从MemoryStream反序列化会在C＃中引发OutOfMemory异常 [英] Deserialize from MemoryStream throws OutOfMemory exception in C#

问题描述

这是C＃3.0 Winform问题。

This is a C# 3.0 Winform problem.

我想克隆一个大（实际上不是很大）的复杂对象。为了做到这一点，我将它序列化为MemoryStream并使用BinaryFormatter.UnsafeDeserialize（MemoryStream，null）方法来获取克隆的对象。在UnsafeDeserialize（）方法内部，始终会引发OutOfMemory异常。内存应该足够。

I want to clone a big(not very big actually), complicated object. To do it lazily, I seralize it to a MemoryStream and use BinaryFormatter.UnsafeDeserialize(MemoryStream, null) method to get the cloned object. Inside the UnsafeDeserialize() method, there is always an OutOfMemory exception thrown. The memory should be sufficient.

我读了一些有关.net的错误，但不确定是否是这种情况。

I read a bit about this as a .net bug but not sure whether it is the case here.

任何人都知道为什么会这样吗？是否有工作流程？谢谢。

Anyone has any idea why this is happening? Any workround? Thanks.

推荐答案

也许是一个愚蠢的问题，但是您还记得在反序列化之前将MemoryStream倒回到流的开头吗？

Perhaps a silly question but are you remembering to rewind the MemoryStream to the start of the stream before deserializing it?

它也可能有助于共享您的一些代码。

It might also help to share some of your code.
