Does the structure become a reference type when using the ref or out keywords in methods?

Structure (struct) in C# always remains a value type, even when passed to a method with the keywords ref or out. These keywords allow passing a reference to the structure variable, meaning the method can modify the structure itself, not just a copy, but the data type does not become a reference type.

Example:

struct Point { public int X, Y; }

void UpdatePoint(ref Point p) {
    p.X = 10;
    p.Y = 20;
}

Point pt = new Point();
UpdatePoint(ref pt); // pt will be changed

Here, Point remains a value type, but thanks to ref, the method accesses the original instance, not a copy.
