[C#]
public static void DrawArrow(

   int angle
);

Parameters

g: The Graphics surface to draw.
brush: The brush used to fill the arrow.
location: The top-left corner of the arrow.
size: The width of the longest edge of the arrow. Standard sizes are 7 for menu items and scrollbars, 3 for toolbar button drop-down arrows, or 5 for combo box drop-down arrows.
angle: The direction the arrow points, in degrees clockwise from the x-axis. For example, 0 points left, and 90 points down. The angle must be divisible by 90.

Remarks

Several methods exist in ControlPaint to draw various styles of triangle arrows, but all of them use a fixed size and color. DrawArrow enables you to provide a custom color for an arrow and to draw it in any direction, at any size.
