Delizious Filtering

What?

Delizious Filtering is a flexible and easy to use .NET library entirely written in C# that simplifies matching of values as well as filtering of collections. It comes with a fluent and straightforward API and lets you define matches (conditions) the easy way.

Features

Delizious Filtering provides the following features:

• Intuitive and fluent API design
• Implementation of matches is based on immutability and value semantics
• Enables separation of object graph construction (define matches) and application logic (match matches) as discussed here (by the way a very interesting article about writing testable code!)
• Enables custom matches

Upcoming features:

• Simplified use with LINQ

Matches

Match	What
Always	Succeeds always no matter what value is matched
Never	Succeeds never no matter what value is matched
Null	Succeeds when a value is a null reference
NotNull	Succeeds when a value is not a null reference
Same	Succeeds when a value represents the same instance the match was initialized with
NotSame	Succeeds when a value does not represent the same instance the match was initialized with
Equal	Succeeds when a value is equal to the instance the match was initialized with
NotEqual	Succeeds when a value is not equal to the instance the match was initialized with
GreaterThan	Succeeds when a value is greater than the instance the match was initialized with
GreaterThanOrEqualTo	Succeeds when a value is greater than or equal to the instance the match was initialized with
LessThan	Succeeds when a value is less than the instance the match was initialized with
LessThanOrEqualTo	Succeeds when a value is less than or equal to the instance the match was initialized with
All	Succeeds when a value matches all of the given matches
Any	Succeeds when a value matches any of the given matches
Except	Succeeds when a value matches none of the given matches
Custom	Succeeds when a value matches according to the given custom match
