如何着色ListBox项目？

Question

我想改变一个ListBox 项目的颜色.我的代码似乎不起作用.它只是将类的名称空间添加到ListBox项目中.

class myListboxItem
{
    public Color ItemColor { get; set; }
    public string Message { get; set; }

    public myListboxItem(Color c, string m)
    {
        ItemColor = c;
        Message = m;
    }
}

将项添加到的代码ListBox:

listBox1.Items.Add(new myListboxItem(Color.Red,"SKIPPED: " + partThreeOfPath));

这会ListBox在黑色中添加一个项目AddFoldersToClientFolder.myListboxItem.

您可以使用DrawItemListBox的事件:

private void listBox1_DrawItem(object sender, DrawItemEventArgs e)
{
    var item = (myListboxItem)listBox1.Items[e.Index];
    e.DrawBackground();

    using (var brush = new SolidBrush(item.ItemColor))
        e.Graphics.DrawString(item.Message, listBox1.Font, brush, e.Bounds);
}

注意:您还需要将DrawModeListBox 设置为DrawMode.OwnerDrawFixed或DrawMode.OwnerDrawVariable
