如何在 C# 中更改 Windows 窗体中的系统突出显示颜色？

Question

Is there a way to change the "default windows system blue" highlight color in all the controls in a windows form?

Including textbox, datetimepicker and all of them.

Thank you.

Edit The highlight color is when a user select the text inside the control, normaly it's blue. Can't change the system highlight color and don't want to. I'm interested especially on 3 controls: TextBox, DateTimePicker and NumericUpDown.

By all controls I'll assume you mean all of them that would normally have a highlight color... You simply use the SelectionColor property of highlight-able controls.

For example, it can be used like this:

RichTextBox.SelectionColor = Color.Aqua;

This would set the highlight color of the RichTextBox to Aqua. If you however wanted all controls to be highlighted... You would have to override their drawing and force them to redraw while the mouse is clicked and dragged over the area which they reside.
