contains does not work

[young717]

In my case,
the api definite like this:
Task DeleteArticleById(params string[] articleId)
and the query expression like this :
predicate.And(s => articleIds.Contains(s.Id));
It does not work, it does not transform the contains function

Try Predicates.Field(f => f.NodeId, Operator.Eq, articleIds)
