Question

我正在尝试对从AD检索到的计算机名称和我希望从计算机使用WMI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");
                    }
                }
            }
        }

但是我收到了一个ManagementException＆gt;＆gt; dnsHostName = oneName.Properties [“DNSHostName”]。ToString（）; ＆LT;＆LT;这里说没找到。有什么想法吗？

根据您连接到此属性的操作系统，将无法使用。您可以从documentation看到它在Windows 2000和XP上不可用。但是，它可以在Win32_NetworkAdapterConfiguration类中使用，但是您将收到多个对象，您必须循环才能获取名称，因为大多数对象都将为null。

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。
