How to convert a Rect ToString, while limiting decimal places?

Question

Is there a simple format provider that will return a Rect structure ToString and limit the number of decimal places?

System.Windows.Rect myRect;

If I use myRect.ToString(), it returns

myRect: 0.0139211136847734,0.109375,0.995359599590302,1

I want this, limiting numbers to two decimal places but myRect.ToString("D2") does not compile

 myRect: 0.01,0.10,0.99,1

Note: I don't care about rounding, rounded or truncated is fine.

You could create an extension method:

public static class RectExtensions
{
    public static string ToStringRounded(this System.Windows.Rect rect)
    {
        return string.Format("{0},{1},{2},{3}", 
            Math.Round(rect.X, 2), Math.Round(rect.Y, 2), 
            Math.Round(rect.Width, 2), Math.Round(rect.Height, 2));
    }
}

and then call myRect.ToStringRounded();

Don't forget to include the namespace of the extension method
