Web Service, StreamWriter and System.Unauthor izedAccessExcep tion.

[BLUE]

I've created a folder named TestDir in my wwwroot and I've created the
associated virtual application from IIS management snap-in.

I've given full control to TestDir to:
IUSR, ASPNET, Network service, Anonimous access, Everyone, Users, VS
Developers

I've set write access and low application protection from IIS management
snap-in.

Please help me because I'm going crazy!
I get this exception:

System.Unauthor izedAccessExcep tion: Access to
'C:\WINDOWS\sys tem32\TestOut.t xt' denied.

using System.IO;
using System.Web.Serv ices;

namespace WS
{
[WebService(Name space="http://microsoft.com/webservices/")]

public string HelloWorld()
{
using(StreamWri ter sw = new StreamWriter("T estOut.txt"))
{
sw.WriteLine("H ello world");
return "Hello World";
}
}
}
}
Thanks,

That file is being written to the C:\Windows\Syst em32 directory. The very
HEART of the O/S. It should be denied.

You need to have a Web or App.config file that has the pathing to where
Testout.txt should be written and read that pathing from the config file.

using(StreamWri ter sw = new StreamWriter("T estOut.txt"))

Try:

using(StreamWri ter sw = new StreamWriter(Se rver.MapPath("T estOut.txt")))

Thank you so much!!!!!!

I thought the path was the asmx path; seeing that error I was wandering if I
had to use some ASP.Net directive but I have never used ASP.
Thank you very much, you have saved me!
Bye,
