How to resize images before upload using c#Asp.net

Question

I am learning. net mvc 4 and would like to know if there is any good and simple library, to resize images before uploading, I googled and only found complex functions with resizing calculations made in hand. As this is something very common, I believe there is some library ready and functional for this task. Anyone knows any?

Answer 1

found that the library System.Web.Helpers has a class called WebImage. It is possible to resize the image and save the upload. I just needed a logic to find the right height, because it doesn’t allow you to pass only width or height as a parameter, so the code went like this:

int width = 800;
int height = (int)Math.Round(((width * 1.0) / image.Width) * image.Height);
image.Resize(width, height);
image.Save(path + fileName);
