Questionstack / heap assignment under the hood Pin
taking_liberties29-Jul-14 4:06
taking_liberties29-Jul-14 4:06 
Could someone elaborate on how the runtime determines where to allocate a variable (stack/heap)?

class MyClass()
{
int x;
}

private void AssignmentCheck()
{
MyClass mc = new MyClass();
mc.x = 10;
int MyInt = 5;
}


space will be allocated on the heap for the new instance of MyClass and the reference to the heap location will be saved to the variable mc.
mc.x is on the heap and MyInt will be on the stack.

My question is how does the runtime know to allocate space on the heap for MyClass and space on the stack for myInt ?

Does the runtime do some kind of type checking prior to assignment ?
i.e.
ok, MyClass is a ref type, I'd better put it on the heap
MyInt derives from System.ValueType and it's a local variable, I'd better put it on the stack.

Obviously an implementation detail but curious to know..

thx in advance
