I am trying to list each pet in the pet class on my form for my C# .NET project.

Question

I am trying to list each pet in the pet class on my form for my C# .NET project. I am getting an error that says pet is a type which is not valid in the given contex.

This is the peice of code causing the error:

foreach (var item in Pet)
{
Console.WriteLine("list item " + item.arrivalDate );
petList.Text = "list item " + item.arrivalDate;

}

Pet is the super class -> cat and dog inherit from pet -> chiwawa and husky inherit from dog/ siamese and tabby inherit from cat

This line of code shows that I have 4 in the pet class: petCount.Text = "Pets Available : " + Pet.petCount;

Not sure how else besides a for loop I would be able to show the arrival date of each pet?

Here is my form:

______________________________________________________

namespace FinalProject
{
public partial class Form1 : Form
{
public Form1()
{
  
InitializeComponent();
  

}

private void Form1_Load(object sender, EventArgs e)
{
Tabby sunshine = new Tabby(22222222222222222, new DateTime(2016, 2, 24), false);

Chiwawa tony = new Chiwawa(33333333333333333, new DateTime(2016, 2, 24), false);

Siamese felix = new Siamese(44444444444444444, new DateTime(2016, 3, 11), false);

Husky fluffs = new Husky(55555555555555555, new DateTime(2016, 2, 24), false);
  
foreach (var item in Pet)
{
Console.WriteLine("list item " + item.arrivalDate );
petList.Text = "list item " + item.arrivalDate;

}
  
petCount.Text = "Pets Available : " + Pet.petCount;
  
}
}
}

Explanation / Answer

Foreach statement executes a single statement or multiple statement for evey element in an instance of type that implements collection.

Here you are using:

foreach (var item in Pet)

this is a Pet class not collecction

You hav to use something like this

foreach (var item in PetList)

where PetList has to be a instance of the list class or collection.
