How To sort Dictionary After Adding data to it (C#)-CodePudding

Hello Everyone my problem is when i add the data to Dictionary in c# and i want to switch (Sortype) string to check how the user wants the order data like this:

string Sortype ="ByDate";
Dictionary<string, Data> MyDictionary = JsonConvert.DeserializeObject<Dictionary<string, Data>>(Res.Body.ToString());
                           switch (Sortype)
                            {
                                case "ByViews":
                                    WorldInfo.OrderByDescending(AllData => AllData.Value.WorldPDownloads).ToList();
                                    break;
                                case "ByDownloads":
                                    WorldInfo.OrderBy(AllData => AllData.Value.WorldPDownloads).ToList();
                                    break;
}

In this way, the code Will Not work and the Data does not sorted but when i use this way the code will work but i cant switch (Sortype) because also the code will not work when i switch (SortData) Variable:

                    Dictionary<string, Data> MyDictionary = JsonConvert.DeserializeObject<Dictionary<string, Data>>(Res.Body.ToString());
                    var SortData = MyDictionary.OrderByDescending(x => x.Value.ByViews).ToList();

So I'm looking for the right way to do it. Thank you :)

The reason it does not work in your case is because OrderByDescending returns an object after ordering.

You can do something like this

        Dictionary<string, Data> MyDictionary = JsonConvert.DeserializeObject<Dictionary<string, Data>>(Res.Body.ToString()));
        var data = Sortype == "ByViews" ? WorldInfo.OrderByDescending(AllData => AllData.Value.WorldPDownloads).ToList() : Sortype == 'ByDownloads' ? WorldInfo.OrderBy(AllData => AllData.Value.WorldPDownloads).ToList() : null;

        string Sortype = "ByDate";
        Dictionary<string, Data> MyDictionary = JsonConvert.DeserializeObject<Dictionary<string, Data>>(Res.Body.ToString());
        switch (Sortype)
        {
            case "ByViews":
                WorldInfo = WorldInfo.OrderByDescending(AllData => AllData.Value.WorldPDownloads).ToList();
                break;
            case "ByDownloads":
                WorldInfo =WorldInfo.OrderBy(AllData => AllData.Value.WorldPDownloads).ToList();
                break;
        }

I do not know if that is a bug or just missing on purpose but you are setting string Sortype ="ByDate"; without actually having a "ByDate" in the switch statement.
