago

Hi! Is it possible to use expression for filtering.

Something like that:

var filter = new Filter<DbMyEntity>();
filter.By("Field3", Operation.IsNotNull);
filter.By(t => !t.Field1.HasValue || t.Field1.HasValue && array.Contains(t.Field1.Value), Connector.Or);
filter.By("Field2", Operation.IsEmpty);

That would be super awesome.

Hi @MaklaCof, Sorry for the late reply. That's currently not supported. So, what would exactly be the use for this? Why do you need to use the filter in those two different ways? Cheers.

I can't remember. Sorry. I moved on with LINQ Dynamic.
