图像在c# winforms中单击选择下拉项

// 创建一个下拉列表控件
ComboBox comboBox = new ComboBox();
comboBox.Location = new Point(10, 10);
comboBox.Width = 200;

// 添加图像项
ImageList imageList = new ImageList();
imageList.Images.Add(Properties.Resources.Image1); // 添加图像1
imageList.Images.Add(Properties.Resources.Image2); // 添加图像2
comboBox.DrawMode = DrawMode.OwnerDrawFixed;
comboBox.DrawItem += (sender, e) =>
{
    if (e.Index >= 0)
    {
        // 绘制图像
        e.Graphics.DrawImage(imageList.Images[e.Index], e.Bounds.Left, e.Bounds.Top, e.Bounds.Height, e.Bounds.Height);
        
        // 绘制文本
        e.Graphics.DrawString(comboBox.Items[e.Index].ToString(), comboBox.Font, Brushes.Black, e.Bounds.Left + e.Bounds.Height, e.Bounds.Top);
    }
};

// 添加下拉项
comboBox.Items.Add("Item 1");
comboBox.Items.Add("Item 2");

// 将下拉列表控件添加到窗体中
this.Controls.Add(comboBox);
