c++ callback 函数转 c#

[ludeli2004]

这是c++的回调函数：
// Callback functions.
void SetMessageProcessCallback(void* pUserObject_, void (*pfUserMessageProcessFunc_)(void*,AMC_MESG*));

__fastcall TFormProprioWare::TFormProprioWare(TComponent* Owner)
{
SetMessageProcessCallback((void *)this, &MesgProcessCallback);
}

void MesgProcessCallback(VOID* MyObjPtr, AMC_MESG* pclMesg_)
{
((TFormProprioWare*)MyObjPtr)->ProcessMesg(pclMesg_);
}

void TFormProprioWare::ProcessMesg(AMC_MESG *pclMesg_)
{}

下面是我转的代码：
[DllImport(Constant.Dllname_amc)]
public extern static void SetMessageProcessCallback(object sender, SetMessageCallback DelegateFunc);
[DllImport(Constant.Dllname_amc)]
public extern static void SetByteProcessCallback(object sender, SetByteCallback DelegateFunc);

public delegate void SetMessageCallback(object sender, ref AMC_MESG amc);
public delegate void SetByteCallback(object sender,byte ucByte);

SetMessageCallback callback1 = ProcessCallback.MesgProcessCallback;
SetByteCallback callback2 = ProcessCallback.ByteProcessCallback;

SetMessageProcessCallback(this, callback1);
SetByteProcessCallback(this, callback2);

public static void MesgProcessCallback(object sender, ref AMC_MESG amc)
{}
public static void ByteProcessCallback(object sender,byte ucByte_){}
可当控件的属性被修改时，这两个回调函数MesgProcessCallback 和 ByteProcessCallback 并不执行，请高手帮忙。
我想是不是动态库Constant.Dllname_amc没有被倒入内存中，所以它里面的线程没有启动的原因？？？
