CompileAssemblyFromSource + Obfuscation = don't work

我有工作compileassemblyfrom源代码。但是当我使用任何代码保护，如RedGate SmartAssembly或Themida它停止工作，我得到错误"无法加载文件或程序集或其依赖项之一"。你能帮我一下吗?

using System;
using System.CodeDom.Compiler;
using System.Reflection;
using Microsoft.CSharp;
namespace stringToCode
{
    public class Program
    {
        public static int q = 0;
        static void Main(string[] args)
        {
            try
            {
                string source = "namespace stringToCode { public class FooClass { public void Execute() { Program.q = 1; } } }";
                Console.WriteLine("q=" + q);
                using (var foo = new CSharpCodeProvider())
                {
                    var parameters = new CompilerParameters();
                    parameters.GenerateInMemory = true;
                    foreach (Assembly assembly in AppDomain.CurrentDomain.GetAssemblies())
                    {
                        try
                        {
                            string location = assembly.Location;
                            if (!String.IsNullOrEmpty(location))
                            {
                                parameters.ReferencedAssemblies.Add(location);
                            }
                        }
                        catch (NotSupportedException)
                        { }
                    }
                    var res = foo.CompileAssemblyFromSource(parameters, source);
                    var type = res.CompiledAssembly.GetType("stringToCode.FooClass");
                    var obj = Activator.CreateInstance(type);
                    var output = type.GetMethod("Execute").Invoke(obj, new object[] { });
                    Console.WriteLine("q=" + q);
                }
            }
            catch (Exception e)
            {
               Console.WriteLine(e.Message);;
            }
            Console.ReadLine();
        }
    }
}
