Image Display

I am having a problem in displaying an image on my web page.

I always get:
UnauthorizedAccessException: Access to the path D:\ASP.NET Practice\WebControls\Images is denied.

This is the code that i am using:

C#

string Url, filename;
byte[] imageBytes;
filename = FUload.FileName;
Url = HttpContext.Current.Server.MapPath("~/Images" );
imageBytes = FUload.FileBytes;
File.WriteAllBytes(Url, imageBytes);
Img.ImageUrl = Url + filename;

I have set secutiry permission for ASP.NET user but it still gives the same problem.

Please, can anyone help me in resolving this issue?
Thanks

Solution 1

Error is pretty straight forward. It's a security permissions issue.

Are you using any kind of 'impersonation'? Either in your Web.Config file or in IIS? If so, then you need to give that user correct permissions.
In case of impersonation, ASPNET is not the one accessing the path.

BTW: there is a typo (or mistake?) in line:

C#

Url = HttpContext.Current.Server.MapPath("~/Images" );

Forward slash is missing at the end. It should be:

C#

Url = HttpContext.Current.Server.MapPath("~/Images/" );

Ok. But I have updated my answer. Have a loot at it. I think, which looked to me a typo earlier was your mistake. 'Forward Slash' was missing.,.. try that, it should work too.

I got another way that did not give all those
security problems

this is the code below

string filename,ext ,fullname;

Random guid = new Random();

fullname = FUload.FileName;
ext = Path.GetExtension(fullname);
filename = guid.ToString() + ext;

FUload.SaveAs(MapPath("~/Images/" + filename ));

Img.ImageUrl = "~/Images/" + filename;
