c# - Win32_Service is missing -

-

i have c# code tries load property wmi object - win32_service. returns me 'system.management.managementexception: invalid class ' error.

my simplified code:

static void main(string[] args) {     string servicename = "appfabriceventcollectionservice";     string propertyname = "startname";     var obj = getproperty(servicename, propertyname); }  private static string getproperty(string servicename, string propertyname) {     using (managementobject obj2 = getwindowsservicemanagementobject(servicename))     {         return (obj2.getpropertyvalue(propertyname) string);     } } public static managementobject getwindowsservicemanagementobject(string servicename) {     return new managementobject(string.format("win32_service.name='{0}'", servicename)); }

also i've tried load list of wmi objects powershell command -

get-wmiobject -list | select name

it returns 91 objects, misses win32_service object. googled how reinstall it, didn't found it. there way reinstall somehow?

thank you

update 1: output powershell command:

ps c:\windows\system32> get-wmiobject win32_service get-wmiobject : invalid class "win32_service" @ line:1 char:1 + get-wmiobject win32_service + ~~~~~~~~~~~~~~~~~~~~~~~~~~~     + categoryinfo          : invalidtype: (:) [get-wmiobject], managementexce    ption     + fullyqualifiederrorid : getwmimanagementexception,microsoft.powershell.c    ommands.getwmiobjectcommand

see section "i’m getting 0x80041010 (“invalid class”) error" here. might find useful, in particular use of scriptomatic , wbemtest.
