Question

I am consuming a web service from a third party site. I have the type and method in the wsdl file called GetItemAvailable. When i consume and execute the service it returns a SOAP array (defined in the wsdl as ItemsArray).
The porblem is, i’m not sure what type i need to use to get to the information. here is my code:

GetItemAvailable.GetItemAvailable gia = new GetItemAvailable.GetItemAvailable();
ItemsArray ia = new ItemsArray();
ia = (gia.CallGetItemAvailable("1088507721", "9780842387491"));
string sttest = ia.id[1].ToString();

The error always says that ia.id is null

what am i doing wrong? i’m not very familiar with SOAP.
Here is the wsdl:

Answer 1

I got the issue resolved by writting a new class to wrap around the WSDL file.
Guess i should have just done this in the first place.
Thanks for all the help guys!!!

 public class STLItemAvailable
    {
        private string _itemNumber;
        public string ItemNumber
        {
            get
            {
                return _itemNumber;
            }
        }

        private int _tnOnHand;
        public int TNOnHand
        {
            get
            {
                return _tnOnHand;
            }
        }

        private int _tnOnOrder;
        public int TNOnOrder
        {
            get
            {
                return _tnOnOrder;
            }
        }

        private DateTime _tnOrderETA;
        public DateTime TNOrderETA
        {
            get
            {
                return _tnOrderETA;
            }
        }

        private int _nvOnHand;
        public int NVOnHand
        {
            get
            {
                return _nvOnHand;
            }
        }

        private int _nvOnOrder;
        public int NVOnOrder
        {
            get
            {
                return _nvOnOrder;
            }
        }

        private DateTime _nvOrderETA;
        public DateTime NVOrderETA
        {
            get
            {
                return _nvOrderETA;
            }
        }

        public STLItemAvailable()
        {
            //
            // TODO: Add constructor logic here
            //
        }

        public STLItemAvailable(string APIKey, string ItemNumber)
        {
            GetItemAvailable gia = new GetItemAvailable();
            ItemsArray ia = gia.CallGetItemAvailable(APIKey, ItemNumber);

            XmlElement[] XEArray = ia.Any;
            XmlNode n = XEArray[0];

            int testn = 0;
            DateTime testd;

                    case "item_id":
                        this._itemNumber = xn.InnerText;

                        int.TryParse(xn.InnerText, out testn);
                        this._tnOnHand = testn;
                        break;

                        this._tnOnOrder = testn;
