链接列表是否未使用正确的元素打印？

Question

我想知道如何打印出链接列表，因为它当前用我编写的代码显示错误的文本？

Dinosaur Dino1 = new Dinosaur();                           
Console.WriteLine("You have selected Create a New Dinosaur");
Console.WriteLine("Please enter Dinosaur ID ");
Dino1.ID = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("Please enter Dinosaur Species");
Dino1.Name = Console.ReadLine();
Console.WriteLine("Please enter Dinosaur Diet Type");
Dino1.Type = Console.ReadLine();
Console.WriteLine("Please enter Dinosaur Period");
Dino1.Period = Console.ReadLine();
Dinolist.AddFirst(Dino1);
foreach (Dinosaur str in Dinolist)
{
    Console.WriteLine(str); 
}

这是显示的内容：
