ActionFilterAttribute Class

Definition

Namespace:

Microsoft.AspNetCore.Mvc.Filters

Assembly:

Microsoft.AspNetCore.Mvc.Core.dll

Package:

Microsoft.AspNetCore.App.Ref v8.0.0

An abstract filter that asynchronously surrounds execution of the action and the action result. Subclasses should override OnActionExecuting(ActionExecutingContext), OnActionExecuted(ActionExecutedContext) or OnActionExecutionAsync(ActionExecutingContext, ActionExecutionDelegate) but not OnActionExecutionAsync(ActionExecutingContext, ActionExecutionDelegate) and either of the other two. Similarly subclasses should override OnResultExecuting(ResultExecutingContext), OnResultExecuted(ResultExecutedContext) or OnResultExecutionAsync(ResultExecutingContext, ResultExecutionDelegate) but not OnResultExecutionAsync(ResultExecutingContext, ResultExecutionDelegate) and either of the other two.

Methods

OnActionExecuted(ActionExecutedContext)	Called after the action executes, before the action result.
OnActionExecuting(ActionExecutingContext)	Called before the action executes, after model binding is complete.
OnActionExecutionAsync(ActionExecutingContext, ActionExecutionDelegate)	Called asynchronously before the action, after model binding is complete.
OnResultExecuted(ResultExecutedContext)	Called after the action result executes.
OnResultExecuting(ResultExecutingContext)	Called before the action result executes.
OnResultExecutionAsync(ResultExecutingContext, ResultExecutionDelegate)	Called asynchronously before the action result.
