Asp.net 自动发送邮件的方法
今天有一个模块需要自动发送邮件的功能，就随便写了一个，记录一下作为积累。
一、首先需要配置web.config文件：
<system.net>
<mailSettings>
<smtp from="Emailname">
<network host="smtp.163.com" userName="Emailname" password="Emailpassword"
port="25" defaultCredentials="false"/>
</smtp>
</mailSettings>
</system.net>
二、然后编写发送邮件的函数：
'''/ <summary>
''' 邮件发送方法(带附件)
''' </summary>
''' <param name="mailto">收件人地址。如：receiver@163.com</param>
''' <param name="mailsubject">邮件标题</param>
''' <param name="mailbody">邮件正文</param>
''' <param name="mailFrom">邮件发送人地址。如：sender@163.com</param>
''' <param name="list">附件路径</param>
''' <returns></returns>
Public Function MySendMail(ByVal mailto As String, ByVal mailsubject As String, ByVal mailbody As String, ByVal mailFrom As String, ByVal list As ArrayList) As Boolean
Try
'邮件发送人地址
Dim from As New System.Net.Mail.MailAddress(mailFrom)
'如test@163.com,初步测试，用test@sina.com不行，用163的邮件服务器，就必须用163邮箱的用户名
'收件人地址
Dim [to] As New System.Net.Mail.MailAddress(mailto)
'如test@tom.com
Dim mail As New System.Net.Mail.MailMessage(from, [to])
mail.Subject = mailsubject
mail.Body = mailbody
'以下设置服务器
Dim mySmth As New System.Net.Mail.SmtpClient()
'以下为增加附件
Dim count As Integer = list.Count
For i As Integer = 0 To count - 1
Dim data As New System.Net.Mail.Attachment(list(i).ToString())
mail.Attachments.Add(data)
Next
mySmth.Send(mail)
mail.Dispose()
Return True
Catch
Return False
End Try
End Function
三、最后就是对函数的调用了：
Dim mailSubject As String = "会员注册确认函"
Dim mailBody As String = "正文内容。"
Dim mailFrom As String = ConfigurationManager.AppSettings("SendMail")
Dim List As New ArrayList()
List.Add(Server.MapPath(ConfigurationManager.AppSettings("SendMailText")))
'发送成功，进行相应处理
If MySendMail(Me.txtEmail.Text, mailSubject, mailBody, mailFrom, List) Then
Else
'发送失败，进行相应处理
Return
End If
