如何删除 WMI 类

Question

I have been asked to create an application to manage instances in the WMI.

In previous version of this application the WMI class looks like this

{String Key,String Data}

for the new version the WMI class looks like this

{String Key,String Data1,String Data2} .

Now I'm facing a problem if the WMI class does exist but not in the new format. This might happen for upgrade purposes.

I want to delete the old WMI class and create new one with the new format.

How I can do this?

Answer 1

you can use System.Management your code sould look like this:

    void DeleteClass()
    {
        string ns, cl;
        ns = "nameSpace path";
        cl = "ClassName";
        string serverString = @"\\" + System.Environment.GetEnvironmentVariable("COMPUTERNAME") +ns;
        ManagementScope mScope = new ManagementScope(serverString);
        using (ManagementClass cls = new ManagementClass(mScope, new ManagementPath(cl), new ObjectGetOptions()))
        {
            using (ManagementObjectCollection objCol = cls.GetInstances())
            {
                foreach (ManagementObject obj in objCol)
                {
                    obj.Delete();//cleare the instances
                }
            }
            cls.Delete();//delete the class
        }
    }
