c# - 如何返回 ListView 项目的集合？

Question

很抱歉关于 ListViewItems 的新手问题，但之前从未使用过 ListView，我想做的是从中返回所有 ListViewItems AnimalManager 类回到 UI lsbOverview 控件。采用这种方法的原因是我有一个 Manager 类来处理所有数据并将其返回给 UI 控件。问题是如何将所有项目返回到 lsboverView ListView？

    // declared in AnimalManager class
    private static List<Animal> AnimalList { get; set; }


     public static ListViewItem DisplayAllAnimals()
    {
        //Show animals on ListView by proper column
        foreach (var animal in AnimalList)
        {
            ListViewItem item = new ListViewItem(animal.Id); // generated ID
            item.SubItems.Add(animal.AnimalSort); // AnimalSort
            item.SubItems.Add(animal.Name); //Name
            item.SubItems.Add(animal.Age); //Age
            item.SubItems.Add(animal.Gender.ToString()); // Animal gender

            return item;
        }

        // how to return all items back to UI ?
    }


    // Mainform UI class where its used
    lsbOverview.Items.Add(AnimalManager.DisplayAllAnimals());

你在找这个吗？

// declared in AnimalManager class
    private static List<Animal> AnimalList { get; set; }


     public static ListViewItem[] DisplayAllAnimals()
    {
        //Show animals on ListView by proper column
        var listViewItems = new List<ListViewItem>();
        foreach (var animal in AnimalList)
        {
            ListViewItem item = new ListViewItem(animal.Id); // generated ID
            item.SubItems.Add(animal.AnimalSort); // AnimalSort
            item.SubItems.Add(animal.Name); //Name
            item.SubItems.Add(animal.Age); //Age
            item.SubItems.Add(animal.Gender.ToString()); // Animal gender
            listViewItems.Add(item);

        }

        return listViewItems.ToArray();
    }


    // Mainform UI class where its used
    lsbOverview.Items.AddRange(AnimalManager.DisplayAllAnimals());
