dynamic memory allocation

[Jakop Nielsen]

I wanted to play arround with unsafe code in c# but failed to make a simple
allocation.

How do I do something like this c code in c#?

int *p=new int[100];

Jakop,

Simple, declare an integer array, like this:

// Declare an integer array.
int[] p = new int[100];

This will create an integer array with 100 elements in it.

Hopet his helps.

Hi Jakop,
In the MSDN it has a sample tutorial about unsafe code see
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/csref/html/
vcwlkunsafecodetutorial.asp and
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/csref/html/
vclrfUnsafe.asp (be careful of word wrap). Basically, you must use the
unsafe keyword and compile with the /unsafe command-line parameter. You may
also need to use the fixed statement to keep the garbage collector from
moving the memory on you.

try:
unsafe {
int* p = stackalloc int[100];
}

see section 25.7 Stack allocation and 25.8 Dynamic memory allocation
of the C# Spec.
