Ejemplos

En el ejemplo de código siguiente se muestra cómo llamar a este método.

static void CreateMessageWithAttachment( String^ server )

   // This example assumes that a file named Data.xls exists in the
   // current working directory.

   // Create a message and set up the recipients.

   // Create  the file attachment for this email message.
