Question

从JSON加载的数组中对字段进行排序的最简单方法是什么。我在匿名函数中找到了一些东西，但我想知道这是否是一种更基本的方法。

 static void SortItems(Items[] items)
    {

        Console.WriteLine("Choose field to sort (Name, Weapon, Strength)");
        string userInput = Console.ReadLine();
        Items[] sortedItem;
        if (userInput.ToLower() == "name")
        {
            string[] name = items.Select( m => m.Name).ToArray();    

        }

        else if (userInput.ToLower() ==  "weapon")
        {
            string[] weapon = items.Select(m => m.EquippedWeapon.Name).ToArray();

        }
        else if (userInput.ToLower() == "strength")
        {
            int[] totalStrength = items.Select(m => m.GetStrength()).ToArray();
        }

         sortedItems = Sorts.Sort(items, userInput);

        foreach (Items c in sortedItems)
        {
            Console.WriteLine("Name : {0} - Weapon: {1} - Total strength: {2}", c.Name, c.Weapon.Name,  c.strength().ToString());
        }

    }

如果你能够使用Linq扩展，你可以做更像这样的事情

static void SortItems(Items[] items)
{

    Console.WriteLine("Choose field to sort (Name, Weapon, Strength)");
    string userInput = Console.ReadLine();
    if (!string.IsNullOrWhiteSpace(userInput))
    {
        Items[] sortedItems;
        switch (userInput.Trim().ToLower())
        {
            case ("name"):
                sortedItems = items.OrderBy(x => x.Name).ToArray();
                break;
            case ("weapon"):
                sortedItems = items.OrderBy(x => x.Weapon).ToArray();
                break;
            case ("strength"):
                sortedItems = items.OrderBy(x => x.Strength).ToArray();
                break;
            default:
                //return whatever for default
                sortedItems = items.OrderBy(x => x.Name).ToArray();
                break;
        }

        foreach (Items c in sortedItems)
        {
            Console.WriteLine("Name : {0} - Weapon: {1} - Total strength: {2}", c.Name, c.Weapon.Name,
                c.strength().ToString());
        }
    }
