OpenPop.net获取实际消息文本

Question

我正在使用OpenPop.net来尝试从给定收件箱中的所有电子邮件中解析我们的链接。我找到了这个方法来获取所有的消息：

    public static List<OpenPop.Mime.Message> FetchAllMessages(string hostname, int port, bool useSsl, string username, string password)
    {
        // The client disconnects from the server when being disposed
        using (Pop3Client client = new Pop3Client())
        {
            // Connect to the server
            client.Connect(hostname, port, useSsl);

            // Authenticate ourselves towards the server
            client.Authenticate(username, password);

            // Get the number of messages in the inbox
            int messageCount = client.GetMessageCount();

            // We want to download all messages
            List<OpenPop.Mime.Message> allMessages = new List<OpenPop.Mime.Message>(messageCount);

            // Messages are numbered in the interval: [1, messageCount]
            // Ergo: message numbers are 1-based.
            // Most servers give the latest message the highest number
            for (int i = messageCount; i > 0; i--)
            {
                allMessages.Add(client.GetMessage(i));                    
            }

            client.Disconnect();

            // Now return the fetched messages
            return allMessages;
        }
    }

现在我试着遍历每条消息，但我似乎不知道该怎么做，到目前为止我的按钮是这样的：

    private void button7_Click(object sender, EventArgs e)
    {

        List<OpenPop.Mime.Message> allaEmail = FetchAllMessages("pop3.live.com", 995, true, "xxxxx@hotmail.com", "xxxxx");

        var message = string.Join(",", allaEmail);
        MessageBox.Show(message);
    }

如何遍历allaEmail中的每个条目，以便在MessageBox中显示它？

我可以从OpenPop主页上看到您使用的fetchAllEmail example。主页上也有一个类似的示例showing how to get body text。

你可能还想看看电子邮件实际上是如何构造的。email introduction的存在就是为了这个目的。

话虽如此，我会做一些类似于下面的代码。

private void button7_Click(object sender, EventArgs e)
{
    List<OpenPop.Mime.Message> allaEmail = FetchAllMessages(...);

    StringBuilder builder = new StringBuilder();
    foreach(OpenPop.Mime.Message message in allaEmail)
    {
         OpenPop.Mime.MessagePart plainText = message.FindFirstPlainTextVersion();
         if(plainText != null)
         {
             // We found some plaintext!
             builder.Append(plainText.GetBodyAsText());
         } else
         {
             // Might include a part holding html instead
             OpenPop.Mime.MessagePart html = message.FindFirstHtmlVersion();
             if(html != null)
             {
                 // We found some html!
                 builder.Append(html.GetBodyAsText());
             }
         }
    }
    MessageBox.Show(builder.ToString());
}

我希望这能对你有所帮助。请注意，还有用于OpenPop的online documentation。

我是这样做的：

string Body = msgList[0].MessagePart.MessageParts[0].GetBodyAsText();
            foreach( string d in Body.Split('\n')){
                Console.WriteLine(d);                    
            }

希望能有所帮助。

这个问题中的其他答案是不完整的和icorrect的，主要是因为他们从来没有使用FindAllTextVersions方法，这是至关重要的。

下面是获取实际正文内容的完整方法：

private static string GetMessageBodyAsText(Message message)
{
    try
    {
        List<MessagePart> list = message.FindAllTextVersions();

        // First let's try getting the plain text part:
        foreach (MessagePart part in list)
        {
            if (part != null)
            {
                return part.GetBodyAsText();
            }
        }

        // Now let's try getting the HTML part
        MessagePart html = message.FindFirstHtmlVersion();
        if (html != null)
        {
            return html.GetBodyAsText();
        }
        return null;
    }
    catch (Exception exc)
    {
        // Handle your exception here
        return null;
    }
}
