C#.Net: WMI Provider,Implem enting Instance operations

[ssnsridhar]

Hi,
I ve saw a sample instance provider and have done a service which wil just display wat i have entered in ma service code.. Now i want to Enumerate, Create, Get, Modify operations. Can anyone plz help me out..

I have included ma code in this.. plz tel how to implement those operations..

using System;
using System.Collecti ons;
using System.Componen tModel;
using System.Data;
using System.Diagnost ics;
using System.ServiceP rocess;
using System.Manageme nt.Instrumentat ion;
using Tel_Dir_Provide r;

namespace Tel_Dir
{
public class Service1 : System.ServiceP rocess.ServiceB ase
{
// this parameter will be exposed by the provider.
private string S_name ="AMI-US";
private long S_ph_no = 7702552663;
private string S_address ="USA";

private System.Componen tModel.Containe r components = null;
Tel_Dir_Provide r.Tel_Dir S_Tel_Dir_Provi der;

public Service1()
{
// This call is required by the Windows.Forms Component Designer.
InitializeCompo nent();
Set_Tel_Dir();
}

// The main entry point for the process
static void Main()
{
System.ServiceP rocess.ServiceB ase[] ServicesToRun;

// More than one user Service may run within the same process. To add
// another service to this process, change the following line to
// create a second service object. For example,
//
// ServicesToRun = new System.ServiceP rocess.ServiceB ase[] {new Service1(), new MySecondUserSer vice()};
//
ServicesToRun = new System.ServiceP rocess.ServiceB ase[] { new Service1() };

System.ServiceP rocess.ServiceB ase.Run(Service sToRun);
}

/// <summary>
/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.
/// </summary>
private void InitializeCompo nent()
{
components = new System.Componen tModel.Containe r();
this.ServiceNam e = "Tel_Dir";
}

private void Set_Tel_Dir()
{
//Create provider instance
S_Tel_Dir_Provi der = new Tel_Dir_Provide r.Tel_Dir();
//set some values
S_Tel_Dir_Provi der.S_Name = S_name;
S_Tel_Dir_Provi der.S_Address = S_address;
S_Tel_Dir_Provi der.S_Ph_No = S_ph_no;
//Makes an instance visible through management instrumentation .
Instrumentation .Publish(S_Tel_ Dir_Provider);
}

/// <summary>
/// Clean up any resources being used.
/// </summary>
protected override void Dispose( bool disposing )
{
if( disposing )
{
if (components != null)
{
components.Disp ose();
}
}
base.Dispose( disposing );
}

/// <summary>
/// Set things in motion so your service can do its work.
/// </summary>
protected override void OnStart(string[] args)
{
Tel_Dir_Synopsi sEvent pje = new Tel_Dir_Synopsi sEvent();
pje.ServiceName = "Telephone Directory";
pje.Method = "Set";
// This will raise the a Tel_Dir_Synopsi sEvent management event.
Instrumentation .Fire(pje);
}


protected override void OnStop()
{
Tel_Dir_Details Event ple = new Tel_Dir_Details Event();
ple.Developer = "Sridhar.G & Prakash.S";
ple.ProjectLead s = "Arun.V & Chitrak";
// This will raise the a Tel_Dir_Details Event management event.
Instrumentation .Fire(ple);
}
}
}

My class file is as follows..

using System;
using System.Manageme nt;
using System.Configur ation.Install;
using System.Manageme nt.Instrumentat ion;


// Define unique namespace.
[assembly:Instru mented("root/CimV2")]

//Installs an instrumented assembly (InstallUtil.ex e).
[System.Componen tModel.RunInsta ller(true)]
public class InstanceInstall er : DefaultManageme ntProjectInstal ler {}



namespace Tel_Dir_Provide r
{

[Instrumentation Class(Instrumen tationType.Even t)]
public class Tel_Dir_Details Event
{
public string Developer;
public string ProjectLeads;
}

[Instrumentation Class(Instrumen tationType.Even t)]
public class Tel_Dir_Synopsi sEvent
{
public string ServiceName;
public string Method;
}

/// define the Telephone Directory provider class.
[Instrumentation Class(Instrumen tationType.Inst ance)]
public class Tel_Dir
{
private string name;
private long phone_no;
private string address;

public Tel_Dir()
{
name="";
phone_no = 0 ;
address="";
}

public string S_Name
{
get
{
return name;
}

set
{
name = value;
}
}

public string S_Address
{
get
{
return address;
}

set
{
address = value;

}
}

public long S_Ph_No
{
get
{
return phone_no;
}

set
{
phone_no = value;

}
}
}
}


Here i have entered the name, phone num and address so it is getting displayed when i start the server.. But i wanna know how to implement Create, Get, Modify etc operations for instance provider..
