我得到这个异常“二进制流'0'不包含有效的BinaryHeader。可能的原因是无效的流或序列化和反序列化之间的对象版本更改。”。我正在寻找有关此异常的解决方案 2 天现在没有成功。我尝试了（我认为）everthing。请问有人可以看看下面的代码吗？错误在哪里？
谢谢。
private player ByteArrayToPlayer(byte[] temp)
{
try
{
MemoryStream objectStream = new MemoryStream(temp);
IFormatter BinaryFormatter
= new BinaryFormatter();
objectStream.Position =0;
return (player)BinaryFormatter.Deserialize(objectStream); <--- get exception
}
catch (Exception ex)
{

}
return null;
}
private byte[] PlayerToByteArray(player o)
{
try
{
objectStream = new MemoryStream();
IFormatter BinaryFormatter
= new BinaryFormatter();
BinaryFormatter.Serialize(objectStream, o);
objectStream.Seek(0, SeekOrigin.Begin);
return objectStream.ToArray();
}
catch (Exception ex)
