get a value from data (not list or dictionary)

Question

Sorry im newb and I don't know how to ask my question properly in the title. I have a database:

class PlayerData
    {
        public ulong id;
        public string name;
        public int kills;
        public int deaths;
    }

and I want to return the value corresponding to the requested key

object getStats(ulong uid, string stat)
    {
        var player = BasePlayer.FindByID(uid);
        PlayerData data = PlayerData.Find(player);

        object value = data.TryGetValue(stat); // I know this ain't right

        return value;
    }

example:

int kills = getStats(123456, kills); //will ask for the value of "kills" in the data. Return data.kills

stat could be anything in data (id, name, kills, deaths)

thanks alot!

How about using switch. For example object TryGetValue(string stat) { object returnValue=null; switch(stat) { case "name": returnValue=name; break; case "kills": returnValue=kill; break; } return returnValue; } — Sun Maung Oo, Jun 07 '18 at 23:16

You could take Sun Maung Oo's suggestion of using a switch statement:

object TryGetValue(int playerId, string name)
{
    var player = GetPlayer(playerId);
    switch (name)
    {
        case "name": return name;
        case "kills": return kills;

        // Other properties
        // ...

        default: return null;
    }
}

Or you could flatten the data:

public class Statistic
{
    public int PlayerId { get; set; }
    public string Name { get; set; }
    public object Value { get; set; }
}

Then finding the value is a matter of finding the statistic with the given player id and name.

I suppose what you are trying to do here is to get the object value base on the object Name? If that is the case, I think you could use reflection to achieve that. You could reference this answer: Get property value from string using reflection in C#

Sample Code:

class PlayerData
{
    public ulong id;
    public string name;
    public int kills;
    public int deaths;
}

object getStats(ulong uid, string stat)
{
    var player = BasePlayer.FindByID(uid);
    PlayerData data = PlayerData.Find(player);

    object value = data.GetType().GetProperty(stat).GetValue(data, null);

    return value;
}
