如何在一个字节数组之间对一个装配对象进行序列化/反序列化 [英] how to serialize/deserialize an assembly object to and from a byte array

问题描述

假设通过
编译代码字符串在内存中创建一个（可执行）程序集。然后，我想将此程序集
对象序列化为字节数组，然后将其存储在数据库中。然后，稍后我想从数据库中检索
并将字节数组
反序列化为程序集对象，然后调用程序集的条目
点。

Let's say a create an (executable) assembly in memory by compiling a code string. Then I want to serialize this assembly object into a byte array and then store it in a database. Then later on I want to retrieve the byte array from the database and deserialize the byte array back into an assembly object, then invoke the entry point of the assembly.

起初，我只是想像.net中的任何其他简单对象一样进行此序列化，但是显然，它不适用于汇编对象。程序集对象包含一个名为GetObjectData的方法，该方法获取重新实例化程序集所需的序列化数据。因此，对于如何将所有这些组合到我的场景中，我有些困惑。

At first I just tried to do this serialization like I would any other simple object in .net, however apparently that won't work with an assembly object. The assembly object contains a method called GetObjectData which gets serialization data necessary to reinstantiate the assembly. So I'm somewhat confused as to how I piece all this together for my scenario.

答案只需要显示如何获取组装对象，并将其转换为字节数组，将其转换回一个程序集，然后在反序列化的程序集上执行entry方法。

The answer only needs to show how to take an assembly object, convert it into a byte array, convert that back into an assembly, then execute the entry method on the deserialized assembly.

推荐答案

一个程序集更方便地表示为二进制dll文件。如果您想到的是 ，其余的问题就会消失。具体来说，请查看 Assembly.Load（byte []）进行 loading 和 Assembly 从二进制。要将其写入为二进制文件，请使用 CompileAssemblyFromSource 并查看结果的 PathToAssembly -然后是 File.ReadAllBytes（path）从文件中获取二进制文件。

An assembly is more conveniently represented simply as a binary dll file. If you think of it like that, the rest of the problems evaporate. In particlar, look at Assembly.Load(byte[]) for loading an Assembly from binary. To write it as binary, use CompileAssemblyFromSource and look at the result's PathToAssembly - then File.ReadAllBytes(path) to obtain the binary from the file.
