public abstract object GetValue (object component);
public abstract object? GetValue (object? component);
abstract member GetValue : obj -> obj
Public MustOverride Function GetValue (component As Object) As Object
Parameters
- component
- Object
The component with the property for which to retrieve the value.
Returns
The value of a property for a given component.
Remarks
Typically, this method is implemented through reflection.
This method automatically calls the pre-change method, OnComponentChanging, and post-change method, OnComponentChanged, of the IComponentChangeService.
Notes to Implementers
When you override this method, it gets the current value of the property by invoking a "GetMyProperty" method that you need to implement. An exception in that method should pass through.
