如何创建和使用作为 class 实例的项目列表

Question

I'm looking for a simple way to store and access Iteminfo .

I have a Database with a Table with the following data: ItemId , uItemname , Itemname , ItemDesc , ItemSize ; usually 20 records but can be more.
The problem is I don't know how to create a structure that supports multiple Items that can easily be read.

What I am looking for is a structure that can create Items that are easily read and can be created within the code.

Example:

public class Item
{
     public int ItemId {get; set;}
     public string uItemname {get; set;}
     public string Itemname {get; set;}
     public string ItemDesc {get; set;}
     public float ItemSize {get; set;}
} 

And inside the code I want to make a new one like

Item.Add(0,"test_item","Test","TestDesc",22.5f);

And when I ask something I need a way to access it like:

foreach(Item i in Item//IDk how to access all Created)
{
  if(i.Itemname == "Test")
  {
     print(i.uItemname +"|"+ i.ItemSize);
  }
}

Check out generic collections like the List .

You can add items easily like this

var listOfItems = new List<Item>();
var yourNewItem = new Item {
    ItemId = 0,
    uItemname = "test_item",
    Itemname = "Test",
    ItemDesc = "TestDesc",
    ItemSize = 22.5f
};

listOfItems.Add(yourNewItem);

And iterating through the list is done via foreach

foreach (Item i in listOfItems) {
  if(i.Itemname == "Test")
    print(i.uItemname +"|"+ i.ItemSize);
}
