Window Service & C#

[=?Utf-8?B?UG90c2FuZw==?=]

Hi,

I have a window service program created in c#. The window service program is
installed and running. In the mean time, I have another c# application, I
would like to know if there is a way to find out in this c# application where
(the complete path)the window service program is running from. Can someone
provide the sample code?
Thanks.

I use string
startpath=Path. GetDirectoryNam e(Environment.C ommandLine.Repl ace('"',' '));

Here is a sample code..

Process[] processList = Process.GetProc esses();
string processPath = string.Empty;
//Get the list of current processes running on your machine

foreach (Process proc in processList)
{
//Compare the processName with your process name
if (proc.ProcessNa me == "YourProcessNam e")
{
//The MainModule.File Name returns the complete path of
//the exe that it is running from
processPath = proc.MainModule .FileName;
}

}
System.Console. WriteLine(proce ssPath);

Here is the more refined code than man previous one...

using System.Diagnost ics
Process p = Process.GetProc essesByName("Yo urProcessName") ;
string processPath = p.MainModule.Fi leName;

Hi Potsang,

Thinathayalan's reply has shown how to enumerate all the running processes
to find your "Windows Service" and get its full path. I think it should
meet your need. I want to provide some more information to you.

If you want to retrieve the full path to the "Windows Service" when it is
not running, you can not use System.Diagnost ics.Process class solution. In
this requirement, you have to use QueryServiceCon fig Win32 API to obtain
the installed service binary full path. However, .Net did not expose this
QueryServiceCon fig API from class library, so you have to p/invoke to call
it. You may use the logic below:
1. Use ServiceControll er.GetServices method to retrieve all the services
installed on your system.
2. Enumerate through this services list and compare
ServiceControll er.ServiceName property to find your service
ServiceControll er reference.
3. Then p/invoke QueryServiceCon fig win32 API by passing
ServiceControll erServiceHandle .handle to it. The retrieved
QUERY_SERVICE_C ONFIG structure has a field of lpBinaryPathNam e, which
contains the full binary path of the service.

My original reply below contains some more information:

Hope this helps.

Nothing easier than using System.Manageme nt for this.
string objPath = "Win32_Service. Name='spooler'" ;
string servicePath = null;
using(Managemen tObject service = new ManagementObjec t( new ManagementPath( objPath)))
{
servicePath = (string)service .Properties["PathName"].Value;
}
....

No need to go down the PInvoke route, System.Manageme nt contains all classes needed to
perform management tasks like this, isn't the purpose of the FCL to eliminate the need to
call into Win32 just like we do from unmanaged code?

Hi Willy ,

Oh, thank you for sharing the WMI solution! Yes, Win32_Service should be a
correct solution and by using System.Manageme nt we can use WMI in .Net
without p/invoke unmanaged code.

I am always a Win32 API guy, so I seldom thought solution from WMI
perspective :-)

Thanks.

Jeffrey,

I'm a Win32 guy too, however, System.Manageme nt/WMI virtualizes Win32 which guarantees you
to do the right thing. Another great advantage is that you don't need to run in an
administrator account to perform administrative tasks, something you will appreciate when
moving to Vista.

Willy.

The easiest way to get the path to a service.

/// <summary>
/// Fully-qualified path to the service binary file that
implements the
/// service
/// </summary>
/// <param name="serviceNa me">string</param>
/// <returns>string </returns>
public static string GetPathName(str ing serviceName)
{
string buffer;
ConnectionOptio ns _co = null;
ManagementScope _ms = null;
ManagementObjec t _mo = null;
try
{
_co = new ConnectionOptio ns();
_co.Impersonati on = ImpersonationLe vel.Impersonate ;
_ms = new ManagementScope (@"root\CIMV2 ", _co);
_ms.Connect();

_mo = new
ManagementObjec t(String.Format ("Win32_Service .Name='{0}'",
serviceName));

buffer =
Convert.ToStrin g(_mo.GetProper tyValue("PathNa me"));
}
finally
{
_mo.Dispose();
_mo = null;

if (_ms != null)
{
_ms = null;
if (_co != null)
{
_co = null;
}
}
}
return buffer;
}
