在Windows中，我們對我們的Monitros信息 - 一些獨特的名稱和編號。例如顯示器ID和序列號
我qeuestion如何讓C＃中的信息，因爲我知道該序列號，我們可以從WMI得到： 根\ WMI - > WmiMonitorID
約顯示： 根/ CIMV2 Win32_DesktopMonitor
但我必須有這個infromation在一起，它meens Aceer S/N XXX具有ID 1在Windows
有一些人的想法？
作爲一個例子，我們用它來使用WMI從主HDD取回序列：
var search = new ManagementObjectSearcher("select * from Win32_LogicalDisk where DeviceID = 'C:'");
var serials = search.Get().OfType<ManagementObject>();
m_clientToken = serials.ElementAt(0)["VolumeSerialNumber"].ToString();
也許你可以利用它來獲取顯示器的信息，因爲你知道哪管理對象進行搜索。你基本上使用SQL來檢索你要找的東西。
在我看來，這根/ CIMV2/Win32_DesktopMonitor/PnPDeviceID（1）和根/ WMI/WMIMonitorId/實例名（2）幾乎相同
我發現我的計算機上的以下使用WMI Explorer
（1）DISPLAY \ HWP2868 \ 5 & 3EB7FBC UID16777472
（2）DISPLAY \ HWP2868 \ 5 & 3eb7fbc UID16777472_0
有兩點不同：在（2）和所述事實結束時_0那部分（2）是下殼。
我沒有比此刻參考一臺顯示器較多，因此我不能爲您提供更準確的方式向兩個條目關聯。但它看起來像你對我可以寫兩個查詢，修改其中的一個搜索條件匹配其他的格式。但是你需要調查是否有可靠的模式來做到這一點。
無論如何，似乎是足夠的通用元素，如果不通過查詢，能夠在代碼中進行匹配。
這給一個鏡頭：
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"]);
編輯：
下面是一個好看的類的鏈接，將檢索顯示器的細節：
這裏是與上述鏈接關聯的類。它應該給你你需要了解和全面掌握

同樣適用於我：Win32_DesktopMonitor顯示2，WMIMonitorId顯示5。 –
感謝您的答覆。我知道如何獲得SERIALNUMBER信息，但問題是如何得到這樣的信息：我們有3個顯示器：S/N：XXX，S/N：YYY，S/N：ZZZ和我wolud喜歡什麼現在是這種顯示器，其中顯示器是首先在Windows的ID，第二... – jeremmy
