数据采集（天天，百度百家）

爆文采集系统后台数据支撑：百度百家以及天天快报等等。。

 

简单采集过程，不再复述。

重点放在新学的线程以及桌面应用程序：

1、线程部分，   开始、暂停、继续、结束

　　　　 public enum opState
        {
            none,   //无操作
            pause,  //暂停
            go_on,  //继续
            stop    //停止
        }
        private Thread myThread = null;
        private bool myThreadRun = false;
        private opState state = opState.none;
        private delegate void ShowMsgHandler(string msg);
        public Form1()
        {
            InitializeComponent();
        }

        /// <summary>
        /// 开始
        /// </summary>
        private void button1_Click(object sender, EventArgs e)
        {
            if (myThread == null || myThread.ThreadState == ThreadState.Stopped)
            {
                myThreadRun = true;
                myThread = new Thread(new ThreadStart(runPro));
                myThread.IsBackground = true;
                myThread.Start();
            }
            else
            {
                myThreadRun = false;
            }
        }

        public void runPro()
        {
            for (int i = 0; i < 10000; i++)
            {
                //状态开关控制
                switch (state)
                {
                    case opState.pause:
                        i--;
                        continue;
                    case opState.go_on:
                        break;
                    case opState.none:
                        break;
                    case opState.stop:
                        return;
                }
                if (this.InvokeRequired)
                {
                    this.Invoke(new ShowMsgHandler(ShowMsg), i.ToString());
                }
                else
                {
                    ShowMsg(i.ToString());
                }
                //Thread.Sleep(100);
            }
        }
        private void ShowMsg(string msg)
        {
            this.textBox1.AppendText(msg + "
");
        }

        /// <summary>
        /// 暂停
        /// </summary>
        private void button2_Click(object sender, EventArgs e)
        {
            state = opState.pause;
        }

        /// <summary>
        /// 继续
        /// </summary>
        private void button3_Click(object sender, EventArgs e)
        {
            state = opState.go_on;
        }

        /// <summary>
        /// 停止
        /// </summary>
        private void button4_Click(object sender, EventArgs e)
        {
            state = opState.stop;
            myThreadRun = false;
        }

2、窗体应用程序

2.1、异步加载输出

this.Invoke(new Action(() =>
2 {
　　label2.Text = subject_name;
　　  textBox.AppendText("【" + DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss") + "】 ----添加新作者：" + writer_name + "
" + "
");
    textBox.ScrollToCaret();//下拉框
 }));

2.2、时间插件

ps:记得修改插件属性Interval的值为1000

private void timer1_Tick(object sender, EventArgs e)
        {
            Second_++;
            if (Second_ == 60)
            {
                Second_ = 0;
                Minute_++;
            }
            if (Minute_ == 60)
            {
                Minute_ = 0;
                Hour_++;
            }
            label7.Text = Hour_ + "：" + Minute_ + "：" + Second_;
        }
