System.NullReferenceException when using WSDL in C# SOAP Request

Question

Another Similar But cant figure out Problem Tried the answer which worked for previous question in this same post, Which was for Arrays. Over here it is lookups and iv tried the below but its still not working. Iv also tried

 createCustomerRequest.CustomerDetails.Title[0].Code[0] = cloneTitleCode[0];

All the [0] iv switched them around and took them off too and tried all the combinations still doesnt work.

 //Security settings to match server using this line: -
 Dsoapui.https.protocols=SSLv3,TLSv1.2 ...
 BasicHttpsBinding httpsBinding = new 
 BasicHttpsBinding(BasicHttpsSecurityMode.Transport);

 //Using the security settings to create the client which will let us send/recieve the requests...
            CustomerServiceClient soapClient = new CustomerServiceClient("BasicHttpsBinding_ICustomerService");

            //Set credentials for the client...
            soapClient.ClientCredentials.UserName.UserName = username;
            soapClient.ClientCredentials.UserName.Password = password;

            //Create instances of requesting and recieving data from the server for customerDetails...
            CreateCustomer createCustomer = new CreateCustomer();
            CreateCustomerRequest createCustomerRequest = new CreateCustomerRequest();
            CreateCustomerResponse createCustomerResponse = new CreateCustomerResponse();

            //Set customer details request (so whatever will be included in the request to recieve the info)...
            createCustomerRequest.UserName = username;
            createCustomerRequest.Password = password;
            createCustomerRequest.SystemToken = "2fa192c3-1215-41f9-be71-2ba6e279494e";

            //Get current time to generate unique customer number...
            string currentTime = DateTime.Now.ToLongTimeString();
            string cleanTime = Regex.Replace(currentTime, "[^A-Za-z0-9 ]", "");

            //For WSDL arrays create the array and instance then use it like below...
            createCustomerRequest.CustomerDetails.Title = new CustomerServiceWSDL.LookupItem();
            createCustomerRequest.CustomerDetails = new CreateCustomer();
            createCustomerRequest.CustomerDetails.CustomerNumber = "001" + cleanTime;
            createCustomerRequest.CustomerDetails.FirstName = cloneFirstName;
            createCustomerRequest.CustomerDetails.Surname = cloneSurName;

            createCustomerRequest.CustomerDetails.Title.Code = cloneTitleCode;

That's cause purchaseOnHoldSetRequest.AdditionalDetail is an Array type (mostly, from your posted code) which you haven't initialized and trying to set an item in index 0 saying purchaseOnHoldSetRequest.AdditionalDetail[0].Description which will bound to throw NullRefException

Per your WSDL, the said property is array of AdditionalDetails class as seen below

[System.Runtime.Serialization.DataMemberAttribute()]
public Account_Status.ServiceReference2.AdditionalDetail[] AdditionalDetail {
    get {
        return this.AdditionalDetailField;
    }
    set {
        if ((object.ReferenceEquals(this.AdditionalDetailField, value) != true)) {
            this.AdditionalDetailField = value;
            this.RaisePropertyChanged("AdditionalDetail");
        }
    }
}

Thus you need to initialize it first

    purchaseOnHoldSetRequest.UserName = "username";
    purchaseOnHoldSetRequest.Password = "password";
    purchaseOnHoldSetRequest.SystemToken = "systemtoken";
    purchaseOnHoldSetRequest.AgreementReference = customerAgreementNumberComboBox.Text;

purchaseOnHoldSetRequest.AdditionalDetail = new AdditionalDetail[3]; // here

And then access it likewise you are doing

   purchaseOnHoldSetRequest.AdditionalDetail[0] = new AdditionalDetail();
   purchaseOnHoldSetRequest.AdditionalDetail[0].Description = "1";
