推荐答案

private void listBox1_DrawItem(object sender, DrawItemEventArgs e)
{
    if (e.Index<0) return;
    //if the item state is selected them change the back color 
    if ((e.State & DrawItemState.Selected) == DrawItemState.Selected)
        e = new DrawItemEventArgs(e.Graphics, 
                                  e.Font, 
                                  e.Bounds, 
                                  e.Index,
                                  e.State ^ DrawItemState.Selected,
                                  e.ForeColor, 
                                  Color.Yellow);//Choose the color

    // Draw the background of the ListBox control for each item.
    e.DrawBackground();
    // Draw the current item text
    e.Graphics.DrawString(listBox1.Items[e.Index].ToString(),e.Font, Brushes.Black, e.Bounds, StringFormat.GenericDefault);
    // If the ListBox has focus, draw a focus rectangle around the selected item.
    e.DrawFocusRectangle();
}

使用逻辑以上。

use above logic.

如果没有，你就不能这样做将 DrawMode 属性更改为

You can't do that without changing the DrawMode Property to

DrawMode.OwnerDrawFixed<br />

但这将删除一些功能，然后您必须添加所有项目都由您自己编程。

这里我用Google搜索了一个C＃样本;

在C＃中创建一个自己绘制的ListBox - C＃HelperC＃Helper



我有在VB.NET中制作了这样一个ComboBox控件，具有许多扩展功能，如： BorderColor，DisplayText，ItemsForeColor，ItemsBackColor，ItemsFont等..

如果你想要它我可以发送到你的电子邮件，它是在VB.NET。



如果有帮助，请接受这个答案。

but that will remove some functionality, you then have to add all items programatically by your own.
Here i googled a C# sample;
Make an owner-drawn ListBox in C# - C# HelperC# Helper

I have made such a ComboBox control in VB.NET with many extended features like; BorderColor, DisplayText, ItemsForeColor, ItemsBackColor, ItemsFont etc..
If you want it i can send it to your Email, it's in VB.NET.

Please accept this answer if it helped you.
