Question

我正在为自己的lib工作pop3，因为我没有在这里建议的那些找到我需要的东西。我的问题是，当打开一条消息时它只能读取某一行（通常是文本中的一个链接）并且它会停止，循环但不会崩溃。代码是：

Data = "RETR 1" + CRLF;
szData = System.Text.Encoding.ASCII.GetBytes(Data.ToCharArray());
NetStrm.Write(szData, 0, szData.Length);
txtLog.Text += RdStrm.ReadLine() + CRLF;
for (int i = 0; i < 33; i++)
{

    txtLog.Text += RdStrm.ReadLine() + CRLF;
}


string szTemp;
szTemp = RdStrm.ReadLine();
// here it's supposed to start reading the actual message
while(szTemp != "-")
    {

        txtLog.Text += szTemp + CRLF;
        szTemp = RdStrm.ReadLine();

    }

Match reg1 = Regex.Match(ifOk, "OK(.*)", RegexOptions.IgnoreCase);

if (reg1.Success)
{
    txtLog.Text += "Ready To Start!\r\n";

    Data = "USER XXXX" + CRLF;
    szData = System.Text.Encoding.ASCII.GetBytes(Data.ToCharArray());
    NetStrm.Write(szData, 0, szData.Length);
    txtLog.Text += RdStrm.ReadLine() + CRLF;

    Data = "PASS XXXX" + CRLF;
    szData = System.Text.Encoding.ASCII.GetBytes(Data.ToCharArray());
    NetStrm.Write(szData, 0, szData.Length);
    txtLog.Text += RdStrm.ReadLine() + CRLF;

    Data = "STAT" + CRLF;
    szData = System.Text.Encoding.ASCII.GetBytes(Data.ToCharArray());
    NetStrm.Write(szData, 0, szData.Length);
    txtLog.Text += RdStrm.ReadLine() + CRLF + CRLF + CRLF + CRLF + CRLF;

    Data = "RETR 1" + CRLF;
    szData = System.Text.Encoding.ASCII.GetBytes(Data.ToCharArray());
    NetStrm.Write(szData, 0, szData.Length);
    txtLog.Text += RdStrm.ReadLine() + CRLF;

    string szTemp;

    szTemp = RdStrm.ReadLine();

    // POP3 uses . as the end of a message
    while(szTemp != ".")
    {                   
        txtLog.Text += szTemp + CRLF;
        szTemp = RdStrm.ReadLine();                                               
    }              
}

解决它，看起来互联网需要一个好的，开源的，易于修改的lib，这就是我接下来要做的事情。感谢大家。现在完美运作

如果另一端的服务返回以CRLF结尾的行，那么从Readline获得的行将在结尾处具有CR。所以返回的字符串将永远是！=“ - ”。

带有POP3的TcpClient响应流，无法读取多行
