如何获得来自ImageLocation的图片框图像的宽度和高度？

I'm trying to expand my form depending on the resolution of the selected image on the picturebox. But it seems like the picturebox size is not changing when I change the image... any help?

我正在尝试根据图片框上所选图像的分辨率扩展我的表单。但是，当我更改图像时，似乎图片框大小没有变化...任何帮助？

pictureBox1.ImageLocation = reader["imagem"].ToString();
pictureBox1.Height = pictureBox1.Image.Height;
pictureBox1.Width = pictureBox1.Image.Width;
/*mw and mh are the main width and main heigth,
 i used this in case the user selects another 
 image, then the window returns to it's original
 size before changing again.*/
this.Height = mh;
this.Width = mw;
this.Height += pictureBox1.Image.Height;
this.Width = pictureBox1.Image.Width + 16;
if (this.Width < mw)
{
    this.Width = mw;
}
this.CenterToParent();

This is only the part of the code which I need a fix. The rest is all right and the picturebox is showing the image I select, but it's not changing sizes.

这只是我需要修复的代码的一部分。其余的都没问题，图片框显示我选择的图像，但它没有改变大小。
