D3D9 Macro problem

[GoogleCodeExporter]

Hi.

Firstly sorry for my bad english : )

I'm using SlimDX June 2010. I'm working on my own big project and stucked with 
one problem. When i use EffectCompiler to call "CompileShader(...)", shaders 
compiles incorrect! I've spend about week to figuring out what caused  shader 
corruption - my HLSL code seems to be correct.

I googled my problem and found  code like that (for C++)

  // собираем макросы
  std::vector<D3DXMACRO> MacroVect;
  ShaderMacroContainer::DefinesMap::const_iterator macro_it = Desc.Macro.Defines.begin();
  while (macro_it != Desc.Macro.Defines.end())
  {
    D3DXMACRO NewDefine;
    NewDefine.Name = macro_it->first.c_str();
    NewDefine.Definition = macro_it->second.c_str();
    MacroVect.push_back(NewDefine);
    macro_it++;
  }
  D3DXMACRO EndDefine;
  EndDefine.Name = NULL;
  EndDefine.Definition = NULL;
  MacroVect.push_back(EndDefine)

so at the end of MACRO list we should add"null" element 
(  
  EndDefine.Name = NULL;
  EndDefine.Definition = NULL;
)

But if I'm trying to do that in C#:

macro[macro.Length - 1].Definition = null;
macro[macro.Length - 1].Name = null;

I'm catching this exception:

"Ссылка на строку не ссылается на экземпляр 
String.
Имя параметра: s"

 - something like:

"The reference to the string does not refer to an instance of String.
Parameter name: s "

You don't need to manually add the null macro at the end in SlimDX, as we do 
this for you. You should only need to pass the actual macros you want to use to 
Effect.FromMemory or whatever you are calling.
