用於C＃的YouTube GData API - 我在哪裏可以找到工作批量查詢的示例？

Question

我已經在網上搜索了幾天，但沒有成功，只是在使用C＃API尋找YouTube批量請求的示例。如此多的文檔已過時。

這些告訴我的XML應該是什麼樣子：

https://developers.google.com/gdata/docs/batch https://developers.google.com/youtube/2.0/developers_guide_protocol_batch_processing

，這是與谷歌電子表格的例子：

https://developers.google.com/google-apps/spreadsheets/#updating_multiple_cells_with_a_batch_request

雖然我可怕的關閉時間再次，我一直沒有達到那個輝煌的描述性GDataRequestException「執行請求批次失敗」的標記。

幫助！

終於破解了！

現在，這樣你就不必去通過相同的雙盲試驗&恐怖的經歷，我忍着：

using Google.GData.YouTube;

，僅供參考，這個帖子下面的批量要求XML的配置文件，它從很大不同其他樣品，但仍然像一個魅力：
