在VB中实现发送邮件的功能,可以使用SMTP协议来发送邮件。可以按照以下步骤来实现:
Imports System.Net.Mail
Dim smtpServer As New SmtpClient("smtp.example.com")
smtpServer.Port = 25
smtpServer.Credentials = New Net.NetworkCredential("username", "password")
Dim mail As New MailMessage()
mail.From = New MailAddress("sender@example.com")
mail.[To].Add("receiver@example.com")
mail.Subject = "邮件主题"
mail.Body = "邮件正文"
mail.Attachments.Add(New Attachment("C:\path\to\file.txt"))
smtpServer.Send(mail)
完整的示例代码如下:
Imports System.Net.Mail
Public Sub SendEmail()
Dim smtpServer As New SmtpClient("smtp.example.com")
smtpServer.Port = 25
smtpServer.Credentials = New Net.NetworkCredential("username", "password")
Dim mail As New MailMessage()
mail.From = New MailAddress("sender@example.com")
mail.[To].Add("receiver@example.com")
mail.Subject = "邮件主题"
mail.Body = "邮件正文"
smtpServer.Send(mail)
End Sub
请注意替换示例代码中的SMTP服务器地址、端口、用户名、密码、发送方地址和接收方地址为实际的值。
