盒子要在里面对齐。例如，如果我的预计数等于4，那么它将在groupbox中动态创建PictureBox。它所做的只是居中/填充分组框。其他的图片框看不见。你能给出一个参考我上面代码的示例代码吗？因为它太复杂了。我不明白为什么我的pictureboxes只停留在一个位置。@LyndonBrozTonelete:我添加了一些代码，还对您的代码添加了一些注释。我想知道是否可以在我的每个PictureBox下面放置dynamic radiobutton。。也有可能吗？@LyndonBrozTonelete:RadioButton控件有一个

Image

属性，您可以使用它来代替图片框。

CheckAlign

和

ImageAlign

属性使您可以控制布局。
