如何序列化到现有的文件？ [英] How to serialize on to existing file?

问题描述

让说我有一个包含由BinaryFomatter序列化对象的文件。现在，我希望能够序列化另一个对象，并追加该上现有的文件。

Let say I have a file that contains a serialized object by BinaryFomatter. Now I want to be able to serialize another object and APPEND this on that existing file.

我该怎么办呢？

推荐答案

首先，如果你真正需要的是存储对象的数组 - 把它们放在一个容器和序列容器，正如前面所说的

First, if what you really need is to store an array of object - put them in a container and serialize the container, as said earlier.

现在，如果你真的想存储两个序列化对象级联单个文件：

Now, if you really want to store two serialized object in a single file concatenated:

我不知道这是可能的开箱即用，但你可以做两件事情。

I'm not sure that this is possible "out of the box", but you can do two things.

1. 使用，或创造你自己的半tar文件格式，在其中，你会写一个描述文件的内容的文件的开头小头（或结束）（＃对象和大小）。

1. Use, or invent your own semi-tar file format, in which you'll write a small header in the beginning (or end) of the file that describes the content of the file (#'objects, and sizes).

写C＃代码来检测每个序列化对象自己的开头和结尾。我不能完全肯定这是可能的。 这里是序列化格式的非官方的文档。它包含了头，但谁也不能保证，这头将不会出现在文件中。

Write a C# code to detect the beginning and end of each serialized object yourself. I'm not entirely sure it's possible. Here is a non-official documentation of the serialization format. It contains header, however there's no guarantee that this header won't appear in the file.
