Question

我正在使用此代码使用POP3连接到我的Exchange服务器。

我正在尝试检索一个基本上没有被阅读过的电子邮件的收件箱，但我只是得到了一堆胡言乱语和阅读电子邮件。

你能帮我修改我的代码，只是阅读最新的消息。

Try
    tcpClient.Connect(hostName, 110)
    Dim networkStream As NetworkStream = tcpClient.GetStream()
    Dim bytes(tcpClient.ReceiveBufferSize) As Byte
    Dim sendBytes As Byte()

    networkStream.Read(bytes, 0, CInt(tcpClient.ReceiveBufferSize))

    sendBytes = Encoding.ASCII.GetBytes("User " + userName + vbCrLf)
    networkStream.Write(sendBytes, 0, sendBytes.Length)

    sTemp = networkStream.Read(bytes, 0, CInt(tcpClient.ReceiveBufferSize))

    sendBytes = Encoding.ASCII.GetBytes("Pass " + userPassword + vbCrLf)
    networkStream.Write(sendBytes, 0, sendBytes.Length) 

    sTemp = networkStream.Read(bytes, 0, CInt(tcpClient.ReceiveBufferSize))

    sendBytes = Encoding.ASCII.GetBytes("STAT" + vbCrLf)
    networkStream.Write(sendBytes, 0, sendBytes.Length)

    sTemp = networkStream.Read(bytes, 0, CInt(tcpClient.ReceiveBufferSize))

    sendBytes = Encoding.ASCII.GetBytes("RETR " + messageNumber + vbCrLf)
    networkStream.Write(sendBytes, 0, sendBytes.Length)

    networkStream.Read(bytes, 0, CInt(tcpClient.ReceiveBufferSize))
    returnMessage = Encoding.ASCII.GetString(bytes)
    EmailContent.Text = returnMessage

    sendBytes = Encoding.ASCII.GetBytes("QUIT" + vbCrLf)
    networkStream.Write(sendBytes, 0, sendBytes.Length)

    tcpClient.Close()
Catch ex As Exception
    EmailContent.Text = "Could not retrieve email or your inbox is empty"
End Try

当我使用top而不是retr时，我得到了这个

我不知道它是否适合您（必须使用Exchange 2007或2010），但我在最近的一些项目中使用Exchange Web Services并且运行良好。
