這裏是我使用的C＃的Facebook的SDK 6.8.0從的NuGet測試配料代碼：爲什麼Facebook發佈批次與GraphBatchException - ＃0失敗？
var client = new FacebookClient();
client.AppId = application.FacebookAppId;
client.AppSecret = application.FacebookAppSecret;
var batchedRequests = new List<FacebookBatchParameter>();
batchedRequests.Add(new FacebookBatchParameter()
{
HttpMethod = HttpMethod.Post,
Path = "2982XXXXXXXXXX001/feed",
Parameters = new Dictionary<string, object>
{
{"access_token", "CAAK9UGtbUaMBAKX..."},
{"message", "Check out our stuff at Google: " + DateTime.UtcNow.Ticks},
{"link", "http://www.google.com"}
}
});
batchedRequests.Add(new FacebookBatchParameter()
{
HttpMethod = HttpMethod.Post,
Path = "755XXXXXXXXXX21/photos",
Parameters = new Dictionary<string, object>
{
{"access_token", "CAAK9UGtbUaMBAA6..."},
{"message", "Lions, oh my! " + DateTime.UtcNow.Ticks},
{"url", "http://i.imgur.com/DVSsmpa.jpg"}
}
});
batchedRequests.Add(new FacebookBatchParameter()
{
HttpMethod = HttpMethod.Post,
Path = "2982XXXXXXXXXX001/feed", // Same as first
Parameters = new Dictionary<string, object>
{
{"access_token", "CAAK9UGtbUaMBAKX..."}, // Same as first
{"message", "Check out our stuff at Facebook: " + DateTime.UtcNow.Ticks},
{"link", "http://www.facebook.com"}
}
});
var batchedParams = new Dictionary<string, object>();
batchedParams.Add("access_token", defaultPage.PageAccessToken);
dynamic facebookResponse = client.Batch(batchedRequests.ToArray(), batchedParams);
如果我註釋掉三個batchedRequests.Add（）中的任何一個要求，它工作正常。
只有三者在一起纔會被打破。
這是我得到的錯誤：

的錯誤意味着你的批次不正確編碼/包/序列化 - 你調試嗎？ – Igy 2014-10-27 23:34:39
它一次只能運行一個或兩個記錄，但全部3個都會導致失敗。我不確定此時需要包裝什麼。 – Kcoder 2014-10-27 23:42:35
我懷疑這可能是FacebookClient.Batch（）方法如何處理請求的問題，但不幸的是，我沒有任何可見性來查看傳遞給Facebook的URL調用。 – Kcoder 2014-10-27 23:48:26
