Учитывая простой словарь, построить вложенный неупорядоченный список

Question

Учитывая, что Словарь строит вложенный html неупорядоченный список.

Я нашел другие примеры, где есть parentid et c, но я не обхожу голову вокруг формата данных. Кроме того, некоторые пункты меню обрабатываются по-разному, если они имеют подпункты. Сначала я хотел получить первый уровень, а именно Schedule, Performers, Home, а затем отправить этот список через функцию со всеми элементами, имеющими

var dict2 = new Dictionary<string, string>() {
"Schedule|Friday","/Date/Classification?date=2020-03-06"
"Schedule|Saturday","/Date/Classification?date=2020-03-07"
"Schedule|Sunday","/Date/Classification?date=2020-03-08"
"Schedule|Regional","/Schedule/Classification?classification=Regional"
"Schedule|Culinary","/Schedule/Classification?classification=Culinary"
"Schedule|Storytellers","/Schedule/Classification?classification=Storytellers"
"Schedule|National","/Schedule/Classification?classification=National"
"Schedule|Urchin Street","/Schedule/Classification?classification=Urchin%20Street"
"Schedule|Horses and Sheep","/Schedule/Classification?classification=Horses%20and%20Sheep"
"Schedule|Dance","/Schedule/Classification?classification=Dance"
"Performers|Regional|SomeMenuText0","/Performers/Index/b905cf6f-6c63-4b48-9988-10eba9799c23"
"Performers|Regional|SomeMenuText1","/Performers/Index/f9de249a-5026-4d1f-803c-1cf1574fdb9c"
"Performers|Culinary|SomeMenuText2","/Performers/Index/9724e1a5-48b2-46ee-a3cd-8878eb4c4f45"
"Performers|Culinary|SomeMenuText3","/Performers/Index/6efbe6ae-fd01-4895-9a25-74722053f7e1"
"Performers|Regional|SomeMenuText4","/Performers/Index/bbcff599-7ec7-4cbe-911b-27c8bf2cc6fc"
"Performers|Storytellers|SomeMenuText5","/Performers/Index/4ada12f6-06e7-4112-9f7a-73d028777c29"
"Performers|National|SomeMenuText6","/Performers/Index/9650749d-de27-4c6f-8804-7c3b70eae78a"
"Performers|Urchin Street|SomeMenuText7","/Performers/Index/a5197e3e-60cc-4076-b1be-4d14d6c4455e"
"Performers|Urchin Street|SomeMenuText8","/Performers/Index/aa9f52dd-0fe2-4450-bc0e-5e756e2ff236"
"Performers|Culinary|SomeMenuText9","/Performers/Index/6e572975-5f8c-494a-9906-546d54c96671"
"Home","/Home/ViewContent/051ec1ce-386b-4070-957a-7515331b7bff"
}

. Я хотел бы создать неупорядоченный список. вот так

 <ul class="nav navbar-nav mr-auto">
    <li class="nav-item"><a href="/Home/ViewContent/051ec1ce-386b-4070-957a-7515331b7bff">Home</a></li>

Answer 1

Используя LinQ, чтобы сделать его элегантным, следующий блок кода будет выполнять разбиение, группирование и сортировку. Он преобразует словарь в сгруппированную коллекцию анонимных типов.

Каждый экземпляр будет иметь три свойства:

1. LevelCount: количество информационных уровней в ключе ввода словаря
2. Уровни: разделенная версия a | b | c в виде строки [] {a, b, c}
3. Url: значение словарной записи, которая является целевым URL

---

var groupedList = dict2
    .Select((x) => new { Levels = x.Key.Split('|'), LevelCount = x.Key.Split('|').Length, Url = x.Value })
    .OrderBy((x) => x.LevelCount)
    .OrderBy((x) => x.LevelCount > 1 ? x.Levels[1] : x.Levels[0])
    .GroupBy((x) => x.LevelCount)
    .ToList();

А этот блок кода предназначен для распечатки коллекции.

groupedList.ForEach((x) =>
{
    x.ToList().ForEach((y) =>
    {
        Console.WriteLine
        (
            y.LevelCount > 2 ? (y.Levels[1] + " / " + y.Levels[0] + " [Text=" + y.Levels[2] + "] => " + y.Url) :
            y.LevelCount > 1 ? (y.Levels[0] + " of " + y.Levels[1] + " => " + y.Url) :
            y.Levels[0] + " => " + y.Url
        );
    });
});

, которая печатает следующее:

Schedule of Culinary => /Schedule/Classification?classification=Culinary
Schedule of Dance => /Schedule/Classification?classification=Dance
Schedule of Friday => /Date/Classification?date=2020-03-06
Schedule of Horses and Sheep => /Schedule/Classification?classification=Horses%20and%20Sheep
Schedule of National => /Schedule/Classification?classification=National
Schedule of Regional => /Schedule/Classification?classification=Regional
Schedule of Saturday => /Date/Classification?date=2020-03-07
Schedule of Storytellers => /Schedule/Classification?classification=Storytellers
Schedule of Sunday => /Date/Classification?date=2020-03-08
Schedule of Urchin Street => /Schedule/Classification?classification=Urchin%20Street
Culinary / Performers [Text=SomeMenuText2] => /Performers/Index/9724e1a5-48b2-46ee-a3cd-8878eb4c4f45
Culinary / Performers [Text=SomeMenuText3] => /Performers/Index/6efbe6ae-fd01-4895-9a25-74722053f7e1
Culinary / Performers [Text=SomeMenuText9] => /Performers/Index/6e572975-5f8c-494a-9906-546d54c96671
National / Performers [Text=SomeMenuText6] => /Performers/Index/9650749d-de27-4c6f-8804-7c3b70eae78a

Regional / Performers [Text=SomeMenuText4] => /Performers/Index/bbcff599-7ec7-4cbe-911b-27c8bf2cc6fc
Storytellers / Performers [Text=SomeMenuText5] => /Performers/Index/4ada12f6-06e7-4112-9f7a-73d028777c29
Urchin Street / Performers [Text=SomeMenuText7] => /Performers/Index/a5197e3e-60cc-4076-b1be-4d14d6c4455e
Urchin Street / Performers [Text=SomeMenuText8] => /Performers/Index/aa9f52dd-0fe2-4450-bc0e-5e756e2ff236
Home => /Home/ViewContent/051ec1ce-386b-4070-957a-7515331b7bff

You можете изменить логи распечатки c для рендеринга HTML или того, что вам нужно.

Надеюсь, это поможет.
