And you also need to call "GC.minimize()" after a

Hi again Steve, or anyone else whose reading this.
I was playing around with D and C# and need help getting this
array stuff to work.
My D program:
import std.stdio, std.cstream, std.array;
void main()
{
string[] temp_array = new string[1];
for(int i=0;i<1;i++)

Can you please give me a correct example of:
- creating a dynamic string array
auto arr = new char[N];
N can be a runtime value.
- looping over it and adding values
Not sure what you mean here.

The memory usage shrinks from 400MB to 2MB, which is right!
Why?

Thanks you guys for all the suggestions.

I have played around with GC.free, see below for more details.

I found this problem with a program that reads a large xml file
(25+ lines), then stores the lines in a string[], does a
comparison with another array and finally clears the original
array.
On the second or third file I always get an OutOfMemoryError,
when the Task Manager shows about 1.3GB
Why isn't the memory deallocating?
The memory might be free, but still not released to the OS.
Especially in windows, when you free memory it still isn't freed
from
your process.
But you can reuse it in your program if the GC has collected it.
The correct test would be to copy and paste the

The system is Windows Vista 64bit. DMD is 2.062.
DMD doesn't yet produce 64 bit binaries on Windows.
I have tried to solve your problem using GC.free, but I am not
seeing good results...

GC.minimize() may work.
