[英]How do I get the actual Monitor name? as seen in the resolution dialog
我正在嘗試為我的系統上的監視器獲取友好名稱。 我正在使用C＃。
我試過Screen ， //./DisplayXX給了我//./DisplayXX 。 我也嘗試過Win32_DesktopMonitor和EnumDisplayDevices ，它們都給我//./DisplayXX或Generic Monitor的//./DisplayXX ，而我知道我的顯示名稱是SyncMaster和SM2333T 。
現在，Windows知道這些監視器是什么，使用正確的名稱在“ 設備和打印機”窗口中顯示它們，並在用於設置位置和分辨率的對話框中顯示它們。
我在哪里可以從中獲取這些名稱？ 我已經查看了注冊表，似乎無法找到它們，所以任何幫助都會很棒。
解決方案：我遇到的問題是第二次調用EnumDisplayDevices時再次將iDevNum設置為id，這意味着我試圖從錯誤的位置獲取數據，然后將其替換為0，它完美地工作，請參閱下面的碼。
var device = new DISPLAY_DEVICE();
device.cb = Marshal.SizeOf(device);
try
{
for (uint id = 0; EnumDisplayDevices(null, id, ref device, 0); id++)
{
Console.WriteLine(String.Format("{0}, {1}, {2}, {3}, {4}, {5}", id, device.DeviceName, device.DeviceString, device.StateFlags, device.DeviceID, device.DeviceKey));
Console.WriteLine();
device.cb = Marshal.SizeOf(device);
EnumDisplayDevices(device.DeviceName, 0, ref device, 0);
Console.WriteLine(String.Format("{0}, {1}, {2}, {3}, {4}, {5}", id, device.DeviceName, device.DeviceString, device.StateFlags, device.DeviceID, device.DeviceKey));
device.cb = Marshal.SizeOf(device);
device.cb = Marshal.SizeOf(device);
return;
}
}
}
catch (Exception ex)
{
Console.WriteLine(String.Format("{0}", ex.ToString()));
}
仔細檢查！ 這就是你要找的，你現在可以編寫Screen.PrimaryScreen.DeviceFriendlyName()並獲取監視器設備的真實名稱。
（是的，它與解決方案對話框中的名稱相同）
雖然我確實添加了一些個人觸摸來包裝這些代碼但我沒有創建它的Hard-Core部分，所以我要感謝2位開發人員，MS開發人員提供了C ++的基本知識，以及匿名開發人員翻譯了這些必需品到C＃代碼。

在從EnumDisplayDevices獲得類似//./DisplayX的DisplayDevice.DeviceName之后，你應該第二次調用'EnumDisplayDevices'，這次提供你從前一個調用獲得的'DisplayDevice.DeviceName'作為lpDevice ，'0 '作為iDevNum 。 然后，您將在DisplayDevice.DeviceString擁有監視器名稱。
幾乎可以通過SetupAPI函數系列獲得此信息。 我不記得我頭腦中的具體細節，但您需要獲取所有監視器設備（GUID_DEVINTERFACE_MONITOR）並獲取其友好名稱（SPDRP_FRIENDLYNAME）。
從這里： 獲取精確的監視器/顯示/屏幕名稱
好吧，這個問題很老，但是，為了谷歌重定向，我建議我的'WindowsDisplayAPI'庫。
https://www.nuget.org/packages/WindowsDisplayAPI
使用該庫，有多種方法可以獲取顯示名稱。 最簡單的方法是：
foreach (var display in Display.GetDisplays())
{
Console.WriteLine(display.DeviceName);
}
但這是使用舊的API，如果您確定您的程序至少針對Windows Vista，我建議使用以下代碼：
foreach (var target in DisplayConfig.PathDisplayTarget.GetDisplayTargets())
{
Console.WriteLine(target.FriendlyName);
}
