Valkyrie

Valkyrie is a simple set of data annotations and extension methods to help with validating your objects in .NET.

Basic Usage

For the most part, Valkyrie consists of DataAnnotations. To use Valkyrie, simply add the annotations to your properties as shown below:

public class MyClass { [Cascade] public MyOtherClass ItemA { get; set; } [Between("1/1/1900", "1/1/2100")] public DateTime ItemB { get; set; } [Contains("A")] public List<string> ItemC { get; set; } }

The System.ComponentModel.DataAnnotations.Validator class will automatically pick up these annotations when validating your object. Additionally, there are a couple of extension methods added to simplify object validation:

var results = new List<ValidationResult>(); bool didItWork = MyObject.TryValidate(results);

And:

MyObject.Validate();

The TryValidate method returns a list of validation results, while the Validate method throws a ValidationException if there are any issues with validating your object.
