起始頁面為Login.aspx，固定調試端口為49441。需要配合自己淘寶開放平臺的應用的回調頁面URL來調整。
ashx代碼：
（說明：代碼中ITopClient為淘寶接口TopSdk.dll中的類，此例子使用的ItemsOnsaleGetRequest是用于獲取銷售中的商品，response.Body是獲取到的數據信息）
public class OnsaleGet : IHttpHandler
{</p><p> public void ProcessRequest(HttpContext context)
{
context.Response.ContentType = "text/plain";
ITopClient client = new DefaultTopClient(Config.ServerURL, Config.Appkey, Config.Secret);</p><p> ItemsOnsaleGetRequest req = new ItemsOnsaleGetRequest();
req.Fields = "approve_status,num_iid,title,nick,type,cid,pic_url,num,props,valid_thru,list_time,price,has_discount,has_invoice,has_warranty,has_showcase,modified,delist_time,postage_id,seller_cids,outer_id";
ItemsOnsaleGetResponse response = client.Execute(req, Config.Top_session);</p><p>
if (response.IsError)

前端SL獲取數據信息的方法
void GetList()
{
string absolutePath = HtmlPage.Document.DocumentUri.AbsoluteUri;
string address = absolutePath.Substring(0, absolutePath.LastIndexOf('/'))
+ "/TaoBaoHandler/OnsaleGet.ashx";</p><p> Uri uri = new Uri(address);</p><p> WebClient client = new WebClient();
client.DownloadStringCompleted += (sender, e) =>
{
if (e.Error == null)
{
System.Xml.Linq.XElement.Parse(e.Result);//字符串轉為xml
ItemsOnsaleGetResponse list = SerializeHelper.DeserializeFromString<ItemsOnsaleGetResponse>(e.Result);//反序列化
if (list != null)
{
if (list.Items != null && list.Items.Count > 0)
{
MessageBox.Show(list.Items[0].NumIid.ToString());
}
}
else
{
}
}
else
{
MessageBox.Show(e.Error.Message);
}
};
client.DownloadStringAsync(uri);
}
SerializeHelper
序列化部分是自定義的一個類
public class SerializeHelper
{
private SerializeHelper() { }</p><p> #region Serialize</p><p> /// <summary>

public static string Serialize<T>(T data)
{
try

var serializer = new XmlSerializer(typeof(T));</p><p> XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
ns.Add("", "");
XmlWriterSettings writerSettings = new XmlWriterSettings();
writerSettings.OmitXmlDeclaration = true;
StringWriter stringWriter = new StringWriter();
using (XmlWriter xmlWriter = XmlWriter.Create(stringWriter, writerSettings))
{
serializer.Serialize(xmlWriter, data, ns);
}
string xmlText = stringWriter.ToString();</p><p> return xmlText;
}
catch (InvalidOperationException ex)
{
if (ex.Message != "")

淘寶相關的數據類型
TopModels模塊中的ItemsOnsaleGetResponse,Item,ItemImg,Location等這些實體是從TopSdk.dll中找到相應的定義粘貼出來供Silverlight下使用的。如圖
web.config中的配置
配置沙箱環境和正式環境的選擇，以及AppKey和AppSecret
<appSettings>
<!--IsSandBox 1=沙箱開啟 0=非沙箱(正式環境) -->
<add key="SandBox" value="1"/>
<!--應用 信息-->
<add key="AppKey" value="1012596959"/>
<add key="AppSecret" value="sandboxc5928dd8d1cfa3bb4f7d87e33"/></p><p> </appSettings>
另外，web中的那些Client.cs和Config.cs則是從淘寶示例Demo中來的。
最終數據的獲取如下：
