具有相同鍵的項目已被添加。 在C＃中反序列化對象時

Question

我正在反序列化一個對象，但出現標題錯誤。 波紋管

byte[] dataBuffer = TransmissionBuffer.ToArray();
dataBuffer = Decompress(dataBuffer);
BinaryFormatter bin = new BinaryFormatter();
MemoryStream mem = new MemoryStream();
mem.Write(dataBuffer, 0, dataBuffer.Length);
mem.Seek(0, 0);

return (SendWorldData)bin.Deserialize(mem);

錯誤在返回線上。

這是剪貼板異常

如果您需要更多信息，我可以提供。 我希望這很簡單，但我無法解決。 當然，如果有的話，這可能與字典中的重復鍵有關。

感謝您提前提供的所有幫助。

Answer 1

您在某處使用集嗎？ System.Collections.Generic.HashSet<T>和Iesi.Collection.Generic集合類（隨O / R映射器NHibernate一起提供的集合類）都很麻煩。 我切換到IList<T>來解決此問題。

Answer 2

嘗試臨時序列化和反序列化單個成員而不是整個類，以縮小哪個成員包含具有重復鍵的字典，以便將注意力集中在較小的區域。

Answer 3

抱歉，但這與對象的序列化無關，但是我當然是在創建新對象，然后將結構從字典更改為列表，然后我重復了對象的實例，因為我在某些其他代碼中錯誤地聲明了它們。

對不起，小姐信息！
