namespace ConsoleApplication
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine(GetType("int[,][,][][,][][]"));
            Console.WriteLine(GetType("Activator"));
            Console.WriteLine(GetType("List"));
        }

        private static Type GetType(string type)
        {
            var engine = new ScriptEngine();
            new[] { "System" }
                .ToList().ForEach(r => engine.AddReference(r));
            new[] { "System", "System.Collections.Generic" }
                .ToList().ForEach(ns => engine.ImportNamespace(ns));
            return engine
                .CreateSession()
                .Execute("typeof(" + type + ")");
        }
    }
}
