MetadataPackage.SetProperties method

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.

public int SetProperties(Func<MetadataProperty, bool> predicate, PropertyValue value)
Parameter Type Description
predicate Func`2 A function to test each metadata property for a condition.
value PropertyValue A new value for the filtered properties.

Return Value

The number of affected properties.


Please note that GroupDocs.Metadata implicitly checks the type of each filtered property. It’s impossible to set a property with a value having inappropriate type.
