使用XmlSerializer序列化IntPtr [英] Serialize an IntPtr using XmlSerializer

问题描述

我想知道XmlSerializer实现为什么不支持IntPtr类型.当我尝试序列化包含IntPtr类型的字段的类时，序列化失败，告诉我不支持IntPtr，并忽略该成员.

要解决此问题，我将IntPtr值转换为Int64 ...，但这是一个好主意吗?就我所能想到的.具体来说，我需要序列化一个窗口句柄，该句柄在.NET Framework中键入IntPtr.我做对了吗?

解决方案

IntPtr不可序列化的原因是，将其从环境中删除时，它通常根本没有任何意义.

如果序列化窗口句柄，则只有在窗口仍存在的情况下在同一位置反序列化它，才有意义.如果您在其他计算机，其他应用程序中或在删除窗口后反序列化它，则该句柄没有任何意义.

因此，您可以将其转换为可序列化的类型，但是要确保在反序列化它时仍然有意义.

I'm wondering why the IntPtr type is not supported by the XmlSerializer implementation. When I try to serialize a class including a field of IntPtr type, the serialization fails telling me that IntPtr is not supported, and ignore that member.

To workaround this, I translate the IntPtr value to a Int64... but is it a good idea? It should be, as far I can think. In concrete, I need to serialize a window handle, which is typed IntPtr in .NET framework. Am I doing correct?

解决方案

The reason that an IntPtr is not serializable is that it generally doesn't make any sense at all when you remove it from it's environment.

If you serialize a window handle, it only makes sense if you deserialize it in the same spot, while the window still exists. If you deserialize it on a different computer, in a different application, or after the window is removed, the handle has no meaning.

So, you can cast it to a type that is serializable, but it's up to you to make sure that it still makes sense when you deserialize it.
