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:
-
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.
-
Using
boxedvalue types — when boxing a value type, it is copied into an object on the heap. -
Using
newto 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.
