I'm very new to .Net, C# and Visual Studio. Now I want to develop a Windows Service application using C#. The Windows Service needs to write some data to some file. I'm using Visual Studio 2010. I'm using Windows XP as my operating system. I created a windows service.its installer etc.
When I install the Windows Service in the folder other than non-default folder (other than C drive), after running service it will create the file and write the text file success.
When I install the service in the default location (that when the time of installation the i cannot the default path) (please refer the attached image)

Then after installing then I run the service. But the file is not created and there is no exception thrown. The following are the codding snippet for file.
string logPath = AppDomain.CurrentDomain.BaseDirectory + "log\CastrolSdWindowsService_Log.txt";

fs = new FileStream(logPath, FileMode.Append, FileAccess.Write);
                fs.Write(bytes, 0, bytes.Length);
                fs.Flush();

I cannot find why the file is not created in C drive.
