MagickNet, Blob how can I use other profile

[Snapko]

In ImageMagickObject I can use other profile like this but how can I set other profile in MagickNet anybody now.
In MagickNet image object got a set_profile but I did not get it to work.

ImageMagickObject.MagickImageClass img = new MagickImageClass();
object[] obj = { "-geometry", 500, "-profile", "C:\\AdobeRGB1998.icc", "C:\\test.tif", "C:\\test.jpg" };
img.Convert(ref obj);
