Question

所以我正在制作一个连接到颤抖的irc聊天的机器人。这是代码：

Console.WriteLine("Joining Room");
IrcClient irc = new IrcClient("irc.twitch.tv", 6667, "ScottBots", "oauth:asdasd");

irc.joinRoom("ScottBots");
Console.WriteLine("Joined Room");

int i = 0;

while (true)
{
    string message = irc.readMessage();
    if(message.Contains("!helps"))
    {
        irc.sendChatMessage("Welcome to ScottBots! Currently in development.");
    }
    Console.WriteLine("loop: " + i);
    i++;
}

看看真正的循环......一切都好吗？

现在看一下这个控制台应用程序给我的内容：

Joining Room
Joined Room
loop: 0
loop: 1
loop: 2
loop: 3
loop: 4
loop: 5
loop: 6
loop: 7
loop: 8
loop: 9

它只停在9？

许多人一直在问我的ircClient代码：

private string username;
    private string channel;

    private TcpClient tcpClient;
    private StreamReader inputStream;
    private StreamWriter outputSteam;

    public IrcClient(string ip, int port, string username, string password)
    {
        this.username = username;

        tcpClient = new TcpClient(ip, port);
        inputStream = new StreamReader(tcpClient.GetStream());
        outputSteam = new StreamWriter(tcpClient.GetStream());
        try
        {
            outputSteam.WriteLine("PASS " + password);
            outputSteam.WriteLine("NICK " + username);
            outputSteam.WriteLine("USER " + username + " 8 * :" + username);
            outputSteam.Flush();
        } catch (Exception e)
        {

        }

    }

    public void joinRoom(string channel)
    {
        try
        {
            this.channel = channel;
            outputSteam.WriteLine("JOIN #" + channel);
            outputSteam.Flush();
        }
        catch (Exception e)
        {
            Console.WriteLine("Failed to join room");
        }

    }

    public void sendIrcMessage(string message)
    {


        try
        {
            outputSteam.WriteLine(message);
            outputSteam.Flush();
        }
        catch (Exception e)
        {
            Console.WriteLine("failed to run sendIrcMessage() method");
        }
    }

    public void sendChatMessage(string message)
    {
        sendIrcMessage(":" + username + "!" + username + "@" + username + ".tmi.twitch.tv PRIVNSG #" + channel + " : " + message);
    }

    public string readMessage()
    {
        string message = inputStream.ReadLine();
        return message;
    }

看起来irc.SendChatMessage()或irc.ReadMessage()中的一个是blocking，也许当它用完缓冲的输入/输出并需要在套接字上等待时。

编辑：几乎可以肯定，irc.ReadMessage()电话正在阻止。它会针对Stream调用ReadLine()，而Stream又与TcpClient相关联。如果要构建IRC bot和测试装备，您可能希望查看线程和/或异步回调。以下是一个示例（与IRC无关）：http://sunildube.blogspot.ca/2011/12/asynchronous-tcp-client-easy-example.html

真正的循环不是无限的？
