Can WinForm use system dark mode theme like explorer or StartAllBack?

I've tried these things:

int trueValue = 0x01, falseValue = 0x00;
SetWindowTheme(this.Handle, "DarkMode_Explorer", null);
DwmSetWindowAttribute(this.Handle, DwmWindowAttribute.DWMWA_USE_IMMERSIVE_DARK_MODE, ref trueValue, Marshal.SizeOf(typeof(int)));
DwmSetWindowAttribute(this.Handle, DwmWindowAttribute.DWMWA_MICA_EFFECT, ref trueValue, Marshal.SizeOf(typeof(int)));

But these only make the titlebar and scrollbar in dark, no difference for other controls.

How to make all controls to system dark style, like this:

By defining everything in terms of the system colours? https://learn.microsoft.com/en-us/dotnet/api/system.drawing.systemcolors?view=net-6.0 Or by using some other system to define your own colour themes. – Jeremy Lakeman Jul 15 '22 at 02:55
Something like Button border, TabControl seems cannot be changed colours in SystemColors. – Cmo Sekil Jul 18 '22 at 03:52
Does this also darkens the scrollbar in Windows 11? – eri0o Apr 02 '23 at 18:17
@eri0o Yes, it does. – Cmo Sekil Apr 04 '23 at 05:16
