Finding objects that implement interface from loaded assembly -how to compare types?

Question

I have class that will load all assemblies in a directory and then get all the types an see if they implement an interface. I cannot get the type comparison to work. In the

OK - this gave me the answer: invalidcastexception-when-using-assembly-loadfile

Here is the updated class:

public class PluginLoader
{
    public static T[] GetInterfaceImplementor(string directory)
    {
        if (String.IsNullOrEmpty(directory)) { return null; } //sanity check

        DirectoryInfo info = new DirectoryInfo(directory);
        if (!info.Exists) { return null; } //make sure directory exists

        var implementors = new List();

        foreach (FileInfo file in info.GetFiles("*.dll")) //loop through all dll files in directory
        {
            Assembly currentAssembly = null;
            try
            {
                var name = AssemblyName.GetAssemblyName(file.FullName);
                currentAssembly = Assembly.Load(name);
            }
            catch (Exception ex)
            {
                continue;
            }

            currentAssembly.GetTypes()
                .Where(t => t != typeof(T) && typeof(T).IsAssignableFrom(t))
                .ToList()
                .ForEach(x => implementors.Add((T)Activator.CreateInstance(x)));
        }
        return implementors.ToArray();
    }
}
