我们“老板”让我记录 上面的长江水文数据！此网站有个变态的事情就是数据只是在一段时间内才有，例如：我是要记录早晨8时的数据，而此数据一般只出现在早晨8时和早晨9时之间，一旦到了9时之后，数据可能就要更新了，最开始的时候，我都是早晨起来用 Weibo 截图发布来记录，知道有一天我突发奇想，我还是写个程序吧，于是此程序就出现了！
首先看看预览吧！
基本思路：
- 提取网页中的文字，通过特征字符来查找需要的信息！
- 将查找的有用信息添加到 List 中！
- 将 List 中的数据导入到 DataGridView 或是 Excel 中！
遇到的问题：
- 刷新网页的时候，可能弹出广告，就不可以正确提取数据！
- 确定是否都是8时的数据！
- 为了尽量缩短刷新页面的次数，测试时间在 8:30 - 9:00 之间，若是此段时间一直未出现都是8时的情况，需要另想办法！
- C# 对于 Excel 的操作！
具体实现步骤如下：
① 全局变量：
public struct Info //用来记录表格中的四个属性数据{ public string name; public string date; public string water; public string stream;}//引用：using Excel = Microsoft.Office.Interop.Excel;Excel.Application ex = new Excel.Application();Excel.Workbook eWorkbook;Excel.Worksheet eWorksheet;int countRecorderDay = 0; //用来记录白天的记载次数int countRecorderNight = 0; //用来记录夜间的记录次数int count = 0; //倒计时来用string saveFilePath = Environment.CurrentDirectory + @"\长江水文\长江水文.xlsx"; //Excel的文件地址 ② 添加控件：
timer1：用来记录总时间，每隔1分钟记录一次，到达 8:30 启动 timer2；
timer2：记录局部操作，开始刷新网页；
timer3：倒计时；
notifyIcon1：用来显示在任务栏中的通知；
contextMenuStrip2：用来显示通知的右键菜单。
③ 具体代码：
