If you already have GroupDocs.Metadata for .Net and want to upgrade it, please execute Update-Package GroupDocs.Metadata to get the latest version.

Please check the GitHub Repository for other common usage scenarios.

Use C# to Remove All Metadata Properties from a File

using (Metadata metadata = new Metadata(Constants.InputPdf))
{
    // Remove detected metadata packages
    var affected = metadata.Sanitize();
    Console.WriteLine("Properties removed: {0}", affected);

    metadata.Save(Constants.OutputPdf);
}

Extract Metadata from Files via C# Code

foreach (string file in Directory.GetFiles(Constants.InputPath))
{
    using (Metadata metadata = new Metadata(file))
    {
        if (metadata.FileFormat != FileFormat.Unknown && !metadata.GetDocumentInfo().IsEncrypted)
        {
            Console.WriteLine();
            Console.WriteLine(file);

            // fetch all metadata properties that fall into a particular category
            var properties = metadata.FindProperties(p => p.Tags.Any(t => t.Category == Tags.Content));
            Console.WriteLine("The metadata properties describing some characteristics of the file content: title, keywords, language, etc.");
            foreach (var property in properties)
            {
                Console.WriteLine("{0} = {1}", property.Name, property.Value);
            }

            // fetch all properties having a specific type and value
            var year = DateTime.Today.Year;
            properties = metadata.FindProperties(p => p.Value.Type == MetadataPropertyType.DateTime &&
                                                     p.Value.ToStruct(DateTime.MinValue).Year == year);

            Console.WriteLine("All datetime properties with the year value equal to the current year");
            foreach (var property in properties)
            {
                Console.WriteLine("{0} = {1}", property.Name, property.Value);
            }
