使用asp.net从gmail收件箱中获取邮件

Question

我正在为公司开发网站，他们需要从邮件收件箱中提取 from_address，subject，some contents （mob_no，place等）等邮件内容并显示在网站上（网格视图）。我试图用Pop3连接到 gmail ，代码如下

我使用的代码是：

Imports OpenPop.Pop3
Imports OpenPop.Mime
    Protected Sub Read_Emails(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim pop3Client As Pop3Client
        If (Session("Pop3Client") Is Nothing) Then
            pop3Client = New Pop3Client
            pop3Client.Connect("pop.gmail.com", 110, False)
            pop3Client.Authenticate("mymail@gmail.com", "trustme")
            Session("Pop3Client") = pop3Client
        Else
            pop3Client = CType(Session("Pop3Client"), Pop3Client)
            MsgBox(pop3Client)
        End If
        Dim count As Integer = pop3Client.GetMessageCount
        Dim dtMessages As DataTable = New DataTable
        dtMessages.Columns.Add("MessageNumber")
        dtMessages.Columns.Add("From")
        dtMessages.Columns.Add("Subject")
        dtMessages.Columns.Add("DateSent")
        Dim counter As Integer = 0
        Dim i As Integer = count
        Do While (i >= 1)
            Dim message As Message = pop3Client.GetMessage(i)
            dtMessages.Rows.Add()
            dtMessages.Rows((dtMessages.Rows.Count - 1))("MessageNumber") = i
            dtMessages.Rows((dtMessages.Rows.Count - 1))("From") = message.Headers.From.Address
            dtMessages.Rows((dtMessages.Rows.Count - 1))("Subject") = message.Headers.Subject
            dtMessages.Rows((dtMessages.Rows.Count - 1))("DateSent") = message.Headers.DateSent
            counter = counter + 1
            i = i - 1
            If counter = 5 Then
                Exit Do
            End If
        Loop
        gvEmails.DataSource = dtMessages
        gvEmails.DataBind()
    End Sub

但问题是：它会导致错误“找不到服务器”

通过引用https://stackoverflow.com/users/1750602/khaksar-weqar 回答我与gmail收件箱建立了联系，使用上述代码提取了一些内容。现在我想将正文内容作为文本提取到我的asp文本框，这是他们的任何可能吗？积极的回应表示赞赏。

只需更改代码的下方部分：

pop3Client.Connect("pop.gmail.com", 110, False)
pop3Client.Authenticate("mymail@gmail.com", "trustme")

进入：

pop3Client.Connect("pop.gmail.com", 995, True)
pop3Client.Authenticate("mymail@gmail.com", "trustme", AuthenticationMethod.UsernameAndPassword)
