Question

I got beginners question.

How to save a file stream to a file on server?!

I got this:

var source = Request.QueryString["src"];
WebClient webclient = new WebClient();
using (Stream stream = webclient.OpenRead(source))
{
   Bitmap iconbitmap = new Bitmap(System.Drawing.Image.FromStream(stream));
   FileStream os = new FileStream("./asdasdasd.ico", FileMode.Create);

   var ic = MakeIcon(iconbitmap, 16, false); /// function returns an icon

   ic.Save(os);
}

My problem is than when I run code in ASP.NET Development Server it saves “asdasdasd.ico” into:
C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\asdasdasd.ico

And, when I run it on remote server got error.

I want to save it into:
http://www.my-web-site.com/output/asdasdasd.ico

Thank you very much.

Answer 1

Use Server.MapPath() (also a using block for closing the file would help):

using(FileStream os = new FileStream(Server.MapPath("/output/asdasdasd.ico"), FileMode.Create))
{
   var ic = MakeIcon(iconbitmap, 16, false); /// function returns an icon
   ic.Save(os);
}
