Introduction 👀

Sequel Filter is a C# library that allows for filtering using a SQL-like syntax. The idea is to be able to provide end-users with completely customizable filtering without having to allow them to provide their own code or write your own filtering logic.

Installation 💾

Sequel Filter is available as a nuget package. You can also install the package using the .net CLI:

dotnet add package SequelFilter

• Simple injection-free filtering logic
• Support for matching single objects or filtering IEnumerables

Grammar Features ✍

• Combinational logic with AND / OR
• Support for IN, LIKE, BETWEEN and IS NULL SQL operators
• Support for searching child enumerables with HAS_NONE, HAS_ANY, HAS_SINGLE

Support 🤝

If you’d like to support the project but you don’t want to contribute code - a really good way to help is spread the word. There isn’t a donation or financial option because honestly I don’t need donations. I am, however, rubbish at ‘marketing’. So any help there would be greatly appreciated! Whether it’s a blog post or just telling some folks at the office - every little helps.
