Question

我正在创建一个c＃windows应用程序，使用betfair exchange webservice显示当前的体育市场费率，我使用

getmarketpricescompressed（）

返回如下所示的价格字符串的方法：

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此字符串，现在我正在使用此代码：

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，但我观察到一些其他匹配的字符串更改，因此它生成异常， any1可以帮我用正确的代码解压缩这个字符串，我用Google搜索并发现了一个vb代码，这个代码不是很有用，

和顺便说一句，我想安排这样的数据：

Answer 1

请考虑以下事项：

a|b|c|d

在这里，你有四个块。但它不一定只有四个。它可以是两个，也可以是六个。

尝试通过迭代由

得到的字符串数组来实现它

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

像

这样的东西

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

猜测，我认为数据的组织方式如此

首先由:分隔，然后|分隔

106093239〜GBP〜ACTIVE〜0〜1 ~~真〜5.0〜1343114432333 ~~Ñ

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

414464〜2〜102181.96〜1.86 ~~~假~~~~   1.85〜2900.33〜L〜1〜1.84〜1831.59〜L〜2〜1.83〜1593.73〜1〜3〜   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~界定的

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

我认为价格行在元组4中由~分隔，就像这样

（价格）2.16（MatchAvailable）1036.19（类型）L（订单）1
  （价格）2.14（MatchAvailable）0097.18（类型）L（订单）2
  （价格）2.12（MatchAvailable）0005.00（Type）L（订购）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。

我将vb代码转换为c＃我自己，如果有人发现它有用，我会在这里发布：

using Microsoft.VisualBasic;
using System;
using System.Collections;

using System.Data;
using System.Diagnostics;

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

            _with1.bestPricesToLay = Prices(Part[2]);
        }
    }

    private stock.BFExchangeService.Price[] Prices(string PriceString)
    {
        string[] Field = null;
        stock.BFExchangeService.Price[] Price = null;
        int k = 0;
        int m = 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++) 
        {
            Price[i] = new stock.BFExchangeService.Price();
            var _with2 = Price[i];
            _with2.price = Convert.ToInt32(Field[k + 0]);
            //Assign price data
            _with2.amountAvailable = Convert.ToInt32(Field[k + 1]);
            _with2.betType = (stock.BFExchangeService.BetTypeEnum)Enum.Parse(typeof(stock.BFExchangeService.BetTypeEnum), Field[k + 2], true);
            _with2.depth = Convert.ToInt32(Field[k + 3]);
            k += 4;
        }
        return Price;
        //Return the array of prices
    }

    }
}

有没有人有c＃代码来使用betfair api？
