LocationInterceptionAspect.OnSetValue Method

Method invoked instead of the Set semantic of the field or property to which the current aspect is applied, i.e. when the value of this field or property is changed.

Namespace:  PostSharp.Aspects
Assembly:  PostSharp (in PostSharp.dll) Version: 2023.0.3.0 (2023.0.3.0)
public virtual void OnSetValue(
	LocationInterceptionArgs args


Type: PostSharp.Aspects.LocationInterceptionArgs
Advice arguments.



This method is invoked instead of the setter of the property to which the current aspect is applied. If it is applied to a field, that field is transformed into a property. This method intercepts all writes to static properties, but it does not intercept inline initializers of instance properties; use OnInstanceLocationInitialized(LocationInitializationArgs) for that.

If you apply this advice to a getter-only auto-implemented property, PostSharp will create a setter that will be called in these cases:

  • for static properties, instead of the property inline initialization or property assignment from the static constructor;
  • for instance properties, only instead of the property assignment from the constructor but not for the inline initialization (use the OnInstanceLocationInitialized(LocationInitializationArgs) advice to intercept inline initialization of an instance property).
