Public Function New( _
   ByVal errorMessage As String, _
   ByVal verifierCondition As IdeaBlade.Validation.VerifierCondition(Of T) _
)

'Usage

errorMessage: Error message for failed verification
verifierCondition: Defines the verification to be performed

C#

private DelegateVerifier SampleDelegateVerifier() {
   // A simple example adding a delegate verifier for the Employee HireDate property.
   // This verifier could more easily be handled using a DateTimeRangeVerifier,
   // but is intended to show the parts to a DelegateVerifier.

   string errorMessage = "HireDate must be greater than MinValue";

   // Define the verification test. 
   VerifierCondition<Employee> condition = (emp, trigger, ctx) => {
     // Note when executed before the property is set that we must inspect the ProposedValue.
     DateTime? hireDate = (trigger.Timing == TriggerTiming.BeforeSet) ? (DateTime?) trigger.ProposedValue : emp.HireDate;
     return new VerifierResult(hireDate >= DateTime.Parse("1/1/2000"));
   };

   // Create the verifier.
   var v = new DelegateVerifier<Employee>(errorMessage, condition);

   // Add a trigger - here it's the HireDate property.
   v.AddTrigger(Employee.PropertyMetadata.HireDate.Name);

   return v;
