Subquery filtering through extension-method

Asked 2021-Nov-22 at 12:39

Background

I'm trying to clean up my code by extracting some code into some extension methods, as shown below. I stumbled upon LINQKit, which has the Expandable functionality. I created a simple extension method AtPointInTime, which takes a DateTimeOffset as input (See code below), but I keep getting an error. What am I doing wrong (Can't find a solution in the documentation)?

As mentioned in the comments, you just need to use the AsQueryable method on the collection to pass in the Expression> as the filter.

You are on the right track with Or predicate, but instead of multiple Or predicates on user.UserDepatments.Any(single_match) you should create single Or based predicate to be used inside the single user.UserDepatments.Any(multi_or_match).

Something like this:

It seems that EF-core 5 doesn't play nice with AsExpandable. Or rather the other way around. It worked with EF3, but apparently Linqkit isn't resilient to library-specific idiosyncrasies of expression trees.

There is a work-around for this case. As expained here, predicate is not an Expression, but an ExpressionStarter, which implicitly converts to Expression> and Func. Therefore, queries with predicates on top-level entities (say: EF's IQueryables) work without AsExpandable:

Answered 2020-Jun-19 at 17:13

You have to expressly tell linq that you are expanding the sub expressions - just like when you utilize .AsExpandable() on the table - when invoking in a sub set you must expand the parent to traverse the tree and expand the sub expressions.

So.... all you need is to add an Expand to the parent expression, in this case

QUESTION

How can I Refactor This To Pass in the "Property to Use" in this Lambda to Make This Method Reusable?

Asked 2020-Feb-07 at 21:34

In my web page, there are multiple textboxes where users can enter complex queries. A complex query can contain any of the following Parameters:

XX* that matches everything starting with XX
*XX for everything ending in XX
*XX* for everything containing XX
XX123-XX129 for everthing matching the inclusive range from XX123 to XX129
XX444 for an exact individual value
... any comma separated combination of any/all of the above

Implementing that is not my problem; my problem is implementing it for multiple values in a reuseable manner.

The sample below filters Items on the Item.Value property.

The issue is probably caused by an obsolete version of NuGet agent. You can try using NuGet Install Tool task and setup the agent to the v5.x, before using NuGetCommand restore task.
