You just need to subscribe to MouseHover Event an change Image Property.

您只需要订阅MouseHover事件即可更改图像属性。

This should do the trick:

这应该是诀窍：

PictureBox o = new PictureBox();
o.MouseHover += (a_sender, a_args) =>
{
    PictureBox pic = a_sender as PicureBox;
    pic.Image = null // New Image..
};

Again when you need to restore previous picture use: MouseLeave

再次当您需要恢复上一张图片时：MouseLeave

On PictureBox properties, double click on event MouseEnter and use:

在PictureBox属性上，双击事件MouseEnter并使用：

(sender as PictureBox).Image = Image.FromFile(// path of image1);

then double click on event MouseLeave and use:

然后双击事件MouseLeave并使用：

(sender as PictureBox).Image = Image.FromFile(// path of image2);
