在 Windows 中，我们有关于 Monnitros 的信息 - 一些唯一的名称和 ID。例如
我对如何在 C# 中获取信息有疑问，因为我知道我们可以从 WMI 获得序列号： root\WMI -> WmiMonitorID
关于显示器： root/CIMV2 Win32_DesktopMonitor
但我必须将这些信息放在一起，这意味着 Aceer S/N xxx 在 Windows 中具有 id 1
有人知道吗？
【问题讨论】：
试一试：
using System.Management;
ManagementObjectSearcher searcher = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM Win32_DesktopMonitor");
foreach (ManagementObject obj in searcher.Get())
Console.WriteLine("Description: {0}", obj ["Description"]);
编辑：
这是一个漂亮的类的链接，它将检索监视器的详细信息：
这是与上述链接关联的类。它应该为您提供有关显示器所需的一切：

root/CIMV2/Win32_DesktopMonitor/PnPDeviceID 仅显示我的 5 台显示器中的 2 台 和 root/WMI/WMIMonitorId/InstanceName 显示我的所有 5 台显示器
strComputer = "."
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\WMI")
Set colItems = objWMIService.ExecQuery( _
"SELECT * FROM WmiMonitorID",,48)
For Each objItem in colItems
Wscript.Echo "-----------------------------------"
Wscript.Echo "WmiMonitorID instance"
Wscript.Echo "-----------------------------------"
Wscript.Echo "InstanceName: " & objItem.InstanceName

作为示例，我们使用它来使用 WMI 从主 HDD 检索序列：
var search = new ManagementObjectSearcher("select * from Win32_LogicalDisk where DeviceID = 'C:'");
var serials = search.Get().OfType<ManagementObject>();
m_clientToken = serials.ElementAt(0)["VolumeSerialNumber"].ToString();
也许您可以利用它来获取您的监视器信息，因为您知道要搜索哪个管理对象。您基本上使用 SQL 来检索您要查找的内容。
【讨论】：
在我看来 root/CIMV2/Win32_DesktopMonitor/PnPDeviceID (1) 和 root/WMI/WMIMonitorId/InstanceName (2) 差不多 em> 相同
我使用WMI Explorer在我的电脑上找到了以下内容
(1) 显示\HWP2868\5&3EB7FBC&0&UID16777472
(2) 显示\HWP2868\5&3eb7fbc&0&UID16777472_0
有两个区别：(2) 末尾的 _0 和 (2) 的部分是小写的事实。
目前我没有多个显示器可供参考，因此我无法为您提供更准确的方法来关联这两个条目。但在我看来，您可以编写两个查询，修改其中一个的搜索条件以匹配另一个的格式。但是您需要调查是否有可靠的模式来执行此操作。
无论如何，如果不是通过查询，似乎有足够的通用元素能够在代码中进行匹配。
