Question

我正在使用实用工具逻辑的.NET Standard类库开发UWP应用。在此应用程序中，我需要收集一些与运行PC相关的元数据

我想出了以下结构来读取数据

 public static void LoadSystemInfo(this Payload payload)
        {
            payload.SystemInfo = new SystemInfo
            {
                Machine = new Machine
                {
                    SerialNumber = SystemInfo("SerialNumber"),
                    UuId = SystemInfo("UuId"),
                },
                HostName = SystemInfo("HostName"),
                OsVersion = SystemInfo("OsVersion"),
                OsManufacturer = SystemInfo("OsManufacturer"),
                DeviceId = SystemInfo("DeviceId"),
                SystemManufacturer = SystemInfo("SystemManufacturer"),
                SystemModel = SystemInfo("SystemModel"),
                SystemType = SystemInfo("SystemType"),
                SystemLocale = SystemInfo("SystemLocale"),
                TimeZone = SystemInfo("TimeZone"),
                TotalPhysicalMemory = SystemInfo("TotalPhysicalMemory"),
                AvailablePhysicalMemory = SystemInfo("AvailablePhysicalMemory"),
            };
        }
        private static string  SystemInfo(string key)
        {
            switch (key)
            {
                case "SerialNumber":
                    return GetMotherBoardId();
                case "UuId":
                    return "";
                case "HostName":
                    return "";
                case "OsVersion":
                    return "";
                case "OsManufacturer":
                    return "";
                case "DeviceId":
                    return "";
                case "SystemManufacturer":
                    return "";
                case "SystemModel":
                    return "";
                case "SystemType":
                    return "";
                case "SystemLocale":
                    return "";
                case "TimeZone":
                    return "";
                case "TotalPhysicalMemory":
                    break;
                case "AvailablePhysicalMemory":
                    return "";
                default:
                    return $"Missing Case for {key}";
            }
            return null;
        }

我试图获取以下“获取主板ID”

public static string GetMotherBoardId()
        {
            string mbInfo = string.Empty;
            ManagementScope scope = new ManagementScope("\\\\" + Environment.MachineName + "\\root\\cimv2");
            scope.Connect();
            ManagementObject wmiClass = new ManagementObject(scope,
                new ManagementPath("Win32_BaseBoard.Tag=\"Base Board\""), new ObjectGetOptions());

            foreach (PropertyData propData in wmiClass.Properties)
            {
                if (propData.Name == "SerialNumber")
                    mbInfo = $"{propData.Name,-25}{Convert.ToString(propData.Value)}";
            }

            return mbInfo;
        }

这会引发错误，因为系统。当前仅Windows桌面应用程序支持管理。

如何从运行我的UWP应用的本地PC获取上述所有属性。

还尝试了如下所示的powershell脚本

using (PowerShell powerShellInstance = PowerShell.Create())
                    {
                        powerShellInstance.AddCommand("get-wmiobject");
                        powerShellInstance.AddParameter("class", "Win32_ComputerSystemProduct");
                        //powerShellInstance.AddScript(
                        //    "get-wmiobject Win32_ComputerSystemProduct | Select-Object -ExpandProperty UUID");
                        Collection<PSObject> psOutput = powerShellInstance.Invoke();

                    }

出现以下错误

“ get-wmiobject”一词无法识别为cmdlet的名称，功能，脚本文件或可操作程序。检查拼写名称，或者如果包含路径，请确认路径正确，并再试一次。

更新

遵循本文https://docs.microsoft.com/en-us/windows/desktop/wmisdk/retrieving-an-instance，但仍然失败

string Namespace = @"root\cimv2";
string className = "Win32_LogicalDisk";

CimInstance myDrive = new CimInstance(className, Namespace);
CimSession mySession = CimSession.Create("localhost");
CimInstance searchInstance = mySession.GetInstance(Namespace, myDrive);

引发以下错误

客户端无法访问CIM资源。

当我尝试

  ManagementObjectSearcher mgmtObjSearcher = new ManagementObjectSearcher("SELECT * FROM Win32_LogicalDisk");
                    ManagementObjectCollection colDisks = mgmtObjSearcher.Get();

我收到此错误

目前仅Windows桌面支持System.Management 应用程序。

当我尝试这个

string command = "Get-Command Write-Output";
                    using (var ps = PowerShell.Create())
                    {
                        var results = ps.AddScript(command).Invoke();
                        foreach (var result in results)
                        {
                           Console.WriteLine(result.ToString());
                        }
                        ps.Commands.Clear();
                    }

我收到此错误

创建管道时发生错误。 ->找不到方法： 'System.Text.StringBuilder System.Text.StringBuilder.Append（System.Text.StringBuilder）'。

我非常感谢您的帮助。

我根据Microsoft工具包SystemInformation帮助程序中的数据，NetworkInformation类的主机名，TimeZone.CurrentTimeZone的时区和HomeGeographicRegion的SystemLocale填充了您的开关

我没有填写TotalPhysicalMemory，因为在UWP中您无法获取系统RAM信息，因为它是沙箱。但是您可以从MemoryManager

获取应用程序的内存使用限制

对于SerialNumber，您可以使用SystemIdentification.GetSystemIdForPublisher()接收原始数据作为缓冲区，您可以对其进行处理。

private static string SystemInfo(string key)
{
   EasClientDeviceInformation deviceInfo = new EasClientDeviceInformation();
   switch (key)
   {
     case "SerialNumber":
        break ;
     case "UuId":
        return deviceInfo.Id.ToString();
     case "HostName":
        var hostNames = NetworkInformation.GetHostNames();
        return  hostNames.FirstOrDefault(name => name.Type == HostNameType.DomainName)?.DisplayName ?? "???";                     
     case "OsVersion":
        ulong version = ulong.Parse(AnalyticsInfo.VersionInfo.DeviceFamilyVersion);
        return  ((version & 0xFFFF000000000000L) >> 48).ToString()+"."+
          ((version & 0x0000FFFF00000000L) >> 32).ToString()+"."+((version & 0x00000000FFFF0000L) >> 16).ToString()+"."+(version & 0x000000000000FFFFL).ToString();
     case "OsManufacturer":
        return deviceInfo.OperatingSystem;
     case "DeviceId":
        return "";
     case "SystemManufacturer":
        return deviceInfo.SystemManufacturer; 
     case "SystemModel":
        return deviceInfo.SystemProductName;
     case "SystemType":
        return Package.Current.Id.Architecture.ToString();
     case "SystemLocale":
        return Windows.System.UserProfile.GlobalizationPreferences.HomeGeographicRegion;
     case "TimeZone":
        return TimeZone.CurrentTimeZone.StandardName.ToString();
     case "TotalPhysicalMemory":
        break;
     case "AvailablePhysicalMemory":
        return ((float)MemoryManager.AppMemoryUsageLimit / 1024 / 1024).ToString();
     default:
        return $"Missing Case for {key}";
    }
  return null;
}
