介紹：本文介紹通過API下載亞馬遜平臺的訂單。

第一步：下載亞馬遜平臺的客戶端庫，網址：https://developer.amazonservices.com.cn/doc/orders/orders/v20110101/cSharp.html，解壓后，重新生成DLL

第二步：在自己的項目中引用DLL，撰寫調用代碼。訂單下載涉及兩個接口：ListOrders和ListOrderItems

下面直接上代碼：

參數：

//賣家編號

publicstringMerchant="XXX";
//商城編號
publicstringMarketplaceID="XXX";
//AWS訪問密鑰
publicstringAWSAccessKeyID="XXX";
//密鑰
publicstringKey="XXX";
publicstringapplicationName="XXX";
publicstringapplicationVersion="1.0";
