Contoh

Contoh kode berikut menunjukkan implementasi Execute metode . Dalam contoh ini, pesan email Outlook dibuat dan dikirim. Contoh ini berasal dari sampel SDK Panduan Alur Kerja Outlook. Untuk informasi selengkapnya, lihat Sampel Panduan Alur Kerja Outlook.

protected override ActivityExecutionStatus Execute(ActivityExecutionContext context)
{
    // Create an Outlook Application object.
    Outlook.Application outlookApp = new Outlook.Application();

    Outlook._MailItem oMailItem = (Outlook._MailItem)outlookApp.CreateItem(Outlook.OlItemType.olMailItem);
    oMailItem.To = outlookApp.Session.CurrentUser.Address;
    oMailItem.Subject = "Auto-Reply";
    oMailItem.Body = "Out of Office";

    //adds it to the outbox
    if (this.Parent.Parent is ParallelActivity)
