c# GetFile, GetFilePreview

I use C# Appwrite 0.7 package, and I’m on Appwrite 1.14, I try to get a file from a bucket using

var storage = new Storage(client);
File result = await storage.GetFile(
bucketId: "[BUCKET_ID]",
fileId: "[FILE_ID]");

it return the file in result, but I haven’t found the method to show it in picture box, I found some old doc using file.Content, but it doesn’t work anymore.
After this I tried to get a preview using

var storage = new Storage(client);
byte[] result = await storage.GetFilePreview(
bucketId: "[BUCKET_ID]",
fileId: "[FILE_ID]");

but this time, I get result=null, and it’s the same thing for: GetFileView, or GetFileDownload.
Please help, I’m struggling, I would like to use GetFile and GetFilePreview, all the files are jpg images, and under 5mo.
Thanks a lot

In general, how do you handle images in your tech stack?

before appwrite, i was using sql server, putting images directly in the db,
now, i tried to use
var storage = new Storage(client);
File result = await storage.GetFile(
bucketId: "[BUCKET_ID]",
fileId: "[FILE_ID]");
byte[] file = Encoding.UTF8.GetBytes(result.Content); //here the problem, no content
if (result != null)
using (MemoryStream stream = new MemoryStream(file))
{
Image image = Image.FromStream(stream);
picDocument.Image = image;
}

and with this :
var storage = new Storage(client);
byte[] result = await storage.GetFilePreview(
bucketId: "[BUCKET_ID]",
fileId: "[FILE_ID]");
if (result != null) //result is always null
{
Image image = Image.FromStream(stream);
picDocument.Image = image;
}

thanks for your help
