Can you explain how dynamic memory management works when using the heap?

Dynamic memory management in the heap means that memory is allocated and freed during program execution, not beforehand. In C#, objects created with the new operator are placed in the heap. The runtime environment (CLR) automatically manages this memory using a garbage collector.

When an object is created, memory for it is allocated in the heap. If the object is no longer used (no references to it), the garbage collector frees this memory so it can be reused. This helps prevent memory leaks and manual memory management.

Example:

class Program
{
    static void Main()
    {
        var obj = new MyClass(); // memory is allocated in the heap
        // work with obj
    } // after exiting the scope, the garbage collector may free the memory
}

class MyClass
{
    public int Value;
}
