如何在C＃代码中获取操作系统详细信息

Question

我需要获得OsArchitecture意味着O / s的比特，我使用的是Win32_OperatingSystem，但它的“OsArchitecture”并不适用于所有类型的操作系统

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

  }

Answer 1

检查IntPtr.Size。它在32位平台上为4，在64位平台上为8（除非您的进程在32位模式下运行）。

Answer 2

对于.NET 4.0，有Environment.is64BitOperatingSystem

或

    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();
