推荐答案

您的代码将在PictureBox控件中依次加载每个资源图像.但是，图片框控件一次只能显示一个图像.每次设置PictureBox.Image属性时，都将删除上一张图像，并用另一张图像替换.

如果需要同时显示多个图像，则可以使用Graphics.DrawImage在窗体上绘制它们，或者可以创建具有多个PictureBox控件的自定义控件.我建议您简单地在表单上绘制图像.

Your code would load each resource image sequentially in the PictureBox control. However, a picture box control can only display one image at a time. Each time you set the PictureBox.Image property, you''re removing the previous image and replacing it with another.

If you need to display multiple images simultaneously, you could instead draw them on your form using Graphics.DrawImage, or you could create a custom control with multiple PictureBox controls. I would suggest simply drawing the images on the form.
