推荐答案

您可以通过设置 DrawMode 到 OwnerDrawFixed ，允许您使用 DrawItem 事件。

You can do this by setting the DrawMode to OwnerDrawFixed which allows you to manually draw the items using the DrawItem event.

comboBox1.DrawMode = DrawMode.OwnerDrawFixed;
comboBox1.DrawItem += new DrawItemEventHandler(comboBox1_DrawItem);

private void comboBox1_DrawItem(object sender, DrawItemEventArgs e) {    
    Font font = comboBox1.Font;
    Brush brush = Brushes.Black;
    string text = comboBox1.Items[e.Index]; 

    if (you want bold)
        font = new Font(font, FontStyle.Bold);

    if (you want green)
        brush = Brushes.Green;

    e.Graphics.DrawString(text, font, brush, e.Bounds);
}
