UpdateProperties Leave feedback
On this page
Updates known metadata properties satisfying the specified predicate. The operation is recursive so it affects all nested packages as well.
public virtual int UpdateProperties(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. |
The number of affected properties.
Please note that GroupDocs.Metadata implicitly checks the type of each filtered property. It’s impossible to update a property with a value having an inappropriate type.
