Instance Class

Represents derived classes known to be management instrumentation instance classes. These derived classes inherit an implementation of IInstance that allows instances to be published through the Published property.

For a list of all members of this type, see Instance Members.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.

Example

[C#] 
using System;
using System.Management;
using System.Configuration.Install;
using System.Management.Instrumentation;

// This sample demonstrates how to create a Management Instrumentation Instance
// class and how to publish an instance of this class to WMI.

// Specify which namespace the Instance class is created in
[assembly:Instrumented("Root/Default")]

// Let the system know InstallUtil.exe utility will be run against
// this assembly
[System.ComponentModel.RunInstaller(true)]
public class MyInstaller : DefaultManagementProjectInstaller {}

// Create a Management Instrumentation Instance class
[InstrumentationClass(InstrumentationType.Instance)]
public class InstanceClass : Instance
{
    public string SampleName;
    public int SampleNumber;
}

public class Sample_InstanceProvider
{
    public static int Main(string[] args) {
        InstanceClass instClass = new InstanceClass();
        instClass.SampleName = "Hello";
        instClass.SampleNumber = 888;
   
        // Publish this instance to WMI
        instClass.Published = true;
