我的应用程序可以使用双显示器配置。在应用程序的设置中,我列出了用户将选择其辅助屏幕的可用显示。
我使用以下方式获取(真实)监视器设备名称:
http://msdn.microsoft.com/en-us/library/aa394122%28VS.85%29.aspx
SelectQuery q = new SelectQuery("SELECT Name, DeviceID, ScreenHeight, ScreenWidth FROM Win32_DesktopMonitor");
using (ManagementObjectSearcher mos = new ManagementObjectSearcher(q))
{
foreach (ManagementObject mo in mos.Get())
{
...
}
}
但是我还需要显示范围(顶部,左边等),这不会给我。但是System.Windows.Forms.Screen
确实给了我界限但不是真正的设备名称。如果我确定每次都以相同的顺序返回设备,我可以一起使用它们。这些都会每次按时间顺序返回“设备1”,“设备2”等吗?或者有没有一种方法可以包含我所需要的所有信息?
[编辑] 嗯。 Win32_DesptopMonitor不给我我的辅助监视器名称。它只是称它为Default Monitor。它在我的主要版本之前列出它。
[EDIT2] 好吧,这些名字和他们的决议搞砸了.....任何人都知道这里发生了什么?
答案 0 :(得分:1)
我在使用Win API调用之前已经这样做了。我粘贴了下面的代码,这可能对你有所帮助......
public void Store()
{
Screens.Clear();
uint iAdaptorNum = 0;
Win.User32.DISPLAY_DEVICE adaptor = new Win.User32.DISPLAY_DEVICE();
adaptor.cb = (short)Marshal.SizeOf(adaptor);
Win.User32.DISPLAY_DEVICE dd = new Win.User32.DISPLAY_DEVICE();
dd.cb = (short)Marshal.SizeOf(dd);
while (Win.User32.EnumDisplayDevices(null, iAdaptorNum, ref adaptor, Win.User32.EDD_GET_DEVICE_INTERFACE_NAME))
{
uint iDevNum = 0;
while (Win.User32.EnumDisplayDevices(adaptor.DeviceName, iDevNum, ref dd, Win.User32.EDD_GET_DEVICE_INTERFACE_NAME))
{
log.WriteFormat(LogLevel.Debug, "Adaptor {0}:{1} {2}='{3}', Device {4}='{5}', State flags = {4}",
iAdaptorNum, iDevNum, adaptor.DeviceName, adaptor.DeviceString, dd.DeviceName, dd.DeviceString, dd.StateFlags);
if ((dd.StateFlags & Win.User32.DisplayDeviceStateFlags.AttachedToDesktop) > 0)
Screens.Add(new ScreenInfo(adaptor, dd));
iDevNum++;
}
iAdaptorNum++;
}
}
这就是在new ScreenInfo
后面调用的内容:
public void StoreScreen(Win.User32.DISPLAY_DEVICE Adaptor, Win.User32.DISPLAY_DEVICE Device)
{
adaptor = Adaptor.DeviceName;
device = Device.DeviceName;
name = string.Format("{0} on {1}", Device.DeviceString, Adaptor.DeviceString);
Win.User32.DEVMODE dm = newDevMode();
if (Win.User32.EnumDisplaySettings(Adaptor.DeviceName, Win.User32.ENUM_CURRENT_SETTINGS, ref dm) != 0)
{
isAttached = (Adaptor.StateFlags & Win.User32.DisplayDeviceStateFlags.AttachedToDesktop) > 0;
isPrimary = (Adaptor.StateFlags & Win.User32.DisplayDeviceStateFlags.PrimaryDevice) > 0;
mode = findMode(Adaptor.DeviceName, dm);
if ((dm.dmFields & Win.User32.DM.PelsWidth) > 0) width = dm.dmPelsWidth;
if ((dm.dmFields & Win.User32.DM.PelsHeight) > 0) height = dm.dmPelsHeight;
if ((dm.dmFields & Win.User32.DM.BitsPerPixel) > 0) bpp = dm.dmBitsPerPel;
if ((dm.dmFields & Win.User32.DM.Orientation) > 0) orientation = dm.dmOrientation;
if ((dm.dmFields & Win.User32.DM.DisplayFrequency) > 0) frequency = dm.dmDisplayFrequency;
if ((dm.dmFields & Win.User32.DM.DisplayFlags) > 0) flags = dm.dmDisplayFlags;
if ((dm.dmFields & Win.User32.DM.Position) > 0)
{
posX = dm.dmPosition.x;
posY = dm.dmPosition.y;
}
}
}
private static Win.User32.DEVMODE newDevMode()
{
Win.User32.DEVMODE dm = new Win.User32.DEVMODE();
dm.dmDeviceName = new String(new char[31]);
dm.dmFormName = new String(new char[31]);
dm.dmSize = (short)Marshal.SizeOf(dm);
return dm;
}
