我想獲得.NET客戶端庫代碼示例返回標準性能報告，但無法獲取代碼的功能。點擊AdWords.Examples.CSharp.OAuth測試頁上的「下載標準報告」按鈕時出現錯誤。Adwords API錯誤：ReportDownloadError.INVALID_VERSION。 C＃客戶端庫
的錯誤是如下：
System.Net.HttpWebRequest.GetResponse() +1399 Google.Api.Ads.AdWords.Util.Reports.ReportUtilities.DownloadReport(String downloadUrl, String postBody) in C:\Development\Projects\google.adwords.api\src\AdWords\Util\Reports\New\ReportUtilities.cs:183

我缺少什麼或者做錯了什麼？
我的主要目標是檢索我可以在網頁上顯示的XML Feed。
任何線索？
