I am working on a program that gathers information about the machine for troubleshooting purposes. After some work on the program running as admin, I couldn't get it to output all the files in the %windir%\drivers properly. I also ran into issues with the current users appdata where it throws a UnauthorizedAccessException and doesn't output anyhing. I though okay, I'll write a service to fix this. After getting a basic service down for testing. I'm still not seeing output. Here is the code for the service:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Diagnostics;
using System.Globalization;
using System.IO;
using System.Linq;
using System.ServiceProcess;
using System.Text;
using System.Threading.Tasks;
namespace SVCTest
{
public partial class Service1 : ServiceBase
{
public Service1()
{
InitializeComponent();
}
protected override void OnStart(string[] args)
{
while (true)
{
OutputDirStructureToFile(
Environment.GetEnvironmentVariable("userprofile") + "\\Desktop\\" + Path.GetRandomFileName() + ".txt",
Environment.ExpandEnvironmentVariables("windir") + "\\drivers");
System.Threading.Thread.Sleep(30000);
}
}
protected override void OnStop()
{
}

private void OutputDirStructureToFile(string outputFileName, string folder)
{
using (var file = new StreamWriter(outputFileName))
{
file.Write(GetFileStrucutre(new DirectoryInfo(folder), "*.*"));
}
}
private string GetFileStrucutre(DirectoryInfo dirInfo, string searchPattern)
{
StringBuilder sb = new StringBuilder();
sb.AppendLine();
sb.AppendLine("Root " + dirInfo.Root);
sb.AppendLine();
sb.Append(GetFileStructureRecursive(dirInfo, searchPattern));
return sb.ToString();
}
private string GetFileStructureRecursive(DirectoryInfo dirInfo, string searchPattern)
{
StringBuilder sb = new StringBuilder();
sb.AppendLine("\r\n Directory of " + dirInfo.FullName + "\r\n");
foreach (var x in dirInfo.GetFileSystemInfos(searchPattern))
{
sb.AppendLine(
x.LastWriteTime.ToString("yyyy-MM-dd HH:mm:ss", CultureInfo.InvariantCulture).PadRight(25)
+ x.Name.PadRight(50)
);
}
foreach (var dir in dirInfo.GetDirectories())
{
sb.Append(GetFileStructureRecursive(dir, searchPattern));
}
//try
//{
// foreach (var dir in dirInfo.GetDirectories(searchPattern))
// {
// sb.AppendLine(

// );
// }
//}
//catch (UnauthorizedAccessException) { }
//try
//{

}
}
You will notice that I commented out a chunk thinking I may be accessing too much info at once. Here is what I am getting after installing and starting the service:

Definitely missing some key drivers in there. For the life of me I can't figure out why it isn't gathering the information. There is no AV running, just updated Windows 7 and VS. I checked for any odd file filter manager drivers but I'm not seeing any.
