構建ID的字典，鍵值對

Question

我交流＃初學者開發 我想模擬 獨特的級別ID - >關鍵值[字符串，INT]

所以我做了

// Level ID -->[String][Progress] 
private Dictionary<int, KeyValuePair<string, int>> LevelProgress; 

我想添加一個關卡進度時，我只想有能力添加到當前進度，如果沒有進度，請添加一個新進度。問題是我無法添加到「當前」鍵值對任何新的整數。

public int AddProgress(int levelID, KeyValuePair<string, int> pair) 
    { 
     KeyValuePair<string, int> storedValue; 
     if (LevelProgress.TryGetValue(levelID, out storedValue)) 
     { 

     } 
     else 
     { 
      // add progress 
     } 
    }

從你的問題來看，我不太清楚你想要達到的目標。下面是一些你缺少一些類，闡明你的意圖測試，我想介紹你嘗試什麼......

[TestFixture] 
    class GameTests 
    { 

     [Test] 
     public void AddKeyValuePair() 
     { 
      var levelProgress = new Dictionary<int, KeyValuePair<string, int>>(); 
      KeyValuePair<string, int> storedValue; 
      if (levelProgress.TryGetValue(1, out storedValue)) 
      { 
       Assert.Fail("shouldn't get here"); 
      } 
      else 
      { 
       levelProgress[1] = new KeyValuePair<string, int>("something", 1); 
      } 

      Assert.IsTrue(levelProgress.ContainsKey(1)); 
      Assert.IsTrue(levelProgress[1].Equals(new KeyValuePair<string, int>("something", 1))); 
     } 

     [Test] 
     public void UpdateKeyValuePair() 
     { 
      var levelProgress = new Dictionary<int, KeyValuePair<string, int>> 
      { 
       {1, new KeyValuePair<string, int>("something", 1)} 
      }; 
      KeyValuePair<string, int> storedValue; 
      if (levelProgress.TryGetValue(1, out storedValue)) 
      { 
       //any operation 
       levelProgress[1] = new KeyValuePair<string, int>("newness", 100); 
      } 
      else 
      { 
       Assert.Fail("shouldn't get here"); 
      } 

      Assert.IsTrue(levelProgress.ContainsKey(1)); 
      Assert.IsTrue(levelProgress[1].Equals(new KeyValuePair<string, int>("something", 2))); 
     } 
    } 

但是，它真的感覺（和元組/ KeyValuePairs常提示本我） 。

例如這是一個猜測...

class Game 
{ 
    private Dictionary<int, LevelProgress> levelsProgress; 

    LevelProgress GetLevel(int i); 
} 

class LevelProgress 
{ 
    void AddProgress; 
}

定義Progress類2個屬性

public class Progress 
{ 
    private string sLabel = null; 
    public string Label 
    { 
     get { return this.sLabel; } 
     set { this.sLabel = value; } 
    } 

    private int iValue = -1; 
    public int Value 
    { 
     get { return this.iValue ; } 
     set { this.iValue = value; } 
    } 

    public Progress() 
    { 

    } 

    public Progress(string Label, int Value) 
    { 
     this.sLabel = Label; 
     this.iValue = Value; 
    } 
} 

你LevelProgress現在包含INT鍵和前進值

private Dictionary<int, Progress> LevelProgress; 

字典添加進度喜歡這個

public int AddProgress(int levelID, Progress P) 
{ 
    if(LevelProgress.ContainsKey(levelID)) 
    { 
     LevelProgress[levelID] = P; 
    } 
    else 
    { 
     LevelProgress.Add(levelID, P); 
    } 
}
