图片框C#的随机输出图像 [英] Random out image for picture box c#

问题描述

我正在一个装有此图片框的Winform上工作.我有52张不同的图像，并且在此特定的图片框中将仅显示1张图像.我不确定在不以52 if语句结束的情况下应该如何做.任何人都可以帮我解决这个问题，因为我在编程方面还是个新手:)

I'm working on a Winform where I have this picture box. I have 52 different images and only 1 image is going to be shown in this particular picture box. I'm not really sure how I should do this without ending up with 52 if statements. Could anyone help me with this as I'm still kinda new in programming :)

我正在用C#编程

谢谢！ :D

推荐答案

第一步是列出某种形式的列表，以存储所有图像.您可以选择图像列表或它们的路径列表.

The first step would be to make a list of some sort to store all your images. You can either opt for a list of Images, or a list of their paths.

如果使用图像路线，则可以使用List<Image> images = new List<Image>();创建图像列表，并为每个image使用images.Add(image);将每个图像添加到图像列表中.

If you're using the Image route, you can create a list of images with List<Image> images = new List<Image>(); and add each image to it with images.Add(image); for each image.

如果使用路径路由，则可以使用List<String> paths = new List<String>();创建路径列表，并使用paths.Add(path);为每个path添加每个图像.

If you're using the path route, you can create a list of paths with List<String> paths = new List<String>(); and add each image to it with paths.Add(path); for each path.

然后，当您将图片框设置为随机图像时，您可以生成一个随机数并从列表中选择一个.

Then, when you're setting the picture box to a random image, you can generate a random number and pick one out of the list.

对于图像:

Random random = new Random();
pictureBox1.Image = images[random.Next(0, images.Count - 1)];

对于路径:

Random random = new Random();
pictureBox1.ImageLocation = paths[random.Next(0, images.Count - 1)];

正如Tuukka所说，使用路径是一个更好的主意(从内存使用的角度来看)，除非您是动态创建图像的，或者由于其他原因已经拥有了图像.

As Tuukka says, using paths is a much better idea (memory usage-wise), unless you've created the images dynamically, or already have the images for some other reason.
