推荐答案

这很难精确，因为您对应用程序的了解不多，以及如何存储图像，但假设它们位于文件夹中:

It''s difficult to be precise, wtihout knowing more about your application, and how you store your images, but assuming they are in a folder:

private Random rand = new Random();
private Image GetRandomImage( string myImageFolderPath )
    {
    string[] files = Directory.GetFiles(myImageFolderPath);
    int i = rand.Next(files.Length);
    return Image.FromFile(files[i]);
    }

相应地命名您的图片(以image_1，image_2，image_3等结尾).然后使用随机对象将URL更改为ImageUrl:

Hi,
Name your pictures accordingly (ending with image_1, image_2, image_3, etc.). Then change the URL to the ImageUrl with a random object:

Random rand = new Random();
pictureBox.ImageUrl = "Your URL" + "\\image_" + rand.Next(1,6);

亲切的问候
