asp.net怎么把表单数据发送到指定的邮箱

用gmail发送的，根据你自己的邮箱调整一下就可以了
Sub sendmail(ByVal args() As String)        If args.Length < 4 Then
            'Console.WriteLine( _
            '    "Expected: mailer.exe [from] [to] [subject] [message]")
            Response.Write("Expected: mailer.exe [from] [to] [subject] [message]")
            Exit Sub
        End If        ' Set mailServerName to be the name of the mail server
        ' you wish to use to deliver this message
        Dim mailServerName As String = "smtp.gmail.com"
        Dim fromAddress As String = args(MailMessagePart.ToAddress)
        Dim toAddress As String = args(MailMessagePart.FromAddress)
        Dim subject As String = args(MailMessagePart.Subject)
        Dim body As String = args(MailMessagePart.Message)
        Try
            ' MailMessage is used to represent the e-mail being sent
            Using message As _
                New MailMessage(fromAddress, toAddress, subject, body)                ' SmtpClient is used to send the e-mail
                Dim mailClient As New SmtpClient(mailServerName)
                ' UseDefaultCredentials tells the mail client to use the
                ' Windows credentials of the account (i.e. user account)
                ' being used to run the application
                message.IsBodyHtml = True
                message.BodyEncoding = System.Text.Encoding.UTF8
                mailClient.Port = 587
                mailClient.EnableSsl = True                mailClient.Credentials = New System.Net.NetworkCredential("gmail帐号", "gmail密码")
                'mailClient.UseDefaultCredentials = True
                ' Send delivers the message to the mail server
                'message.To.Add(New MailAddress("receive E-mail Address"))                mailClient.Send(message)
            End Using
            Response.Write("Message sent.")
        Catch ex As FormatException
            Response.Write(ex.Message)
        Catch ex As SmtpException
            Response.Write(ex.Message)

    End Sub

  Mail.SendMail(txtEmail.Text, subject, body);

我用的jmail组件
    protected bool sendemail()
    {
        jmail.Message jmail = new jmail.Message();
        jmail.Silent = true;
        jmail.Logging = true;
        jmail.Charset = "UTF-8";
        jmail.Encoding = "Base64";
        jmail.AddRecipient("[email protected]","","");
        jmail.AddRecipientCC("[email protected]","","");
        jmail.From = "[email protected]";
        jmail.MailServerUserName = "方";
        jmail.MailServerPassWord = ".......";
        jmail.Subject = "测试主题";
        jmail.HTMLBody = "内容";
        bool flag = jmail.Send("smtp.163.com.cn", false);
        return flag;
    }这样写有错么，jmail.Send（）里面的参数是什么意思啊  怎么写的？？电脑上要不要装什么发邮件的东西？？谁给我详细说一下啊
