C# 已添加具有相同密钥的项。在c中反序列化对象时#

我正在反序列化一个对象，得到了标题错误。暗号

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);

返回行中出现错误

这是剪贴簿上的例外

如果你需要更多的信息，我可以提供。我想这是件简单的事，但我就是做不出来。当然，这可能与字典中的重复键有关，如果是这样的话，如何进一步深入了解这一点

提前谢谢你的帮助

尝试暂时序列化和反序列化单个成员，而不是整个类，以缩小哪个成员包含具有重复键的词典，以便您可以将注意力集中在较小的区域。

您是否在某处使用集合？

System.Collections.Generic.HashSet

和

Iesi.Collection.Generic

set类（O/R映射器NHibernate附带的类）都很麻烦。我切换到

IList来解决这个问题。
很抱歉，这与对象的序列化无关，但我当然是在创建新对象，然后将结构从字典更改为列表，然后在其他一些代码中错误地声明了对象的重复实例

对不起，错过了信息

Scott
有趣的想法，你到底要怎么做？此外，没有字典反序列化，这怎么可能？@Scott 1）当你序列化对象时，与其序列化你的SendWorldDataInstance，不如序列化你的SendWorldDataInstance.allPeople。反序列化时，将结果强制转换为LinkedList。对每个成员重复此操作，查看是否只有其中一个成员导致了错误。2） 必须是其中一个类的序列化逻辑在内部使用字典。问题是否只发生在一个特定的序列化数据集上，或者您可以通过创建一些新对象、序列化它，然后反序列化它来重现它？如果不能以这种方式重新创建，那么序列化的数据可能与当前版本的代码不同步。
