Question

我有一个这种格式的字符串＆＃34; 10,2 / 20,5 / 50,3＆＃34;

这些都是每个球员的胜利。＆＃34; roomPrize，胜/ nextRoomPrize，胜＆＃34;等

我想出了如何阅读它，但我想改变一些roomPrize的胜利数量。我到目前为止。

winsRawData = getStatW.text; //That is the wins string formated as explained above

string[] winSplits = winsRawData.Split('/');

for(int i = 0; i < winSplits.Length; i++)
{
    if(winSplits[i].Split(',')[0] == room.ToString()) //room is the roomPrize that i want to affect
    {
        //newWins is the new win count that I want to update with
        //winSplits[i].Split(',')[1] == newWins;  <-- I just need to do that
    }
}

如果我理解你的问题，你想做以下事情：

winSplits[i].Split(',')[1] = newWins;

为了实现这一点，您需要拆分该值，然后重新创建它（例如，加入）并将其放回原始数组中。

以下应该可以解决问题：

winsRawData = getStatW.text; //That is the wins string formated as explained above

string[] winSplits = winsRawData.Split('/');

for (int i = 0; i < winSplits.Length; i++)
{
    var dataArray = winSplits[i].Split(',');
    if (dataArray[0] == room.ToString()) //room is the roomPrize that i want to affect
    {
        // sets the new value.
        dataArray[0] = newWins;
    }

    // finalize by recreating the string and push it back to the original array
    winSplits[i] = String.Join(",", dataArray);
}

修改使用以下值：

var winsRawData = "10,2/20,5/50,3";
int room = 10;
int newWins = 100;

通过在上面的代码末尾添加var output = String.Join("/", winSplits);，您将得到一个字符串输出：

"100,2/20,5/50,3"

请参阅以下代码以获取完整示例：

string[] winSplits = winsRawData.Split('/');


for (int i = 0; i < winSplits.Length; i++)
{
    var dataArray = winSplits[i].Split(',');
    if (dataArray[0] == room.ToString()) //room is the roomPrize that i want to affect
    {
        // sets the new value.
        dataArray[0] = newWins.ToString();
    }

    // finalize by recreating the string and push it back to the original array
    winSplits[i] = String.Join(",", dataArray);
}

var output = String.Join("/", winSplits); // = "100,2/20,5/50,3"

你应该首先重构将数据反序列化为一些Player对象，更改它的wins count然后序列化它：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            // Raw data
            string rawData = "10,2/20,5/50,3";

            // First split
            string[] playersRaw = rawData.Split('/');

            // Initialize a collection for the player objects
            var players = new List<Player>();

            // Iterates over the splitted players data
            foreach (var playerRaw in playersRaw)
            {
                // Deserialize each player 
                var playerDeserialized = Player.Deserialize(playerRaw);

                // Store the player data into the players collection
                if (playerDeserialized != null)
                    players.Add(playerDeserialized);
            }

            // Seeks for player with room prize 10
            foreach (var player in players)
            {
                if (player.RoomPrize == 10)
                    // Increments players data wins count
                    player.Wins += 1;
            }

            // Updates the raw data serializing all players back again
            rawData = string.Join("/", Array.ConvertAll(players.ToArray(), (p) => p.Serialize()));

            Console.WriteLine(rawData);

            Console.ReadLine();
        }
    }

    class Player
    {
        public int RoomPrize { get; set; }

        public int Wins { get; set; }

        public static Player Deserialize(string data, char separator = ',')
        {
            Player player = null;
            string[] splittedData = new string[] { };

            if (!string.IsNullOrEmpty(data) && (splittedData = data.Split(separator)).Length == 2)
            {
                int roomPrize = 0, wins = 0;
                if (int.TryParse(splittedData[0], out roomPrize) && int.TryParse(splittedData[1], out wins))
                {
                    player = new Player();
                    player.RoomPrize = roomPrize;
                    player.Wins = wins;
                }
            }

            return player;
        }

        public string Serialize()
        {
            return string.Format("{0},{1}", this.RoomPrize, this.Wins);
        }
    }
}

代码更多，但更容易维护。
