c# - ListBox 插入颜色项目

Question

我使用 ListBox 来插入文本，例如 You add Michael in your database, You delete Michael, ...

 listBox1.Items.Insert(0,"You add " + name + " in your database\n");

它工作正常。我如何设置颜色一次为黑色(用于插入)一次为红色(用于删除)？我试过这个:

 public class MyListBoxItem
    {
        public MyListBoxItem(Color c, string m)
        {
            ItemColor = c;
            Message = m;
        }
        public Color ItemColor { get; set; }
        public string Message { get; set; }
    }

    private void listBox1_DrawItem(object sender, DrawItemEventArgs e)
    {
        MyListBoxItem item = listBox1.Items[e.Index] as MyListBoxItem; // Get the current item and cast it to MyListBoxItem

        if (item != null)
        {
            e.Graphics.DrawString( // Draw the appropriate text in the ListBox
            item.Message, // The message linked to the item
            listBox1.Font, // Take the font from the listbox
            new SolidBrush(item.ItemColor), // Set the color 
            0, // X pixel coordinate
            e.Index * listBox1.ItemHeight // Y pixel coordinate.  Multiply the index by the ItemHeight defined in the listbox.
            );
        }
        else
        {
            // The item isn't a MyListBoxItem, do something about it
        }
    }

在插入时:

 listBox1.Items.Insert(0, new MyListBoxItem(Color.Black, "You add " + name + " in your database\n"));
 listBox1.Items.Insert(0, new MyListBoxItem(Color.Red, "You delete " + name + "\n"));

此代码有效，但当我插入多个项目时，scrol 无法正常工作 - 文本不会出现。我究竟做错了什么？或者还有其他方法吗？

您是否考虑过在报 TableView 中使用 ListView 而不是列表框？这样您就不必为了获得颜色而自定义绘图。
