RE: ValueType reference in objects

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

If your goal is to simply find a way to pass in integer pointers, then the
following code will work. I would like to point out that using pointers and
unsafe code is NOT recommended and should be reserved for special case
scenarioes.

You will also need to check the "Allow unsafe code" option in the Build tab
of your project properties.

unsafe class MyClass
{
public int* i;
public MyClass(int* I)
{
i = I;
}
}

class Program
{
unsafe static void Main(string[] args)
{
int i = 50;
MyClass c = new MyClass(&i);
Console.WriteLine(*c.i);

i = 10;
Console.WriteLine(*c.i);

Console.ReadLine();
}
}

HTH :-)

Hi all,

With the followin code:

class MyClass
{
public int i;
public MyClass(ref int I)
{
i = I;
}
}

class Program
{
static void Main(string[] args)
{
int i = 50;
MyClass c = new MyClass(ref i);
Console.WriteLine(c.i);

i = 10;
Console.WriteLine(c.i);

Console.ReadLine();
}
}

I´ve got:

50
50

The i field from c object didn´t change its value.
The i field doesn´t point to i address.

C# copies the value from the i variable to the object heap field i.
Is this correct? Heap object doesn´t point to stack variables?

Please help.

TIA,
