Arrays in webservices - Object reference not set to an instance of an object

I am sending soap messages that contains arrays. I have problems with arrays in my code. It gives the above errors, I've looked everywhere, even wrote and rewrote my code over and over again but I can't seem to find where I am going wrong.

Would be so grateful if somebody can point me in the right direction:

UpdateRatePackages.IService.InventoryServiceClient isc = new UpdateRatePackages.IService.InventoryServiceClient();
    UpdateRatePackages.IService.UpdateRatePackagesRequest ureq = new UpdateRatePackages.IService.UpdateRatePackagesRequest();
    UpdateRatePackages.IService.UpdateRatePackagesOperationResponse ores = new UpdateRatePackages.IService.UpdateRatePackagesOperationResponse();

protected void Page_Load(object sender, EventArgs e) { SendSoapMessage(); }

protected void SendSoapMessage() {

        Int64 HID = 717759;
        Int64 HRID = 85264;
        int avail = 6;
       // RateDetails.AvailabilityApplicationType val  = RateDetails.AvailabilityApplicationType.SET;
       for (int i = 0; i < ureq.RatePackages.GetLength(0); i++)
        {
            ureq.RatePackages[i].RatePackageId = HRID;
            for (int j = 0; j < ureq.RatePackages[j].Rates.GetLength(0); j++)
            {
                ureq.RatePackages[i].Rates[j].Availability = avail;
                ureq.RatePackages[i].Rates[j].AvailabilityApplicationType = UpdateRatePackages.IService.AvailabilityApplicationType.SET;
                ureq.RatePackages[i].Rates[j].FromDate = Convert.ToDateTime("2012-03-21");
                ureq.RatePackages[i].Rates[j].ToDate = Convert.ToDateTime("2012-03-31");
            }

           // isc.UpdateRatePackages(request);

        }

Data Defined as in the webservice:

     public class UpdateRatePackagesRequest
    {
        public string Username;
        public string Password;
        public UpdateRatePackageRequest[] RatePackages;


    }

    public class UpdateRatePackageRequest
    {
        public Int64 RatePackageId;
        public RateDetails[] Rates;

    }


    public class RateDetails
    {
        public decimal Rate;
        public enum RateApplicationType { SET, INCREASE, DECREASE, INCREASE_PERCENT, DECREASE_PERCENT } ;
        public int Availability;
        public enum AvailabilityApplicationType { SET , INCREASE, DECREASE };
        public bool StopSell;
        public string Inclusions;
        public int MinimumNightStay;
        public DateTime FromDate;
        public DateTime ToDate;

    }



    public class UpdateRatePackageResult
    {
        public Int64 RatePackageId;
        public Boolean Success;
        public string Message;

    }

    public class UpdateRatePackagesResponse

    {
        public UpdateRatePackageResult[] Result;

    }

Is my problem in the arrays or does it have something to do with the soap message itself?

line where error is highlighted:

for (int i = 0; i < ureq.RatePackages.GetLength(0); i++)

Please help!

for (int i = 0; i < ureq.RatePackages.GetLength(0); i++)

If the error is happening there, then either ureq or RatePackages is null. Step through in the debugger and see which one is null. It does look like you're setting ureq, but you should check both anyway.
