推荐答案

此 [使用 [

This[^] might help you out.

You will need to write some code to use[^] Random() and populate random images.

 public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        FileInfo[] fileInfo;
        List<image> imgList;

        private void Form1_Load(object sender, EventArgs e)
        {
            DirectoryInfo drInfo = new DirectoryInfo("Images");
            fileInfo = drInfo.GetFiles("*.jpg");
            imgList = new List<image>();

            foreach (var item in fileInfo)
            {
                imgList.Add(Image.FromFile(item.FullName));
            }

        }
        Random rnd = new Random();
        private Image RandomPicButton()
        {
            int rndNumber = rnd.Next(imgList.Count);
            return imgList[rndNumber];
        }

        private void randomCLick(object sender, EventArgs e)
        {
            button9.Image = RandomPicButton();
            button10.Image = RandomPicButton();
            button13.Image = RandomPicButton();
            button14.Image = RandomPicButton();
        }
    }
</image></image>

这项工作.所有按钮都可拥有一个事件.
如果将Random放入RandomPicButton()会返回相同的图片，则很有趣.
我正在学习C#，因此欢迎对我的代码进行注释

This Work. One Event to All buttons.
It is interesting if Random put inside RandomPicButton() it return the same picture.
I learning C#, so comments about my code are welcomed
