Question

我正在将文件（php）解析为C＃中的列表，以便我可以使用它来完成任务。我之前在PHP中已经完成了它，但它的工作速度非常慢，所以我正在尝试制作一个C＃winform应用程序。

这是我在C＃中已有的代码：

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

namespace g7_product_parser
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        public void log(String msg)
        {
            textBox1.AppendText(msg + "\r\n\r\n");
        }

        public string[] parseLine(String regel)
        {
            string[] parsed;
            parsed = new string[2];
            regel = regel.Replace("array(", "");
            regel = regel.Replace("),", "");
            regel = regel.Replace(")", "");
            string[] temp = regel.Split(',');
            foreach (string part in temp)
            {
                string[] part2 = Regex.Split(part, "=>");
                // log(String.Join(",", part2));
                if (part2[0].Replace("'", "").Trim() == "keyword_uid")
                {
                    parsed[1] = part2[1].Replace("'", "").Trim();
                }
                else if (part2[0].Replace("'", "").Trim() == "product_uid")
                {
                    parsed[0] = part2[1].Replace("'", "").Trim();
                }
            }
            return parsed;
        }

        private void button1_Click(object sender, EventArgs e)
        {
            String startTime = DateTime.Now.ToString("HH:mm:ss tt");
            log("Begin!");
            string[] lines = System.IO.File.ReadAllLines("tx_ttproductsv2_keywords_in_products.php");
            List<string> entrys = new List<string>();
            foreach (string line in lines)
            {
               // parseLine(line);
                log(String.Join(",",parseLine(line)));

                Application.DoEvents();
            }



            String endTime = DateTime.Now.ToString("HH:mm:ss tt");
            String totalTime = (DateTime.Parse(endTime) - DateTime.Parse(startTime)).ToString();
            log("Klaar!");
            log("Start Tijd: " + startTime + "\r\nEind Tijd: " + endTime + "\r\nTotale Tijd: " + totalTime);
        }


    }
}

要解析的文件如下所示：

array('uid' => '1','pid' => '2','keyword_uid' => '1','product_uid' => '1','amount' => '15','in_title' => '0'),
array('uid' => '2','pid' => '2','keyword_uid' => '2','product_uid' => '1','amount' => '12','in_title' => '0'),
array('uid' => '3','pid' => '2','keyword_uid' => '3','product_uid' => '1','amount' => '12','in_title' => '0'),
array('uid' => '4','pid' => '2','keyword_uid' => '4','product_uid' => '1','amount' => '9','in_title' => '0'),
array('uid' => '5','pid' => '2','keyword_uid' => '5','product_uid' => '1','amount' => '18','in_title' => '0'),
array('uid' => '6','pid' => '2','keyword_uid' => '6','product_uid' => '1','amount' => '6','in_title' => '0'),
array('uid' => '7','pid' => '2','keyword_uid' => '7','product_uid' => '1','amount' => '6','in_title' => '0'),
array('uid' => '8','pid' => '2','keyword_uid' => '8','product_uid' => '1','amount' => '6','in_title' => '0'),
array('uid' => '9','pid' => '2','keyword_uid' => '9','product_uid' => '1','amount' => '79','in_title' => '1'),
array('uid' => '10','pid' => '2','keyword_uid' => '10','product_uid' => '1','amount' => '6','in_title' => '0'),
array('uid' => '11','pid' => '2','keyword_uid' => '11','product_uid' => '1','amount' => '6','in_title' => '0'),
array('uid' => '12','pid' => '2','keyword_uid' => '12','product_uid' => '1','amount' => '6','in_title' => '0'),
array('uid' => '13','pid' => '2','keyword_uid' => '13','product_uid' => '1','amount' => '6','in_title' => '0'),
array('uid' => '14','pid' => '2','keyword_uid' => '14','product_uid' => '1','amount' => '6','in_title' => '0'),
array('uid' => '15','pid' => '2','keyword_uid' => '15','product_uid' => '1','amount' => '15','in_title' => '0'),
array('uid' => '16','pid' => '2','keyword_uid' => '16','product_uid' => '1','amount' => '12','in_title' => '0'),
array('uid' => '17','pid' => '2','keyword_uid' => '17','product_uid' => '1','amount' => '12','in_title' => '0'),
array('uid' => '18','pid' => '2','keyword_uid' => '18','product_uid' => '1','amount' => '6','in_title' => '0'),
array('uid' => '19','pid' => '2','keyword_uid' => '19','product_uid' => '1','amount' => '15','in_title' => '1'),
array('uid' => '20','pid' => '2','keyword_uid' => '20','product_uid' => '1','amount' => '6','in_title' => '0'),
array('uid' => '21','pid' => '2','keyword_uid' => '21','product_uid' => '1','amount' => '15','in_title' => '0'),
array('uid' => '22','pid' => '2','keyword_uid' => '22','product_uid' => '1','amount' => '21','in_title' => '0'),
array('uid' => '23','pid' => '2','keyword_uid' => '23','product_uid' => '1','amount' => '12','in_title' => '0'),

