I'm looking a way to save information like a relationship between neighborhood pixel values in an image. Is there anyway to save a list of elements/linked list inside an image? Please suggest some ways to save it inside my image as a secret information which is hard to remove .

It looks like you're talking about steganography[^].

There are quite a lot of examples found if you search Google with that term. To mention a few:
- Steganography - Hiding data in plain sight[^]
- Steganography - Hiding messages in the Noise of a Picture[^]
- Steganography: Simple Implementation in C#[^].

Note that the removal of the information cannot be controlled since if the picture is modified, your data may be lost.

thnakyou.. In my case, have to generate secrete code/signature of embedding. (my project based on watermarking) That code should be with embedded locations in the cover image . For that, need to save information in an image.

My out put should be like this ;
List<dictionary<int, int[]="">> globalList = new List<dictionary<int, int[]="">>();
// list contains a map for [water mark pixel, {matching cover image pixel, best match value}] for each watermark
