C＃Assembly.Load与参考dll

Question

I am using the following code to load dlls at run time, and store their classes for later use.

public LoadDll(byte[] data)
{
    Assembly loadedAssembly = Assembly.Load(data);
    System.Type[] types = loadedAssembly.GetTypes();
    TypeRepo.Register(types);
}

and this works great, but if the dll I built has reference to another dll I get the error "The classes in the module cannot be loaded." when calling GetTypes().

How can I provide a specific file path to allow the loaded assembly accesses to a dependency on disk?

You should play with AppDomain.AssemblyResolve event

See what remarks section of the linked documentation points out:

It is the responsibility of the ResolveEventHandler for this event to return the assembly that is specified by the ResolveEventArgs.Name property, or to return null if the assembly is not recognized. The assembly must be loaded into an execution context; if it is loaded into the reflection-only context, the load that caused this event to be raised fails.

So you need to perform an Assembly.LoadFrom to return the whole Assembly instance by loading satellite assemblies from an arbitrary path defined by you in code.
