如何在C＃代碼中獲取操作系統詳細信息

Question

我需要獲得OsArchitecture的意思是O / s的位數，我使用了Win32_OperatingSystem，但其“ OsArchitecture”不適用於所有類型的操作系統

ManagementObjectSearcher objOSDetails = new ManagementObjectSearcher("SELECT * FROM Win32_OperatingSystem");
           ManagementObjectCollection osDetailsCollection = objOSDetails.Get();
 foreach( ManagementObject mo in osDetailsCollection )
  {
    String  _operatingSysBits = mo["OSArchitecture"].ToString();

  }

Answer 1

檢查IntPtr.Size 。 在32位平台上它將是4，在64位平台上將是8（除非您的進程以32位模式運行）。

Answer 2

對於.NET 4.0，有Environment.is64BitOperatingSystem

要么

    ManagementObject Mo = new ManagementObject("Win32_Processor.DeviceID='CPU0'");
    object o = Mo["Architecture"];
    UInt16 sp = (UInt16)(o);

    if (sp == 0)
    {
        //86
    } else if (sp == 9)
    {
        //64
    }

    Mo.Dispose();
