Methods

BeginExecute(ControllerContext, IDictionary<string, object>, AsyncCallback, object)

Begins running the asynchronous action method by using the specified parameters and controller context.

public override IAsyncResult BeginExecute(ControllerContext controllerContext, IDictionary<string, object> parameters, AsyncCallback callback, object state)

Parameters

controllerContext ControllerContext

The controller context.

parameters IDictionary<string, object>

The parameters of the action method.

callback AsyncCallback

state object

An object that contains information to be used by the callback method. This parameter can be null.

Returns

IAsyncResult

An object that contains the result of an asynchronous call.

EndExecute(IAsyncResult)

Returns the result of an asynchronous operation.

public override object EndExecute(IAsyncResult asyncResult)

Parameters

asyncResult IAsyncResult

An object that represents the status of an asynchronous operation.

Returns

object

The result of an asynchronous operation.

GetCustomAttributes(bool)

Returns an array of custom attributes that are defined for this member, excluding named attributes.

public override object[] GetCustomAttributes(bool inherit)

Parameters

inherit bool

true to look up the hierarchy chain for the inherited custom attribute; otherwise, false.

Returns

object[]

An array of custom attributes, or an empty array if no custom attributes exist.

GetCustomAttributes(Type, bool)

Returns an array of custom attributes that are defined for this member, identified by type.

public override object[] GetCustomAttributes(Type attributeType, bool inherit)

Parameters

attributeType Type

The type of the custom attributes to return.

inherit bool

true to look up the hierarchy chain for the inherited custom attribute; otherwise, false.

Returns

object[]

An array of custom attributes, or an empty array if no custom attributes of the specified type exist.

GetFilterAttributes(bool)

Gets the filter attributes.

public override IEnumerable<FilterAttribute> GetFilterAttributes(bool useCache)

Parameters

useCache bool

Use cache flag.

Returns

IEnumerable<FilterAttribute>

GetSelectors()

Returns the action-method selectors.

public override ICollection<ActionSelector> GetSelectors()

Returns

ICollection<ActionSelector>

The action-method selectors.

IsDefined(Type, bool)

Determines whether one or more instances of the specified attribute type are defined for the action member.

public override bool IsDefined(Type attributeType, bool inherit)

Parameters

attributeType Type

The type of the custom attribute.

inherit bool

true to look up the hierarchy chain for the inherited custom attribute; otherwise, false.

Returns
