SendActivity.BeforeSend Event

Occurs before the SendActivity activity sends the message to the service.

Namespace:  System.Workflow.Activities
Assembly:  System.WorkflowServices (in System.WorkflowServices.dll)

public event EventHandler<SendActivityEventArgs> BeforeSend

This event handler associated with this event can be used to set the parameter values for the service operation being invoked.


The context of a SendActivity cannot be set in this event handler.

The following example shows how to use the BeforeSend event. This example was adapted from the Conversations SDK sample.

private void InitializeComponent()
    SendActivity sendActivity1 = new SendActivity();
    sendActivity1.BeforeSend += new EventHandler<SendActivityEventArgs>(sendActivity1_BeforeSend);

void sendActivity1_BeforeSend(object sender, SendActivityEventArgs e)
    Console.WriteLine("SendActivity1 BeforeSend event fired.");

void sendActivity1_AfterResponse(object sender, SendActivityEventArgs e)
    Console.WriteLine("SendActivity1 AfterResponse event fired.");
