C# 解析WMI DNS主机名

我正在尝试将从AD检索到的计算机名与使用WMI从该计算机获取的DNS主机名进行比较

我目前有：

foreach (SearchResult oneMachine in allMachinesCollected)
            {
                pcName = oneMachine.Properties["name"][0].ToString();
                ConnectionOptions setupConnection = new ConnectionOptions();
                setupConnection.Username = USERNAME;
                setupConnection.Password = PASSWORD;
                setupConnection.Authority = "ntlmdomain:DOMAIN";
                ManagementScope setupScope = new ManagementScope("\\\\" + pcName + "\\root\\cimv2", setupConnection);
                setupScope.Connect();

                ObjectQuery dnsNameQuery = new ObjectQuery("SELECT * FROM Win32_ComputerSystem");
                ManagementObjectSearcher dnsNameSearch = new ManagementObjectSearcher(setupScope, dnsNameQuery);
                ManagementObjectCollection allDNSNames = dnsNameSearch.Get();
                string dnsHostName;
                foreach (ManagementObject oneName in allDNSNames)
                {
                    dnsHostName = oneName.Properties["DNSHostName"].ToString();
                    if (dnsHostName == pcName)
                    {
                        shutdownMethods.ShutdownMachine(pcName, USERNAME, PASSWORD);
                        MessageBox.Show(pcName + " has been sent the reboot command");
                    }
                }
            }
        }

但是我得到了一个ManagementException>>dnsHostName=oneName.Properties[“dnsHostName”].ToString（） 根据您连接到此属性的操作系统的不同，此属性将不可用。从中可以看出，它在Windows 2000和XP上不可用。但是，它在Win32_NetworkAdapterConfiguration类上可用，但您将收到多个对象，您必须循环这些对象才能获得名称，因为其中大多数对象都为空

另外，

dnsHostName=oneName.Properties[“dnsHostName”].ToString（）不正确。它应该是
dnsHostName=oneName.Properties[“dnsHostName”].Value.ToString（）
。同样，如果您决定使用Win32_NetworkAdapterConfiguration，请记住它可以为null
