[RESOLVED] Looping through files that are in a ListView?

[blakemckenna]

I have a scenario where I have a Listview that contains Image files and their paths. I need to loop through the listview and retrieve each file and it's width and height and I'm not sure how to set this up in C# (I'm just beginning to learn C#).

Thanks,

Firstly, if you're well-versed in VB and learning C# then it might be beneficial to download and install Instant C# from Tangible Software Solutions. It will generally provide a 100% accurate conversion for even complex code using new features. You can then write code to do what you want in VB and generate an equivalent C# version.

As for this specific question, it depends exactly what you mean regarding the Images. The Images displayed in a ListView come from an ImageList and it determines the Size of those Images. If you want the Size of the original Image then you would need to retain a reference to the original Image rather than using the one in the ImageList. You could store that Image in the Tag property of the ListViewItem or you could create a new Image from the path as you loop, e.g.

foreach (ListViewItem item in listView1.Items)
{
    var filePath = item.Text;
    int imageWidth;
    int imageHeight;
 
    using (var image = Image.FromFile(filePath))
    {
        imageWidth = image.Width;
        imageHeight = image.Height;
    }
 
    // ...
}

That's exactly what I was looking for. Also, I never knew about that website for Code Converters. That's a great site.
