I want to make changes to the config of Microsoft Windows UWF Filter ( uwfmgr.exe
) via WMI in C#. Now certain changes can only be done to a specific instance of the WMI class due to their nature. For example:
var scope = new ManagementScope(@"root\standardcimv2\embedded");
using (var uwfClass = new ManagementClass(scope.Path.Path, "UWF_Servicing", null))
{
var instances = uwfClass.GetInstances();
foreach (var instance in instances)
{
Console.WriteLine(instance.ToString());
}
}
This code prints:
\\COMPUTER\root\standardcimv2\embedded:UWF_Servicing.CurrentSession=true
\\COMPUTER\root\standardcimv2\embedded:UWF_Servicing.CurrentSession=false
The changes can only be done to the instance where CurrentSession = false.
How can I get this instance in a clean way?
In other words, I dont want to do:
instance.ToString().Contains("CurrentSession=false")
I believe there is a "nicer" way to do this. Thanks in advance!
You can use SQL for WMI WHERE clause queries, something like this:
var searcher = new ManagementObjectSearcher(
@"ROOT\StandardCimv2\embedded",
@"SELECT * FROM UWF_Servicing WHERE CurrentSession = FALSE");
foreach (ManagementObject obj in searcher.Get())
{
... etc ...
}
But you can also use the object's properties (values types will map to standard .NET's types), like this:
var searcher = new ManagementObjectSearcher(
@"ROOT\StandardCimv2\embedded",
@"SELECT * FROM UWF_Servicing");
foreach (ManagementObject obj in searcher.Get())
{
var currentSession = obj.GetPropertyValue("CurrentSession");
if (false.Equals(currentSession))
{
... etc ...
}
}
