usage of 'using' in .NET

Question

In the example below, will the returned pen be destroyed(disposed) or not?

' VB'
Public Function GetPen() As System.Drawing.Pen
  Using pen As New System.Drawing.Pen(_Color, _Width)
    pen.DashStyle = _DashStyle
    Return pen
  End Using
End Function

// C#
public System.Drawing.Pen GetPen()
{
    using (System.Drawing.Pen pen = new System.Drawing.Pen(_Color, _Width)) 
    {
        pen.DashStyle = _DashStyle;
        return pen;
    }
}

[EDIT]

Just one more precision... Is the Pen object sent to the caller of GetPen by reference or 'cloned' like a structure? I know, this is a class, but with GDI objects I am never sure...

Will it be destroyed(disposed) the pen created in GetPen() when the external method will Dispose its pen obtained with GetPen()?

Answer 1

Yes, it will be disposed. You are then returning it in a disposed state, so it won't be any good for anything. If you want to use a factory method like this to return a Pen instance, you'll need to deal with disposing it yourself externally to the method, not using a using block within the method like this.
