C# 给定一个简单的字典，构建一个嵌套的无序列表

给定一个字典，构建一个嵌套的html无序列表

我还发现了其他一些例子，其中有parentid等，但我并没有对数据的格式感到困惑。此外，如果某些“菜单”项有子项，它们的处理方式也会有所不同。我最初的想法是获得第一级计划表，即Performers，Home，然后通过一个包含所有元素的函数发送该列表

var dict2 = new Dictionary<string, string>() {
"Schedule|Friday","/Date/Classification?date=2020-03-06"

我想生成一个无序列表。 像这样

使用LinQ使其变得优雅，下面的代码块将实现拆分、分组和排序。它将把字典转换为匿名类型的分组集合

每个实例将有三个属性

LevelCount：字典条目键中的信息级别数

Levels:a | b | c作为字符串[]{a，b，c}的拆分版本

Url：字典条目的值，它是目标Url

---

这个代码块是用来打印集合的

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
        );
    });
});

打印出以下内容：

您可以更改打印输出逻辑以呈现HTML或任何您需要的内容

希望这能有所帮助。

不知何故，我认为递归可能会有所帮助，因为我们不知道有多少个级别（子级，然后是子级）。递归看起来像这样：查找“|”的索引，如果不是-1，则执行一些操作，然后再次调用方法本身，并更新新索引，以检查从该位置到字符串末尾的情况。

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
        );
    });
});
