c# - 已添加具有相同 key 的项目。在 C# 中反序列化对象时

Question

我正在反序列化一个对象，并收到标题错误。代码如下

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);

返回行上出现错误。

这是剪贴板异常

public Socket Socket;

public List<byte> TransmissionBuffer = new List<byte>();

public byte[] buffer = new byte[5500000];

如果您需要更多信息，我可以提供。我希望这很简单，但我就是无法解决。当然，这可能与字典中的重复键有关，如果是的话，如何进一步深入找出这一点。

感谢您提前提供的所有帮助。

你在某处使用集合吗？两者都是System.Collections.Generic.HashSet<T>和 Iesi.Collection.Generic设置类(那些与 O/R 映射器 NHibernate 一起提供的类)很麻烦。我切换到 IList<T>解决该问题。
