Lambda Expression Builder

This is not a replacement of LambdaExpressionBuilder. I've just built on top of it; made changes and improvements (in my opinion)

Are you looking for a library that can build lambda expressions easily? Use the Lambda Expression Builder to easily build a filter that you can apply to lists and database queries. You can even use this as a base to allow you to build filters dynamically.

Packed with features; you can save and re-run filters, not have to worry about NULL checks (it's automatic), build complex queries with groups and more!


  • Ability to reference properties by their names
  • Ability to reference properties from a property
  • Ability to reference properties from list items
  • Built-in null-checks
  • Built-in XML serialization
  • Globalization support
  • Group expressions for more complex scenarios
  • Match a list of values (i.e. A first name that matches any of: "John", "Jess")

What's New: Version 1.2.2

  • Added a shorthand function for operations that require no values (i.e. Operation.IsNull)
  • Added method to fetch the correct MatchType, when default is provided
  • More bug fixes. When one is solved another is found

Release Notes About Version 1.2.1

PLEASE NOTE THIS IS A BREAKING CHANGE I have left this in due to the updates being only a day apart

  • Simplified enumerables - To make it easier to type, and easier to read, I have simplified 2 enums. This is the "breaking change" I was refering to.
  • Operations & default match-types - Operations now have a default MatchType. This is the match-type that will be called by default.
  • Bug fixes and other minor improvements

For a full list of changes and previous revisions, see the Change Log
