What is the best EXIF library for .Net?

Question

I am looking for simple straightforward solution for accessing EXIF information of jpeg images in .Net. Does anybody has experience with this?

Answer 1

If you're willing to use an open-source library, may I humbly suggest one of my own creation?

The metadata-extractor project has been alive and well since 2002 for Java, and is now available for .NET.

• Open source (Apache 2.0)
• Heavily tested and widely used
• Supports many image types (JPEG, TIFF, PNG, WebP, GIF, BMP, ICO, PCX...)
• Supports many metadata types (Exif, IPTC, XMP, JFIF, ...)
• Supports many manufacturer-specific fields (Canon, Nikon, ...)
• Very fast (fully processes ~400 images totalling 1.33GB in ~3 seconds) with low memory consumption
• Builds for .NET 3.5, .NET 4.0+ and PCL

It's available via NuGet or GitHub.

Sample usage:

IEnumerable<Directory> directories = ImageMetadataReader.ReadMetadata(path);  foreach (var directory in directories) foreach (var tag in directory.Tags)     Console.WriteLine($"{directory.Name} - {tag.TagName} = {tag.Description}"); 

Answer 2

If you're compiling against v3 of the Framework (or later), then you can load the images using the BitmapSource class, which exposes the EXIF metadata through the Metadata property
