Hello

Here is my code.

C#

String dnsServerName = "localhost";
            ManagementScope scope =
               new ManagementScope(@"\\" + dnsServerName + "\\root\\MicrosoftDNS");

            scope.Connect();

            ManagementClass cmiClass =
               new ManagementClass(scope,
                                   new ManagementPath("MicrosoftDNS_AType"),
                                   null);

            ManagementBaseObject inParams =
                wmiClass.GetMethodParameters("CreateInstanceFromPropertyData");

            inParams["DnsServerName"] = this.ServerName;
            inParams["ContainerName"] = zone;
            inParams["OwnerName"] = hostName + "." + zone;
            inParams["IPAddress"] = iPAddress;

            cmiClass.InvokeMethod("CreateInstanceFromPropertyData", inParams, null);

I was able to reference 'ManagementClass' successfully.

But I have googled and googled but I don't understand how to reference wmiClass correctly.

Please can some one help me.

Thanks

Not clear what do you mean by referencing a class. What is the problem, exactly?

In C# you reference DLLs so that you can control certain aspects of the computer.

Like you would reference a DLL to change windows colours.

In my case.

I do not understand what to do to reference WmiClass so that I can control my DNS server.

Thanks

OK, you demonstrated that you poorly understand what is referencing the DLL, thank you. Essentially, you reference assembly, no "DLL", which is meaningful in .NET (just a file type). What is "reference a class"? OK, did you add the System.Management reference?

Yes, that was referenced successfully but the WmiClass I don't know what to do.

Thanks

What do you men by that? It depends on what you want to do. Does it compile? If not, what's the error?

Error
The name 'wmiClass' does not exist in the current context

in your case you should use cmiClass instead wmiClass

Sergey Alexandrovich Kryukov 1-May-13 12:49pm

This is because you declare "wmiClass" and spelled "cmiClass" below. Come on, Visual Studio points it out precisely. You need to learn how to read it. And please, read the chapter on .NET assemblies. This is one of the most fundamental things.

Why did you post a comment as a solution to your own question? Be careful not to do that as it can be construed as abuse.

M.R. Inc 1-May-13 11:58am

Well there was no other way to take Ganeshes reply as an answer...

Richard C Bishop 1-May-13 12:00pm

I understand. I just wanted to give you a heads up so you would avoid being reported as an abuser in the future.

No problem.
