how to get phyiscal path of windows service using .net?

Question

I have to get the absolute path of a windows service in a .Net Admin application. I am using ServiceController of .Net as shown below.

ServiceController serviceController = new  ServiceController(serviceName);

But I don't see any property here to get the absolute path of the .exe of the service. Is there anyway to get this programmatically.

You can get this using WMI, which requires an assembly reference to System.Management:

using System.Management;

class Program
{
    static void Main(string[] args)
    {
        Console.WriteLine(GetPathOfService("eventlog"));
        Console.ReadLine();
    }

    public static string GetPathOfService(string serviceName)
    {
        WqlObjectQuery wqlObjectQuery = new WqlObjectQuery(string.Format("SELECT * FROM Win32_Service WHERE Name = '{0}'", serviceName));
        ManagementObjectSearcher managementObjectSearcher = new ManagementObjectSearcher(wqlObjectQuery);
        ManagementObjectCollection managementObjectCollection = managementObjectSearcher.Get();

        foreach (ManagementObject managementObject in managementObjectCollection)
        {
            return managementObject.GetPropertyValue("PathName").ToString();
        }

        return null;
    }
}

If it's not its own assembly you can look in the registry at:

HKLM\System\CurrentControlSet\Services\[servicename]\ImagePath

Or if you mean find your own assembly's path:

Assembly.GetExecutingAssembly().CodeBase;
