如何檢查C＃中的Windows許可證狀態？

Question

我想我的程序檢查的Windows 10已經被激活

我有以下代碼

public static bool IsWindowsActivated() 
    { 
     bool activated = true; 
     ManagementScope scope = new ManagementScope(@"\\" + System.Environment.MachineName + @"\root\cimv2"); 
     scope.Connect(); 

     SelectQuery searchQuery = new SelectQuery("SELECT * FROM Win32_WindowsProductActivation"); 
     ManagementObjectSearcher searcherObj = new ManagementObjectSearcher(scope, searchQuery); 

     using (ManagementObjectCollection obj = searcherObj.Get()) 
     { 
      foreach (ManagementObject o in obj) 
      { 
       activated = ((int)o["ActivationRequired"] == 0) ? true : false; 
      } 
     } 
     return activated; 
    } 

嘗試使用此代碼時，調試器抱怨Invalid class，我不知道是什麼是

我該怎麼辦才能解決這個問題？或者有沒有其他方法來檢查Windows的許可證狀態？

WMI類Win32_WindowsProductActivation僅在Windows XP上受支持。對於Windows 10，您需要使用SoftwareLicensingProduct

public static bool IsWindowsActivated() 
{ 
    ManagementScope scope = new ManagementScope(@"\\" + System.Environment.MachineName + @"\root\cimv2"); 
    scope.Connect(); 

    SelectQuery searchQuery = new SelectQuery("SELECT * FROM SoftwareLicensingProduct WHERE ApplicationID = '55c92734-d682-4d71-983e-d6ec3f16059f' and LicenseStatus = 1"); 
    ManagementObjectSearcher searcherObj = new ManagementObjectSearcher(scope, searchQuery); 

    using (ManagementObjectCollection obj = searcherObj.Get()) 
    { 
     return obj.Count > 0; 
    } 
}
