Examples

This example demonstrates how to search for specific metadata properties using tags.

using (Metadata metadata = new Metadata(Constants.InputPptx))
{
    // Fetch all the properties satisfying the predicate:
    // property contains the name of the last document editor OR the date/time the document was last modified
    var properties = metadata.FindProperties(p => p.Tags.Contains(Tags.Person.Editor) || p.Tags.Contains(Tags.Time.Modified));
    foreach (var property in properties)
    {
        Console.WriteLine("Property name: {0}, Property value: {1}", property.Name, property.Value);
    }
}
