Effective way of storing user input data that contains a string and int, List or Array? C#

For a personal project I want to make a simple Inventory system in C#. There are three inputs, itemName(string), itemQuantity(int), itemLevelAlert(int), and then a button.

When the 'Add' button is clicked, I want the input data to be grouped and stored somewhere. I am not experienced in C# enough to know the best way to do this.

In JavaScript I'd probably use a multi-dimension array:

var inventoryArray = [["Hammer", 25, 5], ["Nails", 100, 20]]

and simply push the input to that array. I'm still learning C# and it goes about arrays a bit differently.

Could I do something similar with a list? I'm probably jumping into deep here considering my inexperience but I feel like I learn better that way.

You can use string and int types doing the following:

            (string, int, int)[] Cats = 
            { 
                ("Tom", 20, 3), ("Fluffy", 30, 4), ("Harry", 40, 5), ("Fur Ball", 40, 6) 
            };
            
            foreach (var cat in Cats)
            {
                Console.WriteLine($"My cats name is {cat.Item1} it is {cat.Item2} years old and weights {cat.Item3} lbs.");
            }

You can start with defining your model :

internal class Inventory
    {
        public string ItemName { get; set; }

        public int ItemQuantity { get; set; }

        public int ItemLevelAlert { get; set; }
    }

Then, you should declare list of inventory where you will store your newly created inventory :

var inventoryList = new List<Inventory>();

After that, you need to add your inventory in above inventoryList in button click event :

button.Click += (s, e) =>
            {
                inventoryList.Add(new Inventory()
                {
                    // get value from your form
                    ItemName = "Item1",
                    ItemLevelAlert = 1,
                    ItemQuantity = 5
                });

In .Net languages like C#, you typically want to build a type (class) for this kind of thing:

public class Item
{
   public string Name {get;set;}
   public int Quantity {get;set;}
   public int AlertLevel {get;set;}
}

And then you create a generic List object that can hold these items (and only these items!)

var inventory = new List<Item>();

And now, when you click add, the code for the button looks something like this (assuming Winforms and with lots of made-up variable names. Web sites will look different):

//assuming Winforms. Code for a web site will look a bit different:
private void button1_Click(object sender, EventArgs e)
{
    int quantity, alertlevel;
    if (!int.TryParse(txtQuantity.Text, out quantity))
    {
       MessageBox.Show("Enter a valid number for the quantity.");
       return;
    }
    if (!int.TryParse(txtQuantity.Text, out alertlevel))
    {
       MessageBox.Show("Enter a valid number for the alert level.");
       return;
    }

    inventory.Add(new Item() {Name = txtName.Text, Quantity = quantity, AlertLevel = alertlevel});
}
