AsyncController.IAsyncController.BeginExecute Method
Called by ASP.NET to begin the execution of an asynchronous action method.
Namespace: System.Web.Mvc
Assembly: System.Web.Mvc (in System.Web.Mvc.dll)
Syntax
'Declaration
Private Function BeginExecute ( _
requestContext As RequestContext, _
callback As AsyncCallback, _
state As Object _
) As IAsyncResult Implements IAsyncController.BeginExecute
'Usage
Dim instance As AsyncController
Dim requestContext As RequestContext
Dim callback As AsyncCallback
Dim state As Object
Dim returnValue As IAsyncResult
returnValue = CType(instance, IAsyncController).BeginExecute(requestContext, _
callback, state)
IAsyncResult IAsyncController.BeginExecute(
RequestContext requestContext,
AsyncCallback callback,
Object state
)
private:
virtual IAsyncResult^ BeginExecute(
RequestContext^ requestContext,
AsyncCallback^ callback,
Object^ state
) sealed = IAsyncController::BeginExecute
JScript does not support explicit interface implementations.
Parameters
- requestContext
Type: System.Web.Routing.RequestContext
The request context.
- callback
Type: System.AsyncCallback
The asynchronous callback method.
- state
Type: System.Object
An object that contains information to be used by the callback method. This parameter can be null reference (Nothing in Visual Basic).
Return Value
Type: System.IAsyncResult
The status of the asynchronous operation.
Implements
IAsyncController.BeginExecute(RequestContext, AsyncCallback, Object)
Remarks
This method is called by ASP.NET while it is processing an asynchronous action method. It cannot be called directly.
This member is an explicit interface member implementation. It can be used only when the AsyncController instance is cast to an IAsyncResult interface.
