我想知道如果菜单上选择了一个选项，如果不不断创建一个新列表，该如何将链接列表与菜单系统保持在一起？并且还想知道是否可以像在下面突出显示的图像的普通列表中一样，向列表中添加多个“恐龙”？enter image description here

在该方法之外创建对列表的静态引用：
public static LinkedList Nodes = new LinkedList();
然后在需要时像Nodes.AddAtLast(xxx)一样访问它。
关于您的其他问题，是的，您可以在列表中添加更多元素。但是列表（在您的img中）和链接列表（在您的代码中）之间有明显的区别。您似乎在一个不典型的列表中添加了有关单个恐龙的多个详细信息。您通常希望创建一个Dinosaur类，该类具有一些属性，例如您当前保存为单个节点的属性。
