i do this code :
List<Verifier> verifiers = new List<Verifier>();
verifiers.Add(GetPersonelUniqVerifier());
VerifierContext pVerifierContext=new VerifierContext(VerifierOnErrorMode.Continue, ?) ;//I put null
VerifierResultCollection results =
mPersMgr.VerifierEngine.Execute(DetailInEdit, verifiers, pVerifierContext);//10 overload
then run and tis error :
{"Object reference not set to an instance of an object."}
how to use 10 overload of how to use 10 overload of VerifierEngine.Execute
public static Verifier GetPersonelUniqVerifier()
{
// ToDo: localize description
string description = "کد پرسنلی نباید تکراری باشد.";
DelegateVerifier<KarkardDetailTB> v =
new DelegateVerifier<KarkardDetailTB>(description, PersonelUniqVerifierCondition);
v.AddTriggers(Descriptors.MazayaID.Name);
v.ExecutionModes = VerifierExecutionModes.InstanceAndOnPostsetTriggers;
return v;
}
public static VerifierResult PersonelUniqVerifierCondition(
KarkardDetailTB pMjd, TriggerContext pTriggerContext, VerifierContext pVerifierContext)
{
if (pTriggerContext != null &&
// We are not checking the proposed value because don't expect to call it preset
pTriggerContext.Timing == TriggerTiming.Preset)
{
throw new VerifierException("BornBeforeHired verifier not implemented for Preset");
}
if (pMjd.PersonID == KarkardDetailTB.GetPersonelID(pMjd.PersonID.Value,pMjd.KarkardID.Value))
if (pMjd.Id != KarkardDetailTB.GetID(pMjd.PersonID.Value,0, false, pMjd.KarkardID.Value, KarkardTypeEnumTB.Mabani().EnumValue))
return new VerifierResult(false);
return new VerifierResult(true);
}

i use verifierEngine.Execute(1 overload ) and no error but i need 2 getverifier methode
in entity
[VerifierProvider]
public static IEnumerable<Verifier> GetVerifiers1(Object pVerifierProviderContext)
{
List<Verifier> verifiers = new List<Verifier>();
verifiers.Add(Get1());
verifiers.Add(Get2());
return verifiers;
}
public static IEnumerable<Verifier> GetVerifiers2(Object pVerifierProviderContext)
{
List<Verifier> verifiers = new List<Verifier>();
verifiers.Add(Get3());
return verifiers;
}

hi , thx GregD i solve this problem with this code:
mPersMgr.VerifierEngine.AddVerifier(get1());
mPersMgr.VerifierEngine.AddVerifier(get2());
if(condition)
mPersMgr.VerifierEngine.AddVerifier(get3());
VerifierResultCollection results =
mPersMgr.VerifierEngine.Execute(DetailInEdit);//1 overload
