C# 防止在 class 之外设置字典属性元素？

Question

标题说明了一切。通过访问修饰符减少访问只会阻止重新初始化属性;它不会阻止元素成为全局状态（不良做法）。我知道有一个 workaround with List<T>'s 但我应该为任何其他索引 collection 做什么？

public class Start
{
    public static void main()
    {
        //CODE SMELL AHEAD
        AttendanceManager.MuteStatuses[0] = new KeyValuePair <string, string> ("", ""); 
    }
}

public static class AttendanceManager
{ 
    public static HybridDictionary MuteStatuses
    {
        get
        {
            playersMuteStatuses.Add ("", "");
            return playersMuteStatus;
        }
    }      
    private static HybridDictionary playersMuteStatus = new HybridDictionary();
}

Answer 1

编写辅助方法：

public static void AddMuteStatus()
    => playersMuteStatus.Add("", "");

public static object GetMuteStatus(object idx)
    => return playersMuteStatus[idx];

Answer 2

不要使用 HybridDictionary。我们有 IReadOnlyDictionary<T>

private Dictionary<string, string> playersMuteStatus = new... ;
public IReadOnlyDictionary<string, string> MuteStatuses
{
    get
    {
        return playersMuteStatus as IReadOnlyDictionary<string, string>;
    }
}
