Below is my existing code which using the LLBLGen version 1.x

bk.PredicateExpression.Add(PredicateFactory.CompareValue(UserFieldIndex.Login, ComparisonOperator.Equal, SearchCollection["UserId"]));

So according to the documentaion , we replaced the PredicateFactory with Ipredicate as

IPredicate predicate = UserFieldIndex.UserId.Equal(Convert.ToInt32(SearchCollection["UserId"]));

But we are not getting the exact result, getting error at UserFieldIndex.UserId saying that 'UserFieldIndex' doesn't contain a definition for Equal. Did I miss anything.? Could you please help on this

Use:

IPredicate predicate = UserFields.UserId.Equal(Convert.ToInt32(SearchCollection["UserId"]));

The index enum is for indexing inside a Fields object, you need to specify the field object itself. This wasn't present in v1, these field objects are generated and are introduced around v3.
