You need to invoke CreateInstanceAndUnwrap
before your proxy object will execute in the foreign application domain.
class Program
{
static void Main(string[] args)
{
AppDomainSetup domaininfo = new AppDomainSetup();
domaininfo.ApplicationBase = System.Environment.CurrentDirectory;
Evidence adevidence = AppDomain.CurrentDomain.Evidence;
AppDomain domain = AppDomain.CreateDomain("MyDomain", adevidence, domaininfo);
Type type = typeof(Proxy);
var value = (Proxy)domain.CreateInstanceAndUnwrap(
type.Assembly.FullName,
type.FullName);
var assembly = value.GetAssembly(args[0]);
// AppDomain.Unload(domain);
}
}
public class Proxy : MarshalByRefObject
{
public Assembly GetAssembly(string assemblyPath)
{
try
{
return Assembly.LoadFile(assemblyPath);
}
catch (Exception)
{
return null;
// throw new InvalidOperationException(ex);
}
}
}
Also, note that if you use LoadFrom
you’ll likely get a FileNotFound
exception because the Assembly resolver will attempt to find the assembly you’re loading in the GAC or the current application’s bin folder. Use LoadFile
to load an arbitrary assembly file instead–but note that if you do this you’ll need to load any dependencies yourself.
