特定屏幕的可用分辨率

Question

我可能有 2 个 monitor/screens 连接到我的机器。我想知道特定屏幕的所有可用分辨率（我有一个 System.Windows.Forms.Screen 类型的实例）。

我看过以下内容： How to list available video modes using C#?

List of valid resolutions for a given Screen?

但它们都给出了所有显示器的结果，而不仅仅是特定的显示器。有什么建议么？谢谢！！！

这是关于我的 2 个屏幕的信息：

在第一个链接中，您被告知 EnumDisplaySettings。花几秒钟 lookup that function 并且 第一个参数 是

string that specifies the display device about whose graphics mode the function will obtain information.

这是一个示例 class，用于获取有关显示器的信息。我故意省略了 DEVMODE 因为你已经知道了。

public class NativeMethods
{
    [DllImport("user32.dll")]
    public static extern bool EnumDisplaySettings(string deviceName, int modeNum, ref DEVMODE devMode);
    [DllImport("user32.dll")]
    public static extern bool EnumDisplayDevices(string deviceName, int modeNum, ref DISPLAY_DEVICE displayDevice, int flags);
}


[StructLayout(LayoutKind.Sequential)]
public struct DISPLAY_DEVICE
{
    public int cb;
    [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 32)]
    public string DeviceName;
    [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 128)]
    public string DeviceString;
    public int StateFlags;
    [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 128)]
    public string DeviceID;
    [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 128)]
    public string DeviceKey;
}

static class Display
{
    public static List<DISPLAY_DEVICE> GetGraphicsAdapters()
    {
        int i = 0;
        DISPLAY_DEVICE displayDevice = new DISPLAY_DEVICE();
        List<DISPLAY_DEVICE> result = new List<DISPLAY_DEVICE>();
        displayDevice.cb = Marshal.SizeOf(displayDevice);
        while (NativeMethods.EnumDisplayDevices(null, i, ref displayDevice, 1))
        {
            result.Add(displayDevice);
            i++;
        }

        return result;
    }

    public static List<DISPLAY_DEVICE> GetMonitors(string graphicsAdapter)
    {

        DISPLAY_DEVICE displayDevice = new DISPLAY_DEVICE();
        List<DISPLAY_DEVICE> result = new List<DISPLAY_DEVICE>();
        int i = 0;
        displayDevice.cb = Marshal.SizeOf(displayDevice);
        while (NativeMethods.EnumDisplayDevices(graphicsAdapter, i, ref displayDevice, 0))
        {
            result.Add(displayDevice);
            i++;
        }

        return result;
    }

    public static List<DEVMODE> GetDeviceModes(string graphicsAdapter)
    {
        int i = 0;
        DEVMODE devMode = new DEVMODE();
        List<DEVMODE> result = new List<DEVMODE>();
        while (NativeMethods.EnumDisplaySettings(graphicsAdapter, i, ref devMode))
        {
            result.Add(devMode);
            i++;
        }
        return result;
    }
}
