Check the width and height of an image

Question

I am able to display the picture in the picture box without checking the file size by the following code:

private void button3_Click_1(object sender, EventAr         


        

Answer 1

The Bitmap will hold the height and width of the image.

Use the FileInfo Length property to get the file size.

FileInfo file = new FileInfo(open.FileName);
var sizeInBytes = file.Length;

Bitmap img = new Bitmap(open.FileName);

var imageHeight = img.Height;
var imageWidth = img.Width;

pictureBox2.Image = img;
