A method that can participate in send activity events for the current turn.

public delegate System.Threading.Tasks.Task<Microsoft.Bot.Schema.ResourceResponse[]> SendActivitiesHandler(ITurnContext turnContext, List<Activity> activities, Func<Task<ResourceResponse[]>> next);

type SendActivitiesHandler = delegate of ITurnContext * List<Activity> * Func<Task<ResourceResponse[]>> -> Task<ResourceResponse[]>

Public Delegate Function SendActivitiesHandler(turnContext As ITurnContext, activities As List(Of Activity), next As Func(Of Task(Of ResourceResponse()))) As Task(Of ResourceResponse())

Parameters

turnContext: ITurnContext

The context object for the turn.

activities: List<Activity>

The activities to send.

next: Func<Task<ResourceResponse[]>>

The delegate to call to continue event processing.

Return Value

Task<ResourceResponse[]>

A task that represents the work queued to execute.

Remarks

A handler calls the next delegate to pass control to the next registered handler. If a handler doesn’t call the next delegate, the adapter does not call any of the subsequent handlers and does not send the activities.

If the activities are successfully sent, the next delegate returns an array of ResourceResponse objects containing the IDs that the receiving channel assigned to the activities. Use this array as the return value of this handler.
