基金净值估算程序 C#实现

原来天天基金或者支付宝上都能直接看到当天的基金估值,从今天开始基金的当天估值全部下架了(真是把股民/基民当韭菜了,而且是套着麻袋割)
为了能实时看到基金的净值估值,只能自己通过基金公布的重仓股票份额自行估算涨跌。
于是就有了下面的代码,C#实现 Linqpad版,基金的持股份额保存在SQLite数据库中,其实也可以通过查询获取。
var jj = new JiJin("002910"); var stocks = Stocks.Select(x=>x); foreach (var item in stocks) { var change = GetStockChange(item.Stockname); jj.Stock[item.Stockname] = ((double)item.Percentage, change*0.01); } jj.Calculate(); jj.Dump(); $"{DateTime.Now.ToShortDateString()} 基金002910的净值估计变动{jj.TotalChange*100}%".Dump(); double GetStockChange(string code) { double change = 0; var wc = new WebClient(); wc.Headers.Add("User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/115.0.0.0 Safari/537.36 Edg/115.0.1901.183"); var str = wc.DownloadString("http://qt.gtimg.cn/q=" + code); var data = str.Split("~"); change = Convert.ToDouble(data[32].Trim()); return change; } class JiJin { public string Name { get; private set; } public Dictionary<string, (double, double)> Stock {get; set;} = new(); public double TotalChange {get; set;} public JiJin(string name) { Name = name; } public double Calculate() { double total=0; double totalpercent=0; double totalchange=0; double count=0; foreach (var item in Stock) { total += item.Value.Item1 * item.Value.Item2; totalpercent += item.Value.Item1; totalchange += item.Value.Item2; count++; } totalchange /= count; total += (1-totalpercent)*totalchange; TotalChange = total; return TotalChange; } }

改进了一下,直接输入基金代码可以自动查询持仓并计算净值。
通过解析天天基金的网页进行计算。
var jj = new JiJin("012414"); jj.GetChiCang(); jj.Calculate(); $"{DateTime.Now.ToShortDateString()} 基金{jj.Name}的净值估计{jj.TotalChange*100}%".Dump(); class JiJin { public string Name { get; private set; } public Dictionary<string, (double, double)> Stock { get; set; } = new(); public double TotalChange { get; set; } public JiJin(string name) { Name = name; } public double Calculate() { double total = 0; double totalpercent = 0; double totalchange = 0; double count = 0; foreach (var item in Stock) { total += item.Value.Item1 * item.Value.Item2; totalpercent += item.Value.Item1; totalchange += item.Value.Item2; count++; } totalchange /= count; total += (1 - totalpercent) * totalchange; TotalChange = total; return TotalChange; } public void GetChiCang() { var wc = new WebClient(); wc.Headers.Add("User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/115.0.0.0 Safari/537.36 Edg/115.0.1901.183"); var str = wc.DownloadString($"http://fund.eastmoney.com/{Name}.html"); HtmlDocument doc = new HtmlDocument(); doc.LoadHtml(str); var node = doc.DocumentNode.SelectSingleNode("//*[@id='position_shares']/div[1]/table"); var content = node.InnerText; var c = content.Split(" ").Where(x => x.Length > 0); var list = c.ToArray()[4..]; for (var i=0; i<list.Length;i++) { if (list[i].EndsWith("%") && list[i+1].EndsWith("%")) { Stock[list[i-1]] = (Convert.ToDouble(list[i][..^1])*0.01, Convert.ToDouble(list[i+1][..^1])*0.01); } } } }
2023/7/24 星期一 基金012414的净值估计-1.1309255000000003%
对比实际当天净值,基本上还可以。

aardio不是可以直接调用C#的类的吗?
import console; console.setTitle("MyJiJin"); import dotNet; var dll = dotNet.load("\res\JiJin.dll"); var JiJin = dll.import("JiJin"); var jj = JiJin.JiJin("002910"); jj.GetChiCang(); jj.Calculate(); console.log(jj.TotalChange); console.pause();

换了个异步写法,调用天天基金的api接口并解析json列表
var myjj = new JiJin("002910"); myjj.Adjustment = 0.9; myjj.GetStocks(); myjj.Calculate(); myjj.Dump(); public class JiJin { public string _Code { get; private set; } public string _Name { get; private set; } public double TotalChange {get; set;} public double Adjustment {get; set;} = 1; public List<Dictionary<string, (double, double)>> Stocks = new List<Dictionary<string, (double, double)>>(); public JiJin (string code) { _Code = code; } JToken GetChiCang() { var wc = new HttpClient(); wc.DefaultRequestHeaders.Add("User-Agent", "EMProjJijin/6.2.8 (iPhone; iOS 13.6; Scale/2.00)"); wc.DefaultRequestHeaders.Add("GTOKEN", "98B423068C1F4DEF9842F82ADF08C5db"); wc.DefaultRequestHeaders.Add("clientInfo", "ttjj-iPhone10,1-iOS-iOS13.6"); wc.DefaultRequestHeaders.Add("ContentType", "application/x-www-form-urlencoded"); wc.DefaultRequestHeaders.Add("Host", "fundmobapi.eastmoney.com"); wc.DefaultRequestHeaders.Add("Referer", "https://mpservice.com/516939c37bdb4ba2b1138c50cf69a2e1/release/pages/FundHistoryNetWorth"); var resp = wc.GetStringAsync($"https://fundmobapi.eastmoney.com/FundMNewApi/FundMNInverstPosition?FCODE={_Code}&OSVersion=14.3&appVersion=6.3.8&deviceid=3EA024C2-7F22-408B-95E4-383D38160FB3&plat=Iphone&product=EFund&serverVersion=6.3.6&version=6.3.8"); return JConstructor.Parse(resp.Result)["Datas"]["fundStocks"]; } async Task<double> GetStockChange(string code) { double change = 0; var wc = new HttpClient(); wc.DefaultRequestHeaders.Add("User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/115.0.0.0 Safari/537.36 Edg/115.0.1901.183"); var bytes = await wc.GetByteArrayAsync("http://qt.gtimg.cn/q=" + code); var str = Encoding.UTF8.GetString(bytes); var data = str.Split("~"); change = Convert.ToDouble(data[32].Trim()); return change; } public void GetStocks() { var chicang = GetChiCang(); foreach (var each in chicang) { var stock = ((string)each["GPDM"]).StartsWith("6") ?

回复#8 @鸿湖重工业株式会社 :
这个还要看你调用的dll,有些比如申明了允许外部调用,有些可能是私有的,还有些可能是受保护的,或者是只读或者只写的属性。
例如,上面的这个类
public class JiJin { public string _Code { get; private set; } public string _Name { get; private set; } public double TotalChange {get; set;} public double Adjustment {get; set;} = 1; public List<Dictionary<string, (double, double)>> Stocks = new List<Dictionary<string, (double, double)>>(); public JiJin (string code) { _Code = code; } ...
这个类的“_Code”的写属性就是私有的,只能在创建时修改“_Code”的值,外部调用时只能是只读的,你要写就会报错。

估计的净值,难免是有误差,但是总好过被套着麻袋割韭菜
