adding instances to a WMI class using c#

[tzvikaz]

Hi,
I looked all over the web for a simple .NET application that uses .NET
class libraries to create a namespace, create class, add properties to
it and also add intances to this class.
I've seen an example using vbsript but I want to do it using
native .net code.

Can someone please help me with that?

Here is a small sample in C# (but I find this much easier in MOF, especially
when there are more than a few properties and qualifiers to create):



using System;
using System.Management;

namespace WMITest
{
class Program
{
static void Main()
{
// 1. Create a WMI namespace

// Connect to the parent namespace
// and get the WMI system class
// called __Namespace

ManagementClass namespaceClass =
new ManagementClass("Root", "__Namespace", null);

// Create an instance of __Namespace,
// assign its Name property
// and save it to the repository.
// This in fact creates a new WMI namespace.

ManagementObject namespaceInst =
namespaceClass.CreateInstance();

namespaceInst.Properties["Name"].Value = "Test";
namespaceInst.Put();

// 2. Connect to the new namespace
// and create a new class

// Create a ManagementClass instance
// and assign its __Class system property

ManagementClass newClass = new ManagementClass(
"Root\\Test", String.Empty, null);
newClass["__Class"] = "TestClass";

// Add a few properties

newClass.Properties.Add(
"Property1", CimType.String, false);
newClass.Properties["Property1"]
.Qualifiers.Add("Key", true);

newClass.Properties.Add(
"Property2", CimType.SInt32, false);

newClass.Put();

// 3. Create an instance of the new class
// and save it to the repository

ManagementObject newInstance =
newClass.CreateInstance();
newInstance["Property1"] = "KeyValue";
newInstance["Property2"] = 100;

newInstance.Put();

}
}
}
