显示器ID和序列号 [英] Monitor ID and Serial Number

问题描述

在Windows中，我们具有有关Monitros的信息-一些唯一的名称和ID.例如

In Windows we have information about our Monitros - some unique name and id. e.g.

1. 宏cer xxx
2. 三星xxx

我很想知道如何在C#中获取信息，因为我知道我们可以从WMI获得序列号:root \ WMI-> WmiMonitorID

I have qeuestion how to get the information in C#, because I know that serial number we can get from WMI: root\WMI -> WmiMonitorID

以及有关显示:root/CIMV2 Win32_DesktopMonitor

and about displays: root/CIMV2 Win32_DesktopMonitor

但是我必须同时拥有这个信息，它表示Windows中Aceer S/N xxx的ID为1

But I have to have this infromation together, it meens Aceer S/N xxx have id 1 in Windows

有人有想法吗?

推荐答案

试一下:

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:

这是指向一个漂亮的类的链接，该类将检索监视器详细信息:

And here's a link to a nice looking class that will retrieve the monitor details:

这是与上面的链接关联的类.它应该为您提供有关显示器所需的一切:

Here is the class associated with the above link. It should give you everything you need about the monitor:
