thumbnail in imagemagick

[laleh]

I want to make thumbnail a image but I have the following error

NullReferenceException: Object reference not set to an instance of an object.

I use this code :

Code: Select all

    using (MagickImage image = new MagickImage(mainpath + media.Name))
                {
                    ExifProfile profile = image.GetExifProfile();

                    using (MagickImage thumbnail = profile.CreateThumbnail())
                    {
                       // if (thumbnail != null)
                            thumbnail.Write(paththumb + media.Name);
                    }
                }

image.GetExifProfile() can return null so you also need check for that: profile?.CreateThumbnail(). And you probably want to do image.Thumbnail() instead.

Yes , I want to do thumbnail for image . but image.thumbnail() is not defined.

It is "Thumbnail" not "thumbnail".
