WMI 查询 - 使用并非在所有操作系统中都可用的属性

Question

Win32_OperatingSystem\OSArchitecture 属性在 Windows 7 上可用，但在 Windows XP 上不可用。我使用 WMI 代码生成器检查了这一点。我应该如何更改以下代码以在两种操作系统（Win XP 和 Win 7）上工作？

ObjectQuery objectQuery = new ObjectQuery("SELECT OSArchitecture FROM Win32_OperatingSystem");
ManagementObjectSearcher searcher = new ManagementObjectSearcher(objectQuery);
if (searcher.Get().Count == 0) // this line throw exception on Windows XP
    return null;

我知道我可以捕获异常，但我正在寻找更好的解决方案

这对我有用：

string strOSArchitecture = "";
ObjectQuery objectQuery = new ObjectQuery("SELECT * FROM Win32_OperatingSystem");
ManagementObjectSearcher searcher = new ManagementObjectSearcher(objectQuery);
ManagementObjectCollection results = searcher.Get();

foreach (ManagementObject result in results)
{
   foreach (PropertyData property in result.Properties)
   {
      else if (property.Name.Equals("OSArchitecture"))
      {
         strOSArchitecture = result["OSArchitecture"].ToString();
      }
   }
}
