C＃替換String.Split

Question

我有一個字符串格式 「10,2/20,5/50,3」

這些是每一個球員的勝利。 「roomPrize，wins/nextRoomPrize，wins」等

我想出瞭如何閱讀它，但我想改變一些roomPrize的勝數。我來到這裏了。

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 
    } 
} 

感謝

如果我明白你的問題好了，你想做到以下幾點：

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

爲了實現這一點，你就需要拆分值，然後重新創建它（例如Join）並將其放回原始數組中。

下面應該做的伎倆：

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); 
} 

編輯使用以下值：

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

，並通過在上面的代碼的末尾添加var output = String.Join("/", winSplits);，你會得到一個字符串輸出：

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

請參閱下面的代碼mplete例如：

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"

你應該先重構的數據反序列化到一些球員的對象，改變它的勝利計數，然後將其序列化回：

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); 
     } 
    } 
} 

它更代碼，但更容易維護。
