如何从相框中获取图片尺寸 [英] How Do I Get Picture Size From A Picture Box

问题描述

大家好，我想在图片框控件中显示图像的大小，我在网上找到的几个例子都是使用openfile对话框控件，但是我没有上传图片，它已经在图片框中了，我试过这个：

Hello everyone, i want to diplay the size of an image in a picturebox control, a few examples i have found online are using openfile dialog control, but i am not uploading the picture, it is already in the picture box, i have tried this:

Image img = Image.FromFile(openDialog.FileName);
double fileWidth = img.Width;
double fileheigth = img.Height;
double fileByte = (((fileWidth) * (fileheigth))/1024);
label2.Text = "Image Size: " + fileByte.ToString() + " KB";

但它似乎不起作用，我将感激任何帮助。在此先感谢

But it doesn't seem to work, please i will appreciate any assitance. Thanks in advance
