System.Unauthorized Exception

*

Exception =System.Net.WebException: Access to the path 'c:\windows\system32\inetsrv\Dialer' is denied. ---> System.UnauthorizedAccessException: Access to the path 'c:\windows\system32\inetsrv\Dialer' is denied. at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
at System.IO.FileStream.Init(String path, FileMode mode, FileAccess access, Int32 rights, Boolean useRights, FileShare share, Int32 bufferSize, FileOptions options, SECURITY_ATTRIBUTES secAttrs, String msgPath, Boolean bFromProxy, Boolean useLongPath) at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access, FileShare share, Int32 bufferSize, FileOptions options, String msgPath, Boolean bFromProxy) at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access, FileShare share) at System.Net.FileWebStream..ctor(FileWebRequest request, String path, FileMode mode, FileAccess access, FileShare sharing) at System.Net.FileWebRequest.GetRequestStreamCallback(Object state)
--- End of inner exception stack trace --- at System.Net.WebClient.UploadDataInternal(Uri address, String method, Byte[] data, WebRequest& request) at System.Net.WebClient.UploadString(Uri address, String method, String data)

*

Code where the exception is occurring

using (var writer = new StringWriter())
    {
       JsonSerializer.Create().Serialize(writer, payLoad);
       var result =client.UploadString(commDialerApiUrl,writer.ToString());
       return ((T)JsonConvert.DeserializeObject(result, typeof(T)));
    }

I know the code above is not ideal, however I just need to understand why even an attempt to access is made. Can anyone provide some insight please?

All right, the issue was very simple. The code was trying to make a Restful post to a blank Uri. Since the Uri was blank webclient was trying to resolve the call to a file (having the same name as the service) in inetpub.

Since no such file path was invalid, thus the i/o error.
