C＃ - 我的列表中的项目不会显示 [英] C# - Items in my list wont show

问题描述

基本上我希望我的列表中的项目显示在控制台中...但我得到这个：



SimpleTextAdventure.Item

SimpleTextAdventure.Item

SimpleTextAdventure.Item





列表中有3项，所以我知道已添加的项目。但是不要把它们写成



剑

盾

火炬



已完成上述操作。为什么会这样？如果你想知道它是什么意思



SimpleTextAdventure是项目的名称，而.Item是其中一个类的名称。



请帮忙，我一整天都坚持这一点谢谢...

Basically I want the items in my list to show in the console... but instead i get this:

SimpleTextAdventure.Item
SimpleTextAdventure.Item
SimpleTextAdventure.Item


There are 3 items in the list, so i know the items have been added. But instead of writing them out like

Sword
Shield
Torch

Is has done the above instead. Why is this happening? If your wondering what it means

SimpleTextAdventure is the name of the project, and .Item is the name of one of the classes.

Please help, ive been stuck on this all day long thanks...

推荐答案

无法正确理解您的查询但是我理解您需要在控制台上显示列表项。如果您的课程如下：

Not able to understand your query properly but as i am understanding you need to display list item on console .If your class like below :

class Items
    {
        List<string> lst = new List<string>();
        

       
        public IList GetList()
        {
            lst.Add("Sword");
            lst.Add("Shield");
            lst.Add("Torch");
            return lst;
        }

    }

然后您可以使用以下代码显示列表值：

then you can display list value by using such code :

static void Main(string[] args)
        {

            Items _items = new Items();
            IList lst = _items.GetList();

            foreach(string l in lst)
            {
                Console.WriteLine(l);
              
            }
            Console.ReadKey();
          }

与之前的其他问题（几乎相同的代码）一样，它是同一类型的问题。你绑定了对象Item（名称的选择不好）而不是Item的ItemName属性。



你需要像这样更改PrintItems。

Like the other question earlier (almost Identical code) it is the same type of problem. You are binding the object Item (poor choice for a name) and not the ItemName property of the Item.

you NEED to change the PrintItems like this.

public static void PrintItems()
{
    foreach (Item itemName in _inventory)
    {
        Console.WriteLine(itemName.ItemName);
    }
}

我解决了这些家伙：）...基本上，它是愚蠢的东西....我基本上不得不把一个字母从大写改为小写...





而不是... itemName ...我有它的ItemName。 ...

I solved it guys :)... basically, it was something soo stupid.... I basically had to change a letter from uppercase to lowercase...


Instead of ...itemName... i had it ItemName....

public static void PrintItems()
        {
            foreach (Item itemName in _inventory)
            {
                Console.WriteLine(itemName.itemName);
            }
        }

public Item(string itemName)
{
    _itemName = itemName;
}

// Properties
public string itemName { get { return _itemName; } }
