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

[System.Diagnostics.DebuggerNonUserCode]
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.");
}
