本文介绍了多种邮件发送方案，包括使用Outlook组件、ASP.NET中引用System.Web.Mail类、在VB.NET或C#中使用System.Net.Sockets、IIS SMTP自带的CDONTS组件以及JMail组件，给出了各方案的优缺点和代码示例，选择方案需视程序用途和需求而定。

        Dim outObj As New Outlook.Application()
        Dim Item As Outlook.MailItemClass

        Item.Subject = "hello"
        Item.Body = "hell"
        Item.Attachments.Add("C:/abc.txt")
        Item.Send()
End Sub
