New Post: CMYK to RGB for JPEG

I have looked at several threads here regarding CMYK to RGB conversion. I've also modeled my code after the samples. Neither of these routines places an icc profile in the jpeg file. I'm using version 6.8.8.901 x86.

    //Attempt 1
    using (MagickImage image = new MagickImage(args[0]))
    {
        image.AddProfile(ColorProfile.SRGB);
        image.ColorSpace = ColorSpace.sRGB;
        image.Write("cmyk1.jpg");
    }

    //Attempt 2
    using (MagickImage image = new MagickImage(args[0]))
    {
        image.AddProfile(new ColorProfile("sRGB_v4_ICC_preference.icc"));
        image.ColorSpace = ColorSpace.sRGB;
        image.Write("cmyk2.jpg");
    }

Please help me understand what I'm doing wrong.

Thanks,
Darren
