Question

this will be a noob question.
I’m new to c#

I have a file upload server control that I am using to save images to server.

I have, in my library, an image resize function with this parameter:

byte[] resizeImage(byte[] image, int witdh)

that i am supposed to use.
now, i am saving my file to some path as upImage.saveas(“filepath”);

ok?

now, I want to resize this image and i cant figure how to convert that image to bytes???

where is the article to convert? everywhere i see, i can only see bytes to image but i want other way around..

please help?

Answer 1

Do you mean convert the saved file to a byte[] array? If so, you can use File.ReadAllBytes:

byte[] imageBytes = File.ReadAllBytes("example.jpg");

If you want to grab the byte[] array directly from your FileUpload control then you can use the FileBytes property:

byte[] imageBytes = yourUploadControl.FileBytes;
