Methods

Name Description
virtual AddProperties(Func<MetadataProperty, bool>, PropertyValue) Adds known metadata properties satisfying the specified predicate. The operation is recursive so it affects all nested packages as well.
Clear() Removes all writable metadata properties from the package.
ClearBuiltInProperties() Removes all built-in metadata properties.
ClearCustomProperties() Removes all custom metadata properties.
Contains(string) Determines whether the package contains a metadata property with the specified name.
virtual FindProperties(Func<MetadataProperty, bool>) Finds the metadata properties satisfying the specified predicate. The search is recursive so it affects all nested packages as well.
GetEnumerator() Returns an enumerator that iterates through the collection.
Remove(string) Removes a writable metadata property by the specified name.
virtual RemoveProperties(Func<MetadataProperty, bool>) Removes metadata properties satisfying the specified predicate.
virtual Sanitize() Removes writable metadata properties from the package. The operation is recursive so it affects all nested packages as well.
Set(string, bool) Adds or replaces the metadata property with the specified name.
Set(string, DateTime) Adds or replaces the metadata property with the specified name.
Set(string, double) Adds or replaces the metadata property with the specified name.
Set(string, int) Adds or replaces the metadata property with the specified name.
Set(string, string) Adds or replaces the metadata property with the specified name.
virtual SetProperties(Func<MetadataProperty, bool>, PropertyValue) Sets known metadata properties satisfying the specified predicate. The operation is recursive so it affects all nested packages as well. This method is a combination of AddProperties and UpdateProperties. If an existing property satisfies the predicate its value is updated. If there is a known property missing in the package that satisfies the predicate it is added to the package.
virtual UpdateProperties(Func<MetadataProperty, bool>, PropertyValue) Updates known metadata properties satisfying the specified predicate. The operation is recursive so it affects all nested packages as well.

Examples

This example demonstrates how to update built-in metadata properties in a presentation.

using (Metadata metadata = new Metadata(Constants.InputPptx))
{
    var root = metadata.GetRootPackage<PresentationRootPackage>();

    root.DocumentProperties.Author = "test author";
    root.DocumentProperties.CreatedTime = DateTime.Now;
    root.DocumentProperties.Company = "GroupDocs";
    root.DocumentProperties.Category = "test category";
    root.DocumentProperties.Keywords = "metadata, built-in, update";

    // ... 

    metadata.Save(Constants.OutputPptx);
}
