āœ… Image source not being set with C#, WPF

I have a very basic C# statement but whenever it gets executed the image is not set and the image element disappears.
qrcode.Source = new BitmapImage(new Uri(@"/Images/scannn.png", UriKind.Relative));
qrcode.Source = new BitmapImage(new Uri(@"/Images/scannn.png", UriKind.Relative));
I have no clue why its not being set, the image is present in that directory, build action of the image is set to content and copy to output is set to copy always

I did not download your files, but I guess you create the image file from your app and then try to load it with the Uri path?

at first I create the image file and successfully save it and it gets saved i checked and then i set the saved image's location in the image source but that didnt work so then i tried something very straightforward which is setting the image source to an existing image in the Images folder but that didnt work either, so Ik i had the Bitmap so then i converted the Bitmap to BitmapImage and then set it but didnt work and finally rn I tried creating a new Image from code-behind itself and setting its source but didnt work either. In all of this i got the same result which is that the image is not visible

The key problem is, that if you want to use thoses relative "resources" they have to know at compile time You can add a dummy png file and set the properties to content and copy always/copy if newer

me too otherwise you have to use the full path and UriKind.Absolute

tried that too ig tried something very similar using System.IO.Path.Combine() and AppDomain.currentdomain base directory I also checked using File.Exists() and it was true . just found out that setting image source is working perfectly in a different XAML Page JUST MADE A PROGRESS there was a logic flaw in my code, when the function to set the image was called just after that there was a line of code that changed the image source but theres still some problem NVM I FIXED IT šŸ„¹
