Return name of Bitmap file c#

Question

I am loading a picture from a file on my drive. After this, I click a button to add this file to a list and show it in a listbox. The code for adding the file to list looks like:

C#

listbox1.Items.Clear();
mainlibrary.AddPicture((Bitmap)Image.FromFile(picfilename)); //method adds loaded file to list
foreach (Bitmap item in mainlibrary.GetPictureList()) //gets all items in list
{
  listbox1.Items.Add(item.ToString());
}

The problem I'm having is that the code returns "System.Drawing.Bitmap" to listbox1, but I want to see the name of the bitmap file instead like "banana.jpg". How can I achieve this or what am I doing wrong?

Thank you.

Solution 1

A Bitmap object has no property that associates it with the file it may have been loaded from. You could create a new class that inherits Bitmap and add this extra property.

Solution 2

A bitmap doesn't "have" a file name - loading it from a file is not the only way to create one. In fact, Image.FromFile uses native windows calls to load the file - which creates a stream and reads it from that.

If you want to keep a file name with the bitmap data, you will have to create your own class (possibly derived from Image or Bitmap) which adds the extra information.

Is that the same with the Image class?

Yes - Image is the abstract base class from which Bitmap is derived, so it contains even less information!
