抓数据

做过股票的人都知道要选一个好股票往往要用到技术指标选股，而有时自己会有一些想法，想用其来挑选股票，并用历史数据进行校验，必须要有每日的数据，下面是我自己写的一个抓数据的C#代码。

 

 

using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;

namespace 股票技术分析{    public partial class Form3 : Form    {        string conn = System.Configuration.ConfigurationManager.ConnectionStrings["BusinessConnString"].ConnectionString;        string stockcode = "";        DataTable dt;        int Count = 0;        string beginday;        string endday;        public Form3()        {            InitializeComponent();        }

        private void Form3_Load(object sender, EventArgs e)        {            DataSet ds = Platform.Data.SqlHelper.ExecuteDataset(conn, CommandType.Text, "select * from StockCodeInformation where IsActive=0 order by stockcode");            dt = ds.Tables[0];            stockcode = dt.Rows[0]["stockcode"].ToString();

            beginday = (1991 ).ToString() + "-01-01";            endday = (1991 ).ToString() + "-12-31";            webBrowser1.Url = new Uri(@"http://app.finance.ifeng.com/hq/stock_daily.php?code=" + stockcode + "&begin_day=" + beginday + "&end_day=" + endday);        }

        private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)        {            string sql = "update StockCodeInformation set IsActive=1 where stockcode = '" + stockcode + "'";            Platform.Data.SqlHelper.ExecuteNonQuery(conn, CommandType.Text, sql);                       

            if (Count < dt.Rows.Count)             {                Count++;                stockcode = dt.Rows[Count]["stockcode"].ToString();                webBrowser1.Url = new Uri(@"http://app.finance.ifeng.com/hq/stock_daily.php?code=" + stockcode + "&begin_day=" + beginday + "&end_day=" + endday);            }        }    }}
