看看WMI。 您可以使用System.Management命名空间：

System.Management.ConnectionOptions myConnectionOptions = new System.Management.ConnectionOptions(); myConnectionOptions.Impersonation = System.Management.ImpersonationLevel.Impersonate; System.Management.ManagementScope objwmiservice; System.Management.ManagementObjectSearcher myObjectSearcher; System.Management.ManagementObjectCollection myCollection; try { objwmiservice = new System.Management.ManagementScope( ("\\\\" + (HostOrIP + "\\root\\cimv2")), myConnectionOptions); objwmiservice.Connect(); myObjectSearcher = new System.Management.ManagementObjectSearcher(objwmiservice.Path.ToString(), "Select UserName from Win32_ComputerSystem"); myObjectSearcher.Options.Timeout = new TimeSpan(0, 0, 0, 0, 7000); myCollection = myObjectSearcher.Get(); foreach (System.Management.ManagementObject myObject in myCollection) { if (!(myObject.GetPropertyValue("User name") == null)) { string Userx = myObject.GetPropertyValue("Usernam e").ToString(); int posx = Userx.LastIndexOf("\\"); if ((posx > 0)) { Userx = Userx.Substring((posx + 1)); return Userx.ToUpper(); } } } return ""; } catch (Exception) { return ""; } }
