＆是什么QUOT;数据视图没有标示在System.Data这＆QUOT为可序列化;意思？ [英] What does "DataView is not marked as serializable in System.data" mean?

问题描述

当我存储数据视图在ViewState中，.NET显示错误数据视图没有标记为System.Data这可序列化的，但是当我将它存储在会话，然后它完美？
背后是什么原因？其是未标记为其他对象
序列化？

When I store dataview in viewstate,.net shows the error "Dataview is not marked as serializable in system.data but when I store it in session, then it works perfectly? What is the reason behind it?? Which are the other objects that are not marked as "serializable " ?

推荐答案

这意味着该对象要存储（的数据视图）没有打上的 SerializableAttribute 。

It means that the object you want to store (DataView) isn't marked with a SerializableAttribute.

现在，你得到这个错误与ViewState的，而不是与会话的原因是因为ViewState是的总是的序列化，但是这并不一定会期如此。 在进程会话存储在服务器的内存中，并且不需要序列化。 SQLServer的会话必须序列存储在数据库中。

Now, the reason you're getting this error with ViewState and not with Session is because the ViewState is always serialized but that's not necessarily true of Session. In-Process sessions are stored in the server's memory and require no serialization. SQLServer sessions have to be serialized for storage in a database.

所以，任何时候你要存储在ViewState中的对象（或连载的会议），它必须被打上的 SerializableAttribute 。

So, anytime you want to store an object in the ViewState (or a serialized Session), it must be marked with a SerializableAttribute.
