WMI deprecated: how to query from .Net Core now?
As of my knowledge cutoff in September 2021, WMI (Windows Management Instrumentation) is not deprecated. However, if there are any changes or deprecations in recent versions, please refer to the latest Microsoft documentation for the most up-to-date information.
Regarding querying from .NET Core, you can use the System.Management
namespace to interact with WMI. The System.Management
namespace provides classes and methods for querying and managing WMI data in .NET applications.
Here's an example of how to query WMI using .NET Core:
csharpusing System;
using System.Management;
class Program
{
static void Main(string[] args)
{
try
{
// Connect to WMI namespace
var scope = new ManagementScope(@"\\.\root\cimv2");
scope.Connect();
// Define WQL query
var query = new ObjectQuery("SELECT * FROM Win32_Process");
// Create ManagementObjectSearcher
var searcher = new ManagementObjectSearcher(scope, query);
// Execute the query and retrieve the results
var results = searcher.Get();
// Process the results
foreach (var result in results)
{
// Access properties of each result object
var processName = result["Name"];
Console.WriteLine(processName);
}
}
catch (ManagementException e)
{
Console.WriteLine($"An error occurred: {e.Message}");
}
}
}
In the above example:
The
System.Management
namespace is imported to access WMI-related classes and methods.The
ManagementScope
class is used to connect to the desired WMI namespace. In this case, we connect to theroot\cimv2
namespace on the local machine.An
ObjectQuery
is created with the desired WQL (WMI Query Language) query. In this example, we select all processes from theWin32_Process
class.A
ManagementObjectSearcher
is created with the specified scope and query.The
Get()
method is called on theManagementObjectSearcher
to execute the query and retrieve the results.The results are looped through, and properties of each result object are accessed and processed.
This example demonstrates the basic usage of querying WMI using .NET Core. Modify the query and process the results based on your specific requirements.
Note that the availability of specific WMI classes and properties may vary depending on the operating system and WMI provider. Consult the Microsoft documentation for the relevant WMI classes and properties based on your target environment.
