c# - Resizing image with MaxHeight and MaxWidth -

i want use answer question here: resize image proportionally maxheight , maxwidth constraints

but image .net image. wondering if there way resize image proportionally maxheight , maxwidth constraint .net image. here asp code looks like:

<asp:image id="image1" runat="server" height="445px" visible="false" width="640px" /> 

the code behind looks this:

image1.imageurl = "/images/" + image1link.tostring(); 

an asp.net image has same attributes of winforms image. still can use image1.height , image1.width. set height & width these attributes. check example:

protected void page_load(system.object sender, system.eventargs e) {     if (!page.ispostback) {         loadimage();     } }  private void loadimage(){     image1.imageurl = loadurlfromdatabase(params);     image1.width = (int)(image.width * ratio);     image1.height = (int)(image.height * ratio); }
