在C#中确定操作系统和处理器类型

Question

我想要检查我正在使用的操作系统和处理器类型。这应该在运行时检查。我尝试使用

System.Environment.GetEnvironmentVariable("PROCESSOR_ARCHITECTURE")

和

System.OperatingSystem osInfo2 = System.Environment.OSVersion;
Console.WriteLine(osInfo2.ToString());

但这只是VS运行的环境而已。
有人告诉我要使用WMI来检查，但我不知道如何操作。 有人可以帮我吗？

获取操作系统信息：

var wmi =
    new ManagementObjectSearcher( "select * from Win32_OperatingSystem" )
    .Get()
    .Cast<ManagementObject>()
    .First();

OS.Name = ((string)wmi["Caption"]).Trim();
OS.Version = (string)wmi["Version"];
OS.MaxProcessCount = (uint)wmi["MaxNumberOfProcesses"];
OS.MaxProcessRAM = (ulong)wmi["MaxProcessMemorySize"];
OS.Architecture = (string)wmi["OSArchitecture"];
OS.SerialNumber = (string)wmi["SerialNumber"];
OS.Build = ((string)wmi["BuildNumber"]).ToUint();

获取CPU信息：

var cpu =
    new ManagementObjectSearcher( "select * from Win32_Processor" )
    .Get()
    .Cast<ManagementObject>()
    .First();

CPU.ID = (string)cpu["ProcessorId"];
CPU.Socket = (string)cpu["SocketDesignation"];
CPU.Name = (string)cpu["Name"];
CPU.Description = (string)cpu["Caption"];
CPU.AddressWidth = (ushort)cpu["AddressWidth"];
CPU.DataWidth = (ushort)cpu["DataWidth"];
CPU.Architecture = (CPU.CpuArchitecture)(ushort)cpu["Architecture"];
CPU.SpeedMHz = (uint)cpu["MaxClockSpeed"];
CPU.BusSpeedMHz = (uint)cpu["ExtClock"];
CPU.L2Cache = (uint)cpu["L2CacheSize"] * (ulong)1024;
CPU.L3Cache = (uint)cpu["L3CacheSize"] * (ulong)1024;
CPU.Cores = (uint)cpu["NumberOfCores"];
CPU.Threads = (uint)cpu["NumberOfLogicalProcessors"];

CPU.Name =
   CPU.Name
   .Replace( "(TM)", "™" )
   .Replace( "(tm)", "™" )
   .Replace( "(R)", "®" )
   .Replace( "(r)", "®" )
   .Replace( "(C)", "©" )
   .Replace( "(c)", "©" )
   .Replace( "    ", " " )
   .Replace( "  ", " " );

是的，WMI是做这种事情的最佳方式。您可以使用它来检索操作系统信息：

ManagementObjectSearcher objMOS = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM  Win32_OperatingSystem");

使用以下代码来确定操作系统：

string OPSystemVersion = Environment.OSVersion.ToString();

要确定CPU的名称和类型，首先需要在您的项目中添加System.Management引用，然后可以使用以下代码：

public static string SendBackProcessorName()
        {
            ManagementObjectSearcher mosProcessor = new ManagementObjectSearcher("SELECT * FROM Win32_Processor");
            string Procname = null;

            foreach (ManagementObject moProcessor in mosProcessor.Get())
            {
                if (moProcessor["name"] != null)
                {
                    Procname = moProcessor["name"].ToString();

                }

            }

            return Procname;
        }

看看ManagementClass类： http://msdn.microsoft.com/zh-cn/library/system.management.managementclass.aspx

var mgmt = new ManagementClass("Win32_OperatingSystem");
foreach (ManagementObject mgmtObj in mgmt.GetInstances())
{                
    // Just get first value.
    return mgmtObj[info.Information].ToString().Trim();
}
