affiliate window merchant api in asp.net c#

My codes are



private void GetAW()
{
const string affiliateApiPassword = "48characterpassword";

// NB there are keys for datafeed, productservice and affiliateservice so make sure you pick the right one for the right service

var aw = new ApiService
{
UserAuthenticationValue = new UserAuthentication
{
iId = int value,
sPassword = affiliateApiPassword,
sType = UserType.affiliate
}
};

// obvious fill in your dates etc...
var transactionList = new getTransactionList
{
dStartDate = new DateTime(2013, 10, 03, 0, 0, 0, 0),
dEndDate = new DateTime(2013, 10, 07, 23, 59, 59, 999),
sDateType = DateType.transaction

};

// bit of XML craziness - because we have a namespace.. we have to create a document so that we can create a name space manager
var document = new XmlDocument();

// then add the namespace manager
var manager = new XmlNamespaceManager(document.NameTable);

// then add the aw namespace
manager.AddNamespace("ns1", "http://api.affiliatewindow.com/");

// Get the list of transactions
getTransactionListResponse response = aw.getTransactionList(transactionList);

// Did we get a resposnse
if (response != null)
{
// Have we got a transaction list returned?
if (response.getTransactionListReturn != null)
{
// yes, so Get the XML element array
ArrayOfTransaction z = response.getTransactionListReturn;
foreach (XmlElement thunk in z.Any)
{
// These are the transaction data type fields
// iId

XmlNode xmlNode = thunk.SelectSingleNode("//ns1:iId", manager);
if (xmlNode != null)
{
string aa = xmlNode.InnerText;
}



// up to you from this point you can select which fields you want to deal with etc..
// sStatus
// sType
// sIp
// bPaid
// iPaymentId
// sDeclinedReason
// iMerchantId
// fSaleAmount
// fCommissionAmount
// dClickDate
// dTransactionDate
// dValidationDate
// sClickRef
// sSearchSiteName
// sSearchSiteKeyword
// aTransactionParts (node with other items in it)
xmlNode = thunk.SelectSingleNode("//ns1:aTransactionParts", manager);
if(xmlNode!=null)
{
// This is another node that contains a ns1:TransactionPart
// sCommissionGroupName
// fSaleAmount
// iCommission
// sCommissionType
string aa = xmlNode.InnerXml;

// SelectSingleNode or ignore - up to what you want to do of course
}

}
}
