A filter that creates another filter of type ImplementationType, retrieving missing constructor arguments from dependency injection if available there.

public ref class TypeFilterAttribute : Attribute, Microsoft::AspNetCore::Mvc::Filters::IFilterFactory, Microsoft::AspNetCore::Mvc::Filters::IOrderedFilter

[System.AttributeUsage(System.AttributeTargets.Class | System.AttributeTargets.Method, AllowMultiple=true, Inherited=true)]
public class TypeFilterAttribute : Attribute, Microsoft.AspNetCore.Mvc.Filters.IFilterFactory, Microsoft.AspNetCore.Mvc.Filters.IOrderedFilter

[<System.AttributeUsage(System.AttributeTargets.Class | System.AttributeTargets.Method, AllowMultiple=true, Inherited=true)>]
type TypeFilterAttribute = class
    inherit Attribute
    interface IFilterFactory
    interface IFilterMetadata
    interface IOrderedFilter

Public Class TypeFilterAttribute
Inherits Attribute
Implements IFilterFactory, IOrderedFilter

Inheritance: Attribute

Derived: Microsoft.AspNetCore.Mvc.TypeFilterAttribute<TFilter>

Attributes: AttributeUsageAttribute

Implements: IFilterFactory IFilterMetadata IOrderedFilter

Remarks

Primarily used in FilterCollection.Add calls.

Similar to the ServiceFilterAttribute in that both use constructor injection. Use ServiceFilterAttribute instead if the filter is itself a service.

Constructors

TypeFilterAttribute(Type)

Instantiates a new TypeFilterAttribute instance.

Properties

Arguments	Gets or sets the non-service arguments to pass to the ImplementationType constructor.
ImplementationType	Gets the Type of filter to create.
IsReusable	Gets a value that indicates if the result of CreateInstance(IServiceProvider) can be reused across requests.
Order	Gets the order value for determining the order of execution of filters. Filters execute in ascending numeric value of the Order property.

Methods

Creates an instance of the executable filter.
