Getting known property descriptors Leave feedback

This code snippet demonstrates how to extract information about known properties that can be encountered in a particular package.

1. Load a file to examine
2. Get a collection of PropertyDescriptor instances for any desired metadata package
3. Iterate through the extracted descriptors

AdvancedUsage.GettingKnownPropertyDescriptors

using (Metadata metadata = new Metadata(Constants.InputDoc))
{
	var root = metadata.GetRootPackage<WordProcessingRootPackage>();
	foreach (var descriptor in root.DocumentProperties.KnowPropertyDescriptors)
	{
		Console.WriteLine(descriptor.Name);
		Console.WriteLine(descriptor.Type);
		Console.WriteLine(descriptor.AccessLevel);

		foreach (var tag in descriptor.Tags)
		{
			Console.WriteLine(tag);
		}

		Console.WriteLine();
	}
}

Note

Not all possible properties are presented in the KnowPropertyDescriptors collection. The library provides information on the most frequently used properties only. If there is no descriptor for some property it is still accessible through the GroupDocs.Metadata search engine in read-only mode.

You may easily run the code above and see the feature in action in our GitHub examples:

• GroupDocs.Metadata for .NET examples
• GroupDocs.Metadata for Java examples

Along with full featured .NET library we provide simple, but powerful free Apps. You are welcome to view and edit metadata of PDF, DOC, DOCX, PPT, PPTX, XLS, XLSX, emails, images and more with our free online Free Online Document Metadata Viewing and Editing App.
