FEVOR is an abbreviation for Fluent Extensible Validator and it’s a .NET validation library with lots of features that simplify the validation process in development by abstracting away the complex logic of conditional statements.
- it can be used on any .NET project
- removes conditional statements clutter by making use of a fluent syntax;
- no need to learn any attributes or interfaces to extend it (it’s all based on extension methods);
- makes validation code readable even for non-developers, making it easy to maintain it;
- contains type-specific validation rules, but also generic rules that can be used on any type;
- gives you two options of extending it;
- has a built-in system for failure handling;
- choose from four types of warning methods, or use different ones on each validation group;
- has full support for NULL values/objects;
- has built-in error messages that can be easily overridden with your own;
- has a rich set of validation rules for the most common needs of a developer.
Included in the package
- The library’s source code which is heavily documented using XML tags;
- A WinForms demo application;
- Full API documentation in HTML and PDF format, with examples;
- A complete PDF tutorial with 3 levels full of code samples, explaining every feature of this library;
- A diagram exposing every member of this library.
- .NET Framework 4.0;
- Works on any type except dynamic types.
Here’s a quick sample code to give you an idea of how FEVOR will enhance your validation process:
"abcdef".Check("s") .IsNotNull() .IsLongerThan(1, "string too short") .IsAlpha("the string should have only letters!") .IsValidHexColor("this is not a valid HEX color"); n.Check("n").IsInRange(-10,10).IsGreaterThan(0);
