[HttpPost]
public ActionResult AddImage(Image model)
{
if (model.ImageData != null && model.ImageData.ContentLength > 0)
{
var fileName = Path.GetFileName(model.ImageData.FileName);
var pathBig = Path.Combine(Server.MapPath("~/UploadedImages"), fileName);
var pathSmall = Path.Combine(Server.MapPath("~/UploadedImages"), "small_" + fileName);
// --> How to change image size to big(800 x 600)
// and small (100x80) and save them?
model.ImageData.SaveAs(pathBig);
model.ImageData.SaveAs(pathSmall);
}
}
How do I change the image size to big(800 x 600) to small (100x80) and save them?
You could try this library: http://nuget.org/packages/ImageResizer
It does support asp.net-mvc: http://imageresizing.net/
Or you could get a pure C# lib and use it on your app. See these posts:

And this snippet I found : http://snippets.dzone.com/posts/show/4336
The simplest way of doing it from the framework methods itself will be to use the DrawImage() method of the Graphics Class.
The example code could be like:
//For first scale
Bitmap bmp = new Bitmap(800, 600);
Graphics gf = Graphics.FromImage(bmp);
Image userpic = Image.FromStream(/*pass here the image byte stream*/)
gf.DrawImage(userpic, new Rectangle(0,0,800,600))
gf.Save(/* the save path */);
//For second scale
Bitmap bmp = new Bitmap(100, 80);
Graphics gf = Graphics.FromImage(bmp);
Image userpic = Image.FromStream(/*pass here the image byte stream*/)
gf.DrawImage(userpic, new Rectangle(0,0,100,80))
gf.Save(/* the save path */);
