What will the following code display?

public struct Foo

  public int Value;
  public void Change(int newValue)
  {
    Value = newValue;
  }
}
public class Bar
{
  public Foo Foo { get; set; }
}
void Main()
{
  var bar = new Bar { Foo = new Foo() };
  bar.Foo.Change(5);
  Console.WriteLine(bar.Foo.Value);
}
