推荐答案

这不行对我来说并不是很有帮助。



但是...猜测（因为你没有告诉我们你做了什么，你没有想到，或者你没有做到这一点，那就是我们所能做的全部），它会停止添加图像时它符合第一个非null。



所以你可能想要的是摆脱elseif部分：

"this is not working" is not exactly helpful.

But...at a guess (and since you don't tell us what it is doing that you didn't expect, or doing that you didn't, that's pretty much all we can do) it sill stop "adding images" when it meets the first non-null.

So what you probably want is to get rid of the elseif parts:

If picturebox1.image Is Nothing Then
   picturebox1.Image = System.Drawing.Image.FromFile("C:\image.Jpg")
EndIf
If picturebox2.image Is Nothing Then
   ...

依此类推。

如果所有六张图片都预先加载，它只会在当前进行更新。

And so forth.
It will only do the update at present if all six images are "loaded" in advance.
