Web Service, StreamWriter and System.UnauthorizedAccessException.

[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.UnauthorizedAccessException: Access to
'C:\WINDOWS\system32\TestOut.txt' denied.
in System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
in System.IO.FileStream.Init(String path, FileMode mode, FileAccess
access, Int32 rights, Boolean useRights, FileShare share, Int32 bufferSize,

in System.IO.StreamWriter..ctor(String path, Boolean append, Encoding
encoding, Int32 bufferSize)
in System.IO.StreamWriter..ctor(String path)

The code contained in Test.asmx is this:

<%@ WebService Language="C#" Class="WS.HelloWorldWS" %>

using System.IO;
using System.Web.Services;

namespace WS
{
[WebService(Namespace="http://microsoft.com/webservices/")]
public class HelloWorldWS: WebService
{
[WebMethod]
public string HelloWorld()
{
using(StreamWriter sw = new StreamWriter("TestOut.txt"))
{
sw.WriteLine("Hello world");
return "Hello World";
}
}
}
}
Thanks,
Luigi.

That file is being written to the C:\Windows\System32 directory. The very
HEART of the O/S. It should be denied.

namespace WS

[WebService(Namespace="http://microsoft.com/webservices/")]

public string HelloWorld()
{
using(StreamWriter sw = new StreamWriter("TestOut.txt"))
{
sw.WriteLine("Hello world");
return "Hello World";
}
}
}
}

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(StreamWriter sw = new StreamWriter("TestOut.txt"))

Try:

using(StreamWriter sw = new StreamWriter(Server.MapPath("TestOut.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!
