Here's a straignt C# / P/Invoke solution.

        /// 

    /// Returns true if the specified service is running, or false if it is not present or not running.
    /// 
    /// Name of the service to check.
    /// Returns true if the specified service is running, or false if it is not present or not running.
    static bool IsServiceRunning(string serviceName)
    {
        bool rVal = false;
        try
        {
            IntPtr smHandle = NativeMethods.OpenSCManager(null, null, NativeMethods.ServiceAccess.ENUMERATE_SERVICE);
            if (smHandle != IntPtr.Zero)
            {
                IntPtr svHandle = NativeMethods.OpenService(smHandle, serviceName, NativeMethods.ServiceAccess.ENUMERATE_SERVICE);
                if (svHandle != IntPtr.Zero)
                {
                    NativeMethods.SERVICE_STATUS servStat = new NativeMethods.SERVICE_STATUS();
                    if (NativeMethods.QueryServiceStatus(svHandle, servStat))
                    {
                        rVal = servStat.dwCurrentState == NativeMethods.ServiceState.Running;
                    }
                    NativeMethods.CloseServiceHandle(svHandle);
                }
                NativeMethods.CloseServiceHandle(smHandle);
            }
        }
