Saving an Assembly as a byte array suitable for Assembly.Load

I notice that Assembly.LoadFrom has the following overload

public static Assembly Load(
    byte[] rawAssembly
)

How do I save an assembly as a byte array in order to create it like this?

Context : I want to write a test harness that will ensure backward compatability of a service. I want to load canned versions of the client into my harness and call the service from many different versions. I think saving the old versions as byte[] would allow me to freeze them.

Like so:

byte[] assemblyBytes = File.ReadAllByes(assemblyPath);

NOTE that you will have to load dependent assemblies first.

If you have old versions as files (just as they were normally built) that's all you need. You can read those into a byte array (e.g. with File.ReadAllBytes) if you need to.

It sounds like you just need to keep the old binaries in source control.
