Silverlight 4

The entire Simple.Validation library has been compiled for Silverlight and included in the NuGet package.

Conditional Property Validators

An If() method has been applied to the following property validators:

• EnumerablePropertyValidator
• RangePropertyValidator
• ReferencePropertyValidator
• StringPropertyValidator

When If() is called with the required Predicate, the validator will only apply when the condition specified by the Predicate is met.

        [Test]
        public void If_PredicateIsFalse_ShouldNotValidate()
        {
            // Arrange
            var validator = Properties<Employee>
                .For(e => e.Age)
                .GreaterThanOrEqualTo(18)
                .If(e => e.Age != -1)
                ;

            // Act
            var employee = new Employee()
            {
                Age = -1
            };
            var results = validator.Validate(employee);

            // Assert
            Assert.That(results, Is.Empty);

        }
