Memory Management in C# for a class members

Prashant Choubey

Could you please explain where the memory would be allocated for each of the members listed below if I create an Instance of the following class 'clsTest'. If you could let me know any way using Visual studio to identify the memory allocation would be great.

intVal

strVal

strValueStatic

doSomething

funIntVal

funStrVal

class clsTest

{

int intVal;
string strVal;
static string strValueStatic;
public void doSomething(int x, string y)
{
      int funIntVal = x;
      string funStrVal = y ;
      Console.WriteLine("output : {0}, {1)", funIntVal.ToString() , funStrVal);
}

}

Thanks in advance!

Here class variable is get allocated on the heap as there are part of referance type class.

Where as local variable of function get allocated on stack as they are local variable in function.
Check this :
If a value type is part of a class (as in your example), it will end up on the heap.
If it's boxed, it will end up on the heap.
If it's in an array, it will end up on the heap.
If it's a static variable, it will end up on the heap.
If it's captured by a closure, it will end up on the heap.
If it's used in an iterator or async block, it will end up on the heap.
If it's created by unsafe or unmanaged code, it could be allocated in any type of data structure (not necessarily a stack or a heap).

@pranay, Thanks for you response.

As I know about static members shares a one copy across all instance, so if static member also get created in heap memory, and heap memory can be accessed by instance (ref) but its not a case with static bcz static accessed by type not instance...
