监视器ID和序列号
本文关键字：序列号 ID 监视器 | 更新日期: 2023-09-27 18:07:29
在Windows中，我们有关于监视器的信息-一些唯一的名称和id。例如
- 宏碁xxx 三星xxx
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
和about显示:根/CIMV2 Win32_DesktopMonitor
但是我必须把这些信息放在一起，这意味着在Windows
中，Aceer S/N xxx的id为1有人知道吗?
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:
这里是一个链接到一个漂亮的类，将检索监视器的详细信息:
http://wmimonitor.svn.sourceforge.net/viewvc/wmimonitor/DisplayInfoWMIProvider/WMIProvider/WMIProvider.cs?view=markup下面是与上面链接关联的类。它应该能提供您所需要的有关显示器的一切信息:

root/CIMV2/Win32_DesktopMonitor/PnPDeviceID . net只显示我5个显示器中的2个都和根/WMI/WMIMonitorId/显示所有5个监视器
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
Next
作为一个例子，我们使用WMI从主硬盘检索串行:
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Mgmt Object。基本上是用SQL来检索你要找的
在我看来，根/CIMV2/Win32_DesktopMonitor/PnPDeviceID(1)和根/WMI/WMIMonitorId/InstanceName (2) 几乎相同
我使用WMI资源管理器在我的计算机上发现了以下内容
(1)显示' HWP2868 ' 5和3 eb7fbc& 0, UID16777472
(2)显示' HWP2868 ' 5和3 eb7fbc& 0, UID16777472_0
有两个不同之处:(2)末尾的_0和(2)的部分是小写的。
我目前只有一个以上的监视器可供参考，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，修改其中一个查询的搜索条件以匹配另一个查询的格式。但是您需要调查是否存在这样做的可靠模式。
无论如何，似乎有足够多的公共元素可以在代码中进行匹配，如果不是通过查询。
