In dotNET we could write unmanaged code, where can I allocate memory dynamically (by keywords: stackalloc, new), use pointers etc.
It's possible to free memory (for example by something like delete in C++)?

5Please show an example. This is kind of vague at the moment. – Yuck Aug 01 '12 at 13:33

It depends how you allocate memory.
For example, if you allocate memory with AllocHGlobal :
double* vertices = (double*)Marshal.AllocHGlobal(
3 * count * Marshal.SizeOf(typeof(double)));
You allocate the array of doubles of a given size.
To free that memory after you have to call FreeHGlobal
Marshal.FreeHGlobal((IntPtr)vertices);
There are also other functions for allocating COM task memory, like
AllocCoTaskMem and relative FreeCoTaskMem

2Don't reuse your "answer" to write a completely different answer. Instead remove your old answer and write a new one if you change your mind. – Zano Aug 01 '12 at 13:45

Zano I'don't know that's prohibited to correct answer, i'am sorry – Aghilas Yakoub Aug 01 '12 at 13:46

Don't be sorry :-) It's not prohibited to correct an answer, but you changed the answer completely, which invalidates all the comments. In that case it's more practical to write a new question. – Zano Aug 01 '12 at 13:48
