c# - Use ServiceController and ServiceControllerPermission class to check the status of a service -

i working on application checks status of services running on remote machine. want non-administrative account. logon account launch application can browse , check status of services running on remote machine via "services.msc". using servicecontroller class query status of service:

servicecontroller controller = new servicecontroller(servicename, machinename); if (controller.status != servicecontrollerstatus.running) {    // something. } 

when use non-admin account above line fails "access denied" exception. blogs suggested can use servicecontrollerpermission class check , assert permission on service before executing above code. not exception when try demand or assert permission on service.

servicecontrollerpermission permission = new servicecontrollerpermission(servicecontrollerpermissionaccess.browse, machinename, servicename); permission.demand();  permission.assert(); if (controller.status != servicecontrollerstatus.running) {     // something. } 

there not information on msdn on security requirements servicecontroller or servicecontrollerpermission class.

could tell me right way use servicecontroller class check status of service.