我有一些像这样的PHP代码：

require_once 'export/tx_ttproductsv2_keywords_in_products_part.php';
$sql = new Sql;
    $tagList = array();
    $counter = 0;
    $counter2 = 0;
    $counter3 = 0;

    foreach ($tx_ttproductsv2_keywords_in_products as $key => $value) {
        $keywordsList = $sql -> getKeyWords($value['keyword_uid']);
        foreach ($keywordsList as $key2 => $value2) {
            if(isset($tagList[$value['product_uid']])){
                $tagList[$value['product_uid']] .= ", " . $value2['keyword'];
            }else{
                $tagList[$value['product_uid']] = $value2['keyword'];
            }
        }
    }

以这种方式（在PHP中），我检查数组中的条目是否已经被激活，如果这是真的，则追加，或者创建一个新条目。

我的问题是：我怎样才能在C＃中做到这一点。我认为我必须使用一个列表，但我真的不知道究竟是怎么回事。

Answer 1

我编写了一个快速而又脏的控制台程序，将其转换为数组。看看你是否可以根据自己的目的进行修改......如果没有，请详细说明你需要它做什么。

（注意：这是一个快速的工作，并不是处理这个问题的最有效方法。）

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;

namespace simplearraything
{
class myarrayitem
{
    public int uid;
    public int pid;
    public int keyword_uid;
    public int product_uid;
    public int amount;
    public int in_title;
}
class Program
{
    static void Main(string[] args)
    {
        //array('uid' => '23','pid' => '2','keyword_uid' => '23','product_uid' => '1','amount' => '12','in_title' => '0'),
        string Original = File.ReadAllText("array.txt").Replace("array('uid' => '", "").Replace(
            "','pid' => '", "/").Replace("','keyword_uid' => '", "/").Replace("','product_uid' => '", "/").Replace(
            "','amount' => '", "/").Replace("','in_title' => '", "/").Replace("'),", "").Replace("\r","");
        string[] lines = Original.Split('\n');
        List<myarrayitem> mystuff = new List<myarrayitem>();
        for (int i = 0; i < lines.Length; i++)
        {
            string[] thisitem = lines[i].Split('/');
            myarrayitem item = new myarrayitem();
            item.uid = int.Parse(thisitem[0]);
            item.pid = int.Parse(thisitem[1]);
            item.keyword_uid = int.Parse(thisitem[2]);
            item.product_uid = int.Parse(thisitem[3]);
            item.amount = int.Parse(thisitem[4]);
            item.in_title = int.Parse(thisitem[5]);
            mystuff.Add(item);
        }


        // Now, output it to prove accuracy:
        for (int i = 0; i < lines.Length; i++)
        {
            Console.WriteLine("UID:" + mystuff[i].uid.ToString() + "/PID:" + mystuff[i].pid.ToString() + "/KEYWORD_UID:" + mystuff[i].keyword_uid.ToString() +
                "/PRODUCT_UID:" + mystuff[i].product_uid.ToString() + "/amount:" + mystuff[i].amount.ToString() + "/in_title:" + mystuff[i].in_title.ToString());
        }
        Console.Read();
    }
}
}

回应评论：

List<myarrayitem> items new List<myarrayitem>();
for (int i = 0;i < mystuff.Count;i++)
{
      if (mystuff[i].product_uid == PRODUCT_UID_HERE)
      {
            items.add(mystuff[i]);
            // Or, instead of this items List, you could just do whatever you wanted to do with the items right here.
      }
}

试试这个：

获取Newtonsoft.Json
将以下类添加到您的代码中：

public class DataArray {
  public string uid { get; set; }
  public string pid { get; set; }
  public string keyword_uid { get; set; }
  public string product_uid { get; set; }
  public string amount { get; set; }
  public string in_title { get; set; }
}

public class RootObject {
  public DataArray DataArray { get; set; }
}

将文件加载到名为toProcess的String中，然后运行以下命令：

//接下来的4行将该数据转换为JSON格式
      toProcess = toProcess.Replace（“array（”，“{\”DataArray \“：{”）;
      toProcess = toProcess.Replace（“）”，“}}”）;
      toProcess = toProcess.Replace（“'”，“\”“）;
      toProcess =“[”+ toProcess.Replace（“=＆gt;”，“：”）+“]”;
List<RootObject> data = JsonConvert.DeserializeObject<List<RootObject>>(toProcess); 

foreach ( RootObject d in data ) {    
  // do something here like..
  if (d.DataArray.uid == "1") {
      //
  }
}

将文件解析为列表
