Storing Filename,Location and Size in an Array to Remember Selection Rectangle in Images

Question

I have 2 panels. The first panel shows a list of image files. When a user selects a file its displayed in a picturebox in the right panel. The user is allowed to select an area in the image. I need to save this selection for future use ie. to show the selection when this image is selected again. I intend to use an array with Multiple Data types

[Filename(string),Location(Point),Size(Size)]

Is this approach okay? Is there a better approach to solve this issue?

See this simple example: [How to call a method that uses coordinates variables](https://stackoverflow.com/a/53708936/7444103). More or less what the answers here are suggesting. You need a specialized class that can hold all the informations needed to store, serialize and restore the selections key values. The notes there may be interesting. — Jimi, Dec 17 '18 at 07:52
Also, you can use Jpeg metadata in order to save your parameter permanently. [Here is a good example](https://stackoverflow.com/a/23762564/4527628) — M.Armoun, Dec 17 '18 at 08:12

I'd say that the proper thing to do here is to first define a class to store the state associated to a single picturebox:

class PictureboxState
{
  public string Filename { get; set }
  public Point Location { get; set; }
  public Size Size { get; set; }
}

Then you keep an array of instances of this class; or even better, a dictionary where the keys are the pictureboxes (or something else that can identify the picturebox) and the values are the state objects.

The keys can be fullfilepath as it is unique for each selection. — techno, Dec 17 '18 at 07:47
