[原][C#][winForm]分级基金折溢价WinForm网络计算器

分级基金折溢价WinForm网络计算器

通过子/母基金代码，从 [ 东方财富网，天天基金网，新浪 ] 抓取分级基金的子母基金数据（代码，名称，净值，价格），

并计算出子基金（A基金，B基金）以及母基金的溢价率与折价率，

便于投资/投机客从中套利。

数据通过网站获取，使用基金净值，非估值，一般晚间网站会更新当天基金净值，不可用于实时计算。

代码：

1.窗体如效果图

2.常用变量与数据抓取代码：

 namespace fundGetAndCal
 {
     public static class CONST
     {
         //获取母子基金代码
         public static string fundF10Url = "http://fund.eastmoney.com/f10/jbgk_{%fundCode%}.html";
         //获取净值
         public static string fundValUrl = "http://fund.eastmoney.com/{%fundCode%}.html";
         //获取价格
         public static string fundPriceUrl = "http://hq.sinajs.cn/?list={%fundAllCode%}";
         //母子基金列表
         public static List<string[]> allFunCodeLst;
         //读取完了
         public static bool okFlg = false;
         //状态显示文字
         public static string show = "就绪";
         public static int barMax = ;
         public static int barNow = ;

         public static string GetHtml(string url, Encoding encode)
         {
             string strBuff = "";//定义文本字符串，用来保存下载的html
             try
             {
                 HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(url);
                 HttpWebResponse webResponse = (HttpWebResponse)webRequest.GetResponse();
                 //若成功取得网页的内容，则以System.IO.Stream形式返回，若失败则产生ProtoclViolationException错 误。在此正确的做法应将以下的代码放到一个try块中处理。这里简单处理
                 Stream reader = webResponse.GetResponseStream();
                 ///返回的内容是Stream形式的，所以可以利用StreamReader类获取GetResponseStream的内容，并以StreamReader类的Read方法依次读取网页源程序代码每一行的内容，直至行尾（读取的编码格式：UTF8）
                 StreamReader respStreamReader = new StreamReader(reader,/*Encoding.UTF8*/encode);

                 strBuff = respStreamReader.ReadToEnd();
             }
             catch (Exception e)
             {
                 Console.Write(url+"\n"+e.Message);
             }
             return strBuff;
         }
     }
 }
