起始頁(yè)面為L(zhǎng)ogin.aspx，固定調(diào)試端口為49441。需要配合自己淘寶開(kāi)放平臺(tái)的應(yīng)用的回調(diào)頁(yè)面URL來(lái)調(diào)整。

（說(shuō)明：代碼中ITopClient為淘寶接口TopSdk.dll中的類(lèi)，此例子使用的ItemsOnsaleGetRequest是用于獲取銷(xiāo)售中的商品，response.Body是獲取到的數(shù)據(jù)信息）

淘寶相關(guān)的數(shù)據(jù)類(lèi)型
TopModels模塊中的ItemsOnsaleGetResponse,Item,ItemImg,Location等這些實(shí)體是從TopSdk.dll中找到相應(yīng)的定義粘貼出來(lái)供Silverlight下使用的。如圖
web.config中的配置
配置沙箱環(huán)境和正式環(huán)境的選擇，以及AppKey和AppSecret
<appSettings>
<!--IsSandBox 1=沙箱開(kāi)啟 0=非沙箱(正式環(huán)境) -->
<add key="SandBox" value="1"/>
<!--應(yīng)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(lái)的。
最終數(shù)據(jù)的獲取如下：
