Problem with Fedex Address Verification Web Reference

Question

I'm trying to get the sample FedEx Address Verification application to work in C#. After contacting my FedEx technical contact and having him activate Address Verification on my test account (apparently it is considered an advanced service that requires additional permissions) I was able to compile and run the example application.

However, I wasn't getting quite the results I expected given the settings...

request.Options.ConvertToUpperCase = true;
request.Options.CheckResidentialStatus = true;

Based on these flags, I expected to have the address come back in upper case, and to be able to check the Residential or ResidentialStatus properties to determine commercial vs residential. Neither were occuring.

So I installed Fiddler to see the exact SOAP exchange that was taking place and found that the outbound Options tag was not populating except for one property, MaximumNumberOfMatches.

Is there something I should check for in the Reference.cs file that is created by Visual Studio? I didn't see anything out of the norm, but something is happening that is preventing the serialization of some of the properties.

--Edit--

Updated my code as per the suggestion below. Unfortunately, it still only populates 2 of the options parameters. I've included the C# settings code and the outbound/inbound SOAP request below. Can anyone think of a reason the rest of the options are not being sent in the SOAP request?

AddressValidationRequest request = new AddressValidationRequest();
            //
            request.WebAuthenticationDetail = new WebAuthenticationDetail();
            request.WebAuthenticationDetail.UserCredential = new WebAuthenticationCredential();
            request.WebAuthenticationDetail.UserCredential.Key = "XXX-KEY-XXX"; // Replace "XXX" with the Key
            request.WebAuthenticationDetail.UserCredential.Password = "XXX-PWD-XXX"; // Replace "XXX" with the Password
            //
            request.ClientDetail = new ClientDetail();
            request.ClientDetail.AccountNumber = "XXX-ACCT#-XXX"; // Replace "XXX" with client's account number
            request.ClientDetail.MeterNumber = "XXX-MTR#-XXX"; // Replace "XXX" with client's meter number
            //
            request.TransactionDetail = new TransactionDetail();
            request.TransactionDetail.CustomerTransactionId = "***Address Validation v2 Request using VC#***"; // This is just an echo back 
            //
            request.Version = new VersionId(); // Creates the Version element with all child elements populated
            //
            request.RequestTimestamp = DateTime.Now;
            //
            request.Options = new AddressValidationOptions();
            request.Options.CheckResidentialStatus = true;
            request.Options.CheckResidentialStatusSpecified = true;
            request.Options.VerifyAddresses = true;
            request.Options.MaximumNumberOfMatches = "5";
            request.Options.StreetAccuracy = AddressValidationAccuracyType.MEDIUM;
            request.Options.DirectionalAccuracy = AddressValidationAccuracyType.MEDIUM;
            request.Options.CompanyNameAccuracy = AddressValidationAccuracyType.MEDIUM;
            request.Options.ConvertToUpperCase = true;
            request.Options.RecognizeAlternateCityNames = true;
            request.Options.ReturnParsedElements = true;
            //
            request.AddressesToValidate = new AddressToValidate[2];
            request.AddressesToValidate[0] = new AddressToValidate();
            request.AddressesToValidate[0].AddressId = "Kimmel";
            request.AddressesToValidate[0].Address = new Address();
            request.AddressesToValidate[0].Address.StreetLines = new String[1] { "425 Morningside Dr" };
            request.AddressesToValidate[0].Address.City = "Deerfield";
            request.AddressesToValidate[0].Address.PostalCode = "53531";
            request.AddressesToValidate[0].Address.CountryCode = "US";
            //
            request.AddressesToValidate[1] = new AddressToValidate();
            request.AddressesToValidate[1].AddressId = "WD";
            request.AddressesToValidate[1].Address = new Address();
            request.AddressesToValidate[1].Address.StreetLines = new String[1] { "2830 Progress Rd" };
            request.AddressesToValidate[1].Address.PostalCode = "53716";
            request.AddressesToValidate[1].CompanyName = "Wingra Direct";

Answer 1

It appears that on option is ignored unless you also set the optionSpecified flag to true also.

Here is my new options code that works - the key being that you need to add the Options.(property)specified = true for each one you want:

    request.Options = New AddressValidationOptions()
    request.Options.CheckResidentialStatus = True
    request.Options.CheckResidentialStatusSpecified = True
    request.Options.VerifyAddresses = True
    request.Options.VerifyAddressesSpecified = True
    request.Options.MaximumNumberOfMatches = 5
    request.Options.StreetAccuracy = AddressValidationAccuracyType.MEDIUM
    request.Options.DirectionalAccuracy = AddressValidationAccuracyType.MEDIUM
    request.Options.CompanyNameAccuracy = AddressValidationAccuracyType.MEDIUM
    request.Options.ConvertToUpperCase = True
    request.Options.ConvertToUpperCaseSpecified = True
    request.Options.RecognizeAlternateCityNames = True
    request.Options.RecognizeAlternateCityNamesSpecified = True
    request.Options.ReturnParsedElements = True
    request.Options.ReturnParsedElementsSpecified = True

Answer 2

I was unable to get the API working so I ended up manually coding the handling of SOAP requests and responses. Aside from the API not properly setting all the flags, I also found out that the FedEx DEV server was not returning the Residential Status, regardless of what the options were (confirmed by our FedEx Web Services contact). When we gained access to the production servers the new code worked like a charm.
