CachedImage - Access the downloaded file

Question

I am using the CachedImage component of ffimageloading. I have a kind of gallery with a carousel view.

All the images are loaded through an internet URL, they are not local images. I would like to add the image sharing function. But I don't want to download the file again, I would like to know if there is a way to access the file that the CachedImage component already downloaded to be able to reuse it in the share function.

Hello,​

Welcome to our Microsoft Q&A platform!

Hi, Barto. To get the cached image, try using the MD5Helper.

   var filepath = ImageService.Instance.MD5Helper.MD5("the file url");  

Refer to: https://github.com/luberda-molinet/FFImageLoading/issues/1214#issuecomment-472073935

Thanks @JarvanZhang

I share with you how part of my code is:

   var key = ImageService.Instance.Config.MD5Helper.MD5("https://yourfileUrlOrKey");  
   var imagePath = await ImageService.Instance.Config.DiskCache.GetFilePathAsync(key);  
   var tempFile = Path.Combine(Path.GetTempPath(), "test.jpg");  
   if (File.Exists(tempFile))  
   {  
       File.Delete(tempFile);  
   }  
   File.Copy(imagePath, tempFile);  
  
   await Share.RequestAsync(new ShareFileRequest  
   {  
       Title = "Test",  
       File = new ShareFile(tempFile)  
   });  

The temporary file I believe, since the cached file has no extension and the applications do not recognize the type.
