Attributes: [RequiresUnreferencedCode("Uses reflection over runtime types which is not trim- or AOT-safe.")]

public IObservable<IObservedChange<object, object?>> GetNotificationForProperty(object sender, Expression expression, string propertyName)

View source

Inherited documentation

These docs were inherited from ICreatesObservableForProperty. The member doesn't override them on this type.

Summary: Subscribes to after-change notifications for the specified propertyName on sender.

Parameters

Name	Type	Description
`sender`	object	The object to observe.
`expression`	Expression	The expression describing the observed member.
`propertyName`	string	The property name to observe.

Returns: IObservable> -- An observable that produces an IObservedChange whenever the observed property changes.

2. Overload¶

Attributes: [RequiresUnreferencedCode("Uses reflection over runtime types which is not trim- or AOT-safe.")]

public IObservable<IObservedChange<object, object?>> GetNotificationForProperty(object sender, Expression expression, string propertyName, bool beforeChanged)

Summary: Subscribes to change notifications for the specified propertyName on sender.

Parameters

Name	Type	Description
`sender`	object	The object to observe.
`expression`	Expression	The expression describing the observed member.
`propertyName`	string	The property name to observe.
`beforeChanged`	bool	If true, signal before the property value changes; otherwise signal after the change.

Returns: IObservable> -- An observable that produces an IObservedChange whenever the observed property changes.

3. Overload¶

public IObservable<IObservedChange<object, object?>> GetNotificationForProperty(object sender, Expression expression, string propertyName, bool beforeChanged, bool suppressWarnings)

Summary: Subscribes to change notifications for the specified propertyName on sender.

Parameters

Name	Type	Description
`sender`	object	The object to observe.
`expression`	Expression	The expression describing the observed member. This is typically a MemberExpression or an IndexExpression.
`propertyName`	string	The property name to observe.
`beforeChanged`	bool	If true, signal before the property value changes; otherwise signal after the change.
`suppressWarnings`	bool	If true, warnings should not be logged.

Returns: IObservable> -- An observable that produces an IObservedChange whenever the observed property changes. If observing is not possible for the specified beforeChanged value, implementations should return an observable that never produces values.

Remarks

        The expression describes the observed member and is used to populate
        IObservedChange instances emitted by the returned observable.

Exceptions

Type	Condition
System.ArgumentException	Thrown when sender is not compatible with the observing mechanism implemented by the instance.
