c# - 有没有人有使用 betfair api 的 c# 代码？

Question

我正在创建 ac# windows 应用程序以使用 betfair 交换网络服务显示当前的体育市场价格，我使用了

getmarketpricescompressed()

方法返回一个价格字符串，如下所示：

106093239~GBP~ACTIVE~0~1~~true~5.0~1343114432333~~N:7337~1~6992.56~2.16~~~false~~~~|2.16~1036.19~L~1~2.14~97.18~L~2~2.12~5.0~L~3~|2.18~467.36~B~1~2.2~34.12~B~2~2.22~162.03~B~3~:414464~2~102181.96~1.86~~~false~~~~|1.85~2900.33~L~1~1.84~1831.59~L~2~1.83~1593.73~L~3~|1.86~58.83~B~1~1.87~1171.77~B~2~1.88~169.15~B~3~

我不知道如何正确解压缩这个字符串，现在我正在使用这个代码：

GetMarketPricesCompressedReq price_req1 = new GetMarketPricesCompressedReq();
            price_req1.header = header2;
            price_req1.marketId = marketid_temp;
            price_req1.currencyCode = "GBP";
            GetMarketPricesCompressedResp price_resp = new GetMarketPricesCompressedResp();
            price_resp = bfg2.getMarketPricesCompressed(price_req1);
            //MessageBox.Show(price_resp.errorCode.ToString());
            //richTextBox1.Text = "";
            //richTextBox1.Text = price_resp.marketPrices;
            string prices = price_resp.marketPrices;
            richTextBox1.Text = price_resp.marketPrices;
            string[] ab1 = prices.Split('|');
            string[] temp = ab1[1].Split('~');
            textBox3.Text = temp[0];
            textBox4.Text = temp[4];
            textBox5.Text = temp[8];
            temp = ab1[2].Split('~');
            textBox6.Text = temp[0];
            textBox7.Text = temp[4];
            textBox8.Text = temp[8];
            temp = ab1[3].Split('~');
            textBox9.Text = temp[0];
            textBox10.Text = temp[4];
            textBox11.Text = temp[8];
            temp = ab1[4].Split('~');
            textBox12.Text = temp[0];
            textBox13.Text = temp[4];
            textBox14.Text = temp[8];
            if (ab1.Length >5)
            {
                temp = ab1[5].Split('~');
                textBox15.Text = temp[0];
                textBox16.Text = temp[4];
                textBox17.Text = temp[8];
                temp = ab1[6].Split('~');
                textBox18.Text = temp[0];
                textBox19.Text = temp[4];
                textBox20.Text = temp[8];
            }

它适用于一些匹配项，但我观察到其他一些匹配项的字符串更改，因此会产生异常，any1 可以帮助我使用正确的代码来解压这个字符串，我已经用谷歌搜索它并找到了一个 vb 代码，它不是很有用，

顺便说一句，我想以这样的方式排列数据：

Answer 1

考虑以下：

a|b|c|d

在此，您有四个块。但不一定只有四个。可以是两个，也可以是六个。

尝试通过迭代你得到的字符串数组来解决它

string[] ab1 = prices.Split('|');

就像是

foreach(var stringChunk in ab1)
{
    string[] temp = stringChunk.Split('~');
    // use the strings here as you please
}

考虑使用更动态的方法来呈现数据，使用基于行的重复控件而不是静态文本框。=)

Answer 2

只是猜测，我认为数据是这样组织的

首先分隔:然后|我们得到

106093239~GBP~ACTIVE~0~1~~true~5.0~1343114432333~~N

7337~1~6992.56~2.16~假~~~~
2.16~1036.19~L~1~2.14~97.18~L~2~2.12~5.0~L~3~ 2.18~467.36~B~1~2.2~34.12 ~B~2~2.22~162.03~B~3~

414464~2~102181.96~1.86~false~~~~ 1.85~2900.33~L~1~1.84~1831.59~L~2~1.83~1593.73~L~3~1.86~58.83~B~1~1.87~1171.77 ~B~2~1.88~169.15~B~3~

我认为第一行显然是一个标题，第一个数字可能是市场 ID。同样，每个后续部分的第一部分是行标识符。~由类似的东西分隔

(SelectionId)7337 (Order)1 (TotalMatched?)6992.56 (EvenPoint)2.16 (???)false

我认为价格行由 4 元组分隔~，就像这样

(Price)2.16 (MatchAvailable)1036.19 (Type)L (Order)1
(Price)2.14 (MatchAvailable)0097.18 (Type)L (Order)2
(Price)2.12 (MatchAvailable)0005.00 (Type)L (Order)3

例如。

为了测试我的猜测，我必须与他们网站上的 BetFair 渲染进行比较。

我自己将 vb 代码转换为 c#，如果有人觉得它有用，我将其发布在这里：

using Microsoft.VisualBasic;
using System;
using System.Collections;
using System.Collections.Generic;
using System.Data;
using System.Diagnostics;

        Field = Mprices[0].Replace("\\~", "-").Split('~');
        //Split market data fields
        marketId = Convert.ToInt32(Field[0]);
        //Assign the market data

        }
    }

    private stock.BFExchangeService.Price[] Prices(string PriceString)
    {
        string[] Field = null;

        int k = 0;

        Field = PriceString.Split('~');
        //Split price fields
        m = (Field.Length / 4) - 1;
        //m = number of prices - 1 
         // ERROR: Not supported in C#: ReDimStatement

        for (int i = 0; i <= m; i++)

            k += 4;
        }
        return Price;
        //Return the array of prices
    }

    }
