pointer arrays

I'm not sure if I'm understanding this properly, i have the following in c++

Code:

---

void test1(byte* dcData,int x,int y)
{
  int startrow=0;
  int endrow=2;
  byte* data = dcData;
  byte* adjusteddata=data+startrow*x+startcol*y;
  for(int y=0;y<whatever;y++)
  {
      byte* dest=adjusteddata+x*y;
  }
}

---

I've done a conversion to c# but i think I may be interpreting it wrong??

Code:

---

public void test1(byte[] dcData,int x,int y)
{
  int startrow=0;
  int endrow=2;
  byte[] data = dcData;
  byte[] adjusteddata=data+startrow*x+startcol*y;
  for(int y=0;y<whatever;y++)
  {
      byte[] dest=adjusteddata+x*y;
  }
}

Seems like more of a C# forum question.

If you are changing it to c# method, then you will need to declare as unsafe, which basically means you code maybe executed depending upon the users machine you are running it on. If you start using c style types, then your code becomes less portable; which works against the .net framework. Its still a pile of toss anyway (well its ok i suppose), c++ will always live!

I suppose if you describe what you want to do, I could show you a way to implement it properly in C#. However, the piece you have given doesn't do anything usefull and I won't take guesses what it should do.

Give a clear description what you want the function to do and what parameters you want to give and we'll find a nice implementation.

I think PaulStat just wants to know if the second piece of code does the same thing in C# that the first code does in C++. I don't think he wants an optimization or anything.

Shouldn't this sort of thing be in a documentation somewhere, or a tutorial?
