How do I set properties of jpeg file in Xamarin for Android?

问题

I am working with jpeg files, when I look at the details of a jpeg file under windows (right-click->properties), under the Details tab there are entries for Title, Subject, Rating, Tags, Comments, etc. How can I set these properties in Xamarin (Android)? Thanks.

Here is some code to guide you.

ExifInterface newExif= new ExifInterface(filePath);
newExif.SetAttribute(ExifInterface.TagGpsLatitude, "teste lat");
newExif.SetAttribute(ExifInterface.TagGpsLatitudeRef, "teste lat ref");
newExif.SetAttribute(ExifInterface.TagGpsLongitude, "teste long");
newExif.SetAttribute(ExifInterface.TagGpsLongitudeRef, "teste long ref");
newExif.SaveAttributes();

You can use Android.Media.ExifInterface for getting/setting Exif Properties in Xamarin.Android.
