C# snippet, based on the Powershell answers:

var modules = assembly.GetModules();
var kinds = new List();
var images = new List();
foreach (var module in modules)
{
    PortableExecutableKinds peKinds;
    ImageFileMachine imageFileMachine;
    module.GetPEKind(out peKinds, out imageFileMachine);

    kinds.Add(peKinds);
    images.Add(imageFileMachine);
}

var distinctKinds = kinds.Distinct().ToList();
var distinctImages = images.Distinct().ToList();
