Reflection in D

thank you, the second method works perfectly.

I have one last problem, I start thread and in thread 
Protocol.GetInstance(id) return null while in main thread it 
works.

My class :

class ProtocolMessageManager
{
     private static TypeInfo_Class[uint] m_types;
	
     shared static this()
     {
         foreach(mod; ModuleInfo)
         {
	    foreach(TypeInfo_Class lc; mod.localClasses)
	    {
	        if(lc.base is typeid(NetworkMessage))
		{
		    NetworkMessage c = cast(NetworkMessage)lc.create();
		    ProtocolMessageManager.m_types[c.MessageId] = lc;
		}
	    }
	}
    }

    public static NetworkMessage GetInstance(uint id)
    {
        auto v = (id in ProtocolMessageManager.m_types);
        if (v !is null)
	return 
cast(NetworkMessage)ProtocolMessageManager.m_types[id].create();
        else
	return null;
     }
}
