In C#, value types (struct) are usually placed on the stack, but they can also be placed on the managed heap in the following ways:

  1. Embedding in a reference type — if the value type is a field of a class (reference type), it is stored inside the object on the heap.

  2. Using boxed value types — when boxing a value type, it is copied into an object on the heap.

  3. Using new to create an instance of struct inside a class or array — arrays of value types and struct fields inside classes are placed on the heap.

Example:

struct Point { public int X, Y; }

class Container {
    public Point p; // Point is stored on the heap as part of the Container object
}

Container c = new Container(); // object c and field p on the heap

object o = c.p; // boxing: copy of p on the heap as an object

Thus, value types can be on the heap if they are part of a reference type or are boxed.
