c# - 显示器 ID 和序列号

在 Windows 中,我们有关于我们的 Monitros 的信息——一些唯一的名称和 ID。例如

  1. 宏碁 xxx
  2. 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 获取序列号:root\WMI -> WmiMonitorID

关于显示:根/CIMV2 Win32_DesktopMonitor

但我必须把这些信息放在一起,这意味着 Aceer S/N xxx 在 Windows 中的 ID 为 1

有人知道吗?

最佳答案

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"]);

这里是一个漂亮的类的链接,可以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:
