Yea I thought of that, but doing so made it take twice the time:
list<rect*> rl;
for(int i=0; i<1000000; i++) {
rect *r=new rect;
r->x=i;
r->y=i;
r->width=i;
r->height=i;
rl.push_back(r);
}

Hi Cory,
In the C++ sample, you are passing the rect by value, so you are
saving a copy in the list. In C# a reference to the object is used, so
there is no copy-construction overhead.
You can change the list<rect> to a list<rect*>, but this way you have
to manage the memory by yourlself.

Just got done installing the VS.NET 2005 preview and did a small test.
I compared an ArrayList of Rectangles to a List<Rectangle>, and timed
inserting 1mil rects into each. I also wrote an equivalent c++ app.
Got some interesting results:
ArrayList: 265ms
List<Rectangle>: 62ms
list<rect>: 141ms
So it seems with generics .NET is finally faster than c++ (at least,
in this case).
