如何在XNA中获得支持的屏幕分辨率?就像在Windows中更改屏幕分辨率一样,而不是为您提供所有可能选择的列表时,它只为您提供了一些选项。

请使用:
foreach (DisplayMode mode in GraphicsAdapter.DefaultAdapter.SupportedDisplayModes) {
//mode.whatever (and use any of avaliable information)
}
但是它会给你很少的重复,因为它也会影响refrash率,所以你可能会包括aswel,或者做一些过滤。

我不是最新的XNA,但我并不认为有一个快速简单的功能。有一种方法可以使用旧的WinForms API,但由于我个人不想在其他应用程序中链接,最简单的方法是使用本机函数。
首先,定义将使用的本机结构:
[StructLayout(LayoutKind.Sequential)]
internal struct DEVMODE
{
private const int CCHDEVICENAME = 0x20;
private const int CCHFORMNAME = 0x20;
[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 0x20)]
public string dmDeviceName;
public short dmSpecVersion;
public short dmDriverVersion;
public short dmSize;
public short dmDriverExtra;
public int dmFields;
public int dmPositionX;
public int dmPositionY;
public int dmDisplayOrientation;
public int dmDisplayFixedOutput;
public short dmColor;
public short dmDuplex;
public short dmYResolution;
public short dmTTOption;
public short dmCollate;
[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 0x20)]
public string dmFormName;
public short dmLogPixels;
public int dmBitsPerPel;
public int dmPelsWidth;
public int dmPelsHeight;
public int dmDisplayFlags;
public int dmDisplayFrequency;
public int dmICMMethod;
public int dmICMIntent;
public int dmMediaType;
public int dmDitherType;
public int dmReserved1;
public int dmReserved2;
public int dmPanningWidth;
public int dmPanningHeight;
}
我们还需要定义我们将使用的两个本机函数:
[DllImport("user32.dll")]
private static extern bool EnumDisplaySettings(string lpszDeviceName, int iModeNum, ref DEVMODE lpDevMode);
[DllImport("user32.dll")]
private static extern int GetSystemMetrics(int nIndex);
最后,我们的功能列出所有屏幕分辨率,一个用于获取当前屏幕分辨率:
public static List<string> GetScreenResolutions()
{
var resolutions = new List<string>();
try
{
var devMode = new DEVMODE();
int i = 0;
while (EnumDisplaySettings(null, i, ref devMode))
{
resolutions.Add(string.Format("{0}x{1}", devMode.dmPelsWidth, devMode.dmPelsHeight));
i++;
}
resolutions = resolutions.Distinct(StringComparer.InvariantCulture).ToList();
}
catch (Exception ex)
{
Console.WriteLine("Could not get screen resolutions.");
}
return resolutions;
}
public static string GetCurrentScreenResolution()
{
int width = GetSystemMetrics(0x00);
int height = GetSystemMetrics(0x01);
return string.Format("{0}x{1}", width, height);
}
