Parameters

hdc

Handle to a device context where the gradient effect will be displayed.

destRect

Rectangle to be used as the display destination rectangle.

gradientStyle

Gradient style. For possible values refer to SpecialEffectsGradientStyle.

startColor

Value that specifies the starting color.

endColor

Value that specifies the ending color.

steps

Number of gradient color steps. Valid values are 2 to 256.

This Example shows the minimum requirements for using the GradientFillRectangle method to draw and fill a rectangle with a color gradient.
