Using WMI in C# to Enumerate Registry Values and Keys

[DeepT]

I have been beating my head against the wall trying out how to do this. I know it is a simply syntactical problem. I do not know how to form the query string.

I have been digging and digging and all I can find VBS scripts that do this and I have no idea how to do the equivalent in C#. I do know how to do some things, like look at processes or services. They do not need additional parameters, you just call the function and look at the responses.

IE:

//Make a connection to a remote computer using these options
		ManagementScope scope = new ManagementScope("\\\\198.31.1.1\\root\\cimv2", options);
		scope.Connect();


		// Build a query for enumeration of Win32_Environment instances
		SelectQuery query = new SelectQuery("Win32_Process");

		// Instantiate an object searcher with this query
		ManagementObjectSearcher searcher = new ManagementObjectSearcher(query); 

		// Call Get() to retrieve the collection of objects and loop through it
		foreach (ManagementBaseObject envVar in searcher.Get())
			Console.WriteLine("Variable : {0}, Value = {1}", 
				envVar["Name"],envVar["ExecutablePath"]);

Now how do you turn that into one that can enumerate all keys under HKLM / SOFTWARE?

The only part I know I have right, or at least I think I do is :

ManagementScope scope = new ManagementScope("\\\\198.31.1.1\\root\\default:StdRegProv", options);

What I don't know what to is how to change this:

SelectQuery query = new SelectQuery("Win32_Process");

Secondly:
How are you supposed to find out what everything looks like so you can make queries for any objects and then know what 'values' to look for? I can't find any list of all the 'objects' I query, let alone adding things like all the values and whatnot assocated with them.

At best I find hoards of VBS scripts using WMI and I have no how to translate them into a C# query call.

For example:

HKLM = 2147483650 ;HKEY_LOCAL_MACHINE
sRegPath = "SYSTEM\CurrentControlSet\Services\Eventlog\System";

oLoc = CreateObject("WbemScripting.SWbemLocator")
oSvc = oLoc.ConnectServer(computername, "root/default",user,password)
oReg = oSvc.Get("StdRegProv")
oMethod = oReg.Methods_.Item("EnumKey");
oInParam = oMethod.InParameters.SpawnInstance_();
oInParam.hDefKey = HKLM;
oInParam.sSubKeyName = sRegPath;
oOutParam = oReg.ExecMethod_(oMethod.Name, oInParam);    
aNames = oOutParam.sNames;

subkeylist = ""

for i = 0 to ArrInfo(aNames,6)-1
	 name = aNames[i]
    ;Message("Subkeys", StrCat("KeyName: ", name));
    subkeylist = StrCat(subkeylist,@tab,name)
Next
subkeylist = StrTrim(subkeylist)
AskItemList(sRegPath,subkeylist,@tab,@unsorted,@single)

Is a VBS script that uses WMI to enum SYSTEM\CurrentControlSet\Services\Eventlog\System registry.

Which is pretty much what I want to do, but again, I have no idea how to do that in C# using WMI.

Nobody has any ideas on this? I posted this on the MS dotnet forums, and didn't get any answers either. This can't be that obscure, can it?
