Where in memory is a data structure (struct) usually stored?

In C#, structures (struct) are value types. They are usually stored on the stack if declared as local variables within a method. If the structure is a field of a class or resides within another object, it is stored on the heap along with that object.

Example:

struct Point { public int X, Y; }

void Method() {
    Point p = new Point(); // p is stored on the stack
}

class Container {
    public Point p; // p is stored on the heap along with the Container object
}
