Question

    public void saveSettings()
    {
        refreshSettings();
        userSettings.sword = swordEquiped;
        userSettings.staff = staffEquiped;
        userSettings.bow = bowEquiped;
        userSettings.overalldamage = overallDamage;
        userSettings.silver = silver;
        userSettings.gold = gold;
        userSettings.exp = exp;
        userSettings.level = level;
        userSettings.physical = physicalDamage;
        userSettings.magic = magicDamage;
        userSettings.ranged = rangedDamage;
        userSettings.inventory = string.Join(", ", itemsBought.ToArray());
        userSettings.Save();
    }
    public void loadSettings()
    {
        exp = userSettings.exp;
        level = userSettings.level;
        swordEquiped = userSettings.sword;
        staffEquiped = userSettings.staff;
        bowEquiped = userSettings.bow;
        overallDamage = userSettings.overalldamage;
        silver = userSettings.silver;
        gold = userSettings.gold;
        physicalDamage = userSettings.physical;
        magicDamage = userSettings.magic;
        rangedDamage = userSettings.ranged;
        nameChosen = userSettings.username;
        itemsBought = userSettings.inventory;
    }

我有一个名为List<string>的{{1}}，它有3个值，只是项目名称itemsBought。我想知道如何将列表添加到字符串中，因为这有效：

"Short Sword", "Shortbow", "Staff of Energy"

但是当我尝试加载它时：

userSettings.inventory = string.Join(", ", itemsBought.ToArray());

它无法转换它，给我一个错误itemsBought = userSettings.inventory;。

Answer 1

首先，将您的连接字符串更改为","（无空格），然后尝试：

itemsBought = userSettings.inventory.Split(',').ToList();

或者也许这个（也许你有一些从InventoryItem类到类型string的隐式转换，所以需要重新创建那些）：

itemsBought = userSettings.inventory
   .Split(',')
   .Select(s => new InventoryItem(s))
   .ToList();

Answer 2

您需要使用string.Split（）

将其转换回数组

using System;

public class SplitTest {
    public static void Main() {

        string words = "This is a list of words, with: a bit of punctuation" +
                       "\tand a tab character.";

        string [] split = words.Split(new Char [] {' ', ',', '.', ':', '\t' });

        foreach (string s in split) {

            if (s.Trim() != "")
                Console.WriteLine(s);
        }
    }
}
// The example displays the following output to the console: 
//       This 
//       is 
//       a 
//       list 
//       of 
//       words 
//       with 
//       a 
//       bit 
//       of 
//       punctuation 
//       and 
//       a 
//       tab 
//       character

无法将字符串转换为列表错误
